1. Introduction

Welcome to PGI Visual Fortran®, a set of Fortran compilers and development tools for Windows integrated with Microsoft Visual Studio.

PGI Visual Fortran (PVF®) is licensed using FLEXnet, the flexible license management system from Flexera Software*. Instructions for obtaining a permanent license are included in your order confirmation. More information is available in Licensing.

1.1. Product Overview

PVF is integrated with two versions of Microsoft Visual Studio. Currently, Visual Studio 2013 and 2015 are supported. Throughout this document, "PGI Visual Fortran" refers to PVF integrated with any of the supported versions of Visual Studio. Similarly, "Microsoft Visual Studio" refers to Visual Studio 2013 and VS 2015. When it is necessary to distinguish among the products, the document does so.

Single-user node-locked and multi-user network floating license options are available for both products. When a node-locked license is used, one user at a time can use PVF on the single system where it is installed. When a network floating license is used, a system is selected as the server and it controls the licensing, and users from any of the client machines connected to the license server can use PVF. Thus multiple users can simultaneously use PVF, up to the maximum number of users allowed by the license.

PVF provides a complete Fortran development environment fully integrated with Microsoft Visual Studio. It includes a custom Fortran Build Engine that automatically derives build dependencies, Fortran extensions to the Visual Studio editor, a custom PGI Debug Engine integrated with the Visual Studio debugger, PGI Fortran compilers, and PVF-specific property pages to control the configuration of all of these.

Release 2017 of PGI Visual Fortran includes the following components:

  • PGFORTRAN OpenMP and auto-parallelizing Fortran 90/95/2003 compiler.
  • PGF77 OpenMP and auto-parallelizing FORTRAN 77 compiler.
  • PVF Visual Studio integration components.

If you do not already have Microsoft Visual Studio on your system, be sure to get the PVF installation package that contains the Visual Studio 2015 Shell.

1.2. Microsoft Build Tools

PVF on all Windows systems includes the Microsoft Open Tools. These files are required in addition to the files Microsoft provides in the Windows SDK.

1.3. Terms and Definitions

2. Installation Overview

There are a number of steps required to successfully install PGI Visual Fortran. This document provides the details related to these steps.

2.1. Before You Begin

Before you begin the installation, it is essential that you understand the flow of the installation process, illustrated in the following diagram.

Figure 1. PVF Installation Overview
PVF Installation Overview.

For more complete information on these steps and the specific actions to take for your operating system, refer to the remainder of this document.

3. Licensing

PGI Visual Fortran is a license-managed product. PGI software licensing uses the FlexNet Publisher (FNP) license management system from Flexera Software.

PGI software licensing uses the FlexNet Publisher (FNP) license management system from Flexera Software.

3.1. Licensing Terminology

Before discussing licensing, it is useful to have common terminology.

License
A legal agreement between NVIDIA and PGI end-users, to which users assent upon installation of any PGI product. The terms of the License are kept up-to-date in documents on pgicompilers.com and in the $PGI/<platform>/<rel_number> directory of every PGI software installation.
License keys
ASCII text strings that enable use of the PGI software and are intended to enforce the terms of the License. License keys are typically stored in a file called license.dat that is accessible to the systems for which the PGI software is licensed.
PIN
Product Identification Number, a unique 6-digit number associated with a purchased license. This PIN is included in your PGI order confirmation. The PIN can also be found in your PGI license file after VENDOR_STRING=.

3.2. Licensing Keys

PGI Visual Fortran includes the PGI License Setup tool to help automate your license retrieval and installation process. You use this tool to obtain either a trial or a permanent license key.

3.2.1. Licensing Key Options

There are four types of license key options: starter, developer, community, and permanent.

Starter License Keys
Time-limited evaluation license keys provided on request by PGI. Starter license keys do not use FlexNet daemons.
Permanent License Keys
Purchased PGI licenses come with permanent license keys. Permanent license keys are perpetual, meaning they remain valid indefinitely with eligible versions of PGI software. Permanent license keys require FlexNet license daemons either locally or on a separate license server system.

For specific details on how to obtain a license key, refer to Step 2 of Basic PVF Installation.

3.2.2. Licensing Key Capabilities

At the conclusion of the starter license key evaluation interval, the PGI compilers and tools, along with any executable files generated with them will cease to function. To retain functionality, any executables, object files, or libraries created using the PGI compilers with starter license keys must be recompiled with either a developer, community or permanent license key.

Executable files generated using developer license keys are restricted to running only on the same system as they were compiled. Developer license keys may not be moved between machines.

Executable files generated using community or permanent license keys are unconstrained, and run on any compatible system regardless of whether the PGI compilers are installed.

3.2.3. Licensing Key Comparisons

Table 3. License Key Comparisons
License Key Type Starter Developer Community Permanent
Limited duration Yes - 30 days Yes - 1 year Yes - 1 year No
Limited functionality Yes Yes No No

3.2.4. Licensing Key Dependencies

When using permanent license keys, you must install the PGI software before obtaining your license keys. The license key generation process requires information generated during software installation. Starter and community license keys do not have this dependency.

Important: If you change the configuration of your system by adding or removing hardware, permanent license keys may become invalid. You will need to obtain new license keys from www.pgicompilers.com or using the license setup tool described below.

3.3. The FlexNet License Manager

PGI Visual Fortran is licensed using the FlexNet software license management system from Flexera Software.

As part of the installation process, you install and configure the FlexNet license management software. There are two permanent licensing options using FlexNet-style licensing.

  • Node-locked allows any user on a single system to run the software, with access restricted to that prespecified machine.
  • Network floating license supports a more flexible licensing system.
    • There is one license server on a network and any system on that network with a properly configured version of PGI Visual Fortran installed can run the software.
    • Multiple users can use PGI Visual Fortran simultaneously from multiple systems on the network.
    • The limitation on the number of users is determined by the number of seats that were purchased with the license.
Note: A user continues to keep a license checked out as long as they have a PVF project open or the PVF debugger is attached to a process.

3.4. PGI Licensing Considerations

PGI licensing is the common method used by all PGI products to control access. The License Service is made up of two components:

  • The lmgrd daemon is the common license manager component used by all FlexNet licenses. It oversees the distribution of license seats.
  • The pgroupd daemon is unique to PGI and reads and decodes the PGI license file.

A license is created using the hostname and the hostid of the license server. These rules apply:

  • Only one copy of lmgrd runs on the license server, and is used by all FlexNet-type licenses. For both floating or node-locked licenses, only a single license server is required.
  • Only one PGI license per license server. You may have FlexNet licenses for other non-PGI software packages, but you may only have one PGI license per server. More than one causes the license server to malfunction.
  • The hostname used in the license file should be understood by all of the systems using the compilers. Entering the command ping hostname should result in the same IP address on all of the systems, including the license server itself.
  • The hostid is usually the MAC (inet address) of a device (/sbin/ifconfig on Linux and macOS, ipconfig /all on Windows), which can be detected by the FlexNet utilities. It is usually best to choose the MAC associated with the IP address of the server.
  • There is a sequence in which the PGI compilers look for environment variables.
    • The PGI compilers look first at the environment variable $PGROUPD_LICENSE_FILE for the location of the PGI license. This variable is set in the registry on Windows machines, and is specific to PGI products.
    • The PGI compilers next look at the environment variable $LM_LICENSE_FILE for the location of the PGI license. This is a generic variable used by every FlexNet licensed product.
    • The PGI compilers then look at the default location for $PGI/license.dat.
  • On the license server itself, $PGROUPD_LICENSE_FILE and/or $LM_LICENSE_FILE must be the full license pathname, as in /opt/pgi/license.dat on Linux and macOS, or C:\Program Files\PGI\license.dat on Windows.
  • On machines other than the license server, $PGROUPD_LICENSE_FILE and/or $LM_LICENSE_FILE can either be a full pathname to the license file, or port@host such as 27000@hostname.
  • When changing a license file, take care to ensure the license software can read the new license. On Windows and macOS, this means having Admin privileges or sudo capability to copy the license file to its destination. If the license service is already running, you may need to STOP and START it again to make sure the new file is read and not the old file that is stored in cache.
  • When the FlexNet license service detects a problem or an event, it records it in either the flexlm.log file (Linux) or the License.log file (Windows, macOS). If you're having licensing problems, check this file for information.

3.5. License Support

All new PGI licenses include free PGI Support Service during the money-back guarantee period. For more information about this service and how to extend it, refer to Product Support.

4. Installing PGI Visual Fortran

The following process of installing PGI Visual Fortran on a Windows system is applicable to permanent or trial installations. This installation process involves:

  • Installing PVF on a single system.
  • Setting up the license service for permanent licenses.
Note: The following instructions guide you in installing PGI Visual Fortran on a single Windows system. If you are setting up PGI Visual Fortran for use with a network floating license, first refer to PVF Installation on Client.

4.1. Prerequisites

The Microsoft Windows Software Development Kit (SDK) is a prerequisite for all PGI Windows installations.

PGI's compilers leverage the latest Microsoft tool chain. To use these tools on operating systems older than Windows 10, you must first install Microsoft's Update for Universal C Runtime. Download and install this update here: http://support.microsoft.com/en-us/kb/2999226. Depending on the configuration details of your system, this update may have already been installed as part of the automatic Windows Updates applied to your system.

The PVF installer detects the versions of Visual Studio on your system and installs the PVF integration components for those versions.

  • To install PVF for Visual Studio 2015, there are no other prerequisites. However, if you do not already have Visual Studio 2015 installed on your system, be certain to invoke the installation package that includes the Visual Studio 2015 Shell.
  • To install PVF for Visual Studio 2013, you must have Visual Studio 2013 already installed on your system. The PVF 15.10 release for VS 2013 was the last release that included the VS 2013 Shell.

4.2. Basic PVF Installation

Once you have completed the prerequisites, you are ready to install. Follow these steps:

  1. Run the PVF installation package as Administrator. Administrative privileges are required to install PVF.
    • Run the PVF installation executable on the target machine.
    • Follow the directions printed to your screen.
    How to Choose the Correct PVF Download The name of the PVF executable depends on several factors. The following list shows the different package names.
    To install this ... Choose this executable ...
    PVF pvf64-1710.exe
    PVF With VS Shell pvf64-shell-1710.exe
  2. Run PGI Licensing.

    At the conclusion of the installation process, the PVF installer runs the PGI License Setup tool. This tool automates Manual PVF Licensing.

    To use the tool, your computer must meet these prerequisites:

    • Be connected to the Internet.
    • Have Microsoft .NET Framework 2.0 or higher installed.
    • Have Internet Explorer Version 6.0 or higher installed and configured. For PVF 17.10 with Visual Studio 2013, IE version 10.0 or newer is required.

    If your computer is not connected to the Internet or does not meet these minimum prerequisites, then click the tool's Cancel button and run the PGI License Setup tool later. You can locate this tool in the PGI Visual Fortran folder.
    PGI Visual Fortran | Licensing | Generate License

    When you run the program, the PGI License Setup tool walks you through the license installation process. It prompts you for your PGI web account login, which is your email address, your password, and the type of license you wish to install, such as a two-week trial license or a permanent license. The tool also informs you of any problems it experiences with installation and instructs you how to proceed.

  3. Optionally, install a Visual Studio Service Pack.

    Updates to Visual Studio 2015 or 2013 are supported by PVF but you are not required to upgrade.

    You can obtain Visual Studio updates from the Microsoft web page.

  4. Start PGI Visual Fortran.

    Your installation is now complete and you should be able to start up PVF.

    • On Windows 8, 8.1, or Server 2012, click on the Visual Studio icon on the Start screen.
    • For systems with a Start menu, select Start | All Programs | PGI Visual Fortran. Click on the entry for the version of PVF that you want to start.

4.3. Manual PVF Licensing

If you did not successfully run the PGI License Setup tool as described in step 2 of Basic PVF Installation, you can manually install PVF licensing.

The instructions in this section help you obtain a license, put it on your system, and start the PGI License Service so you can use PVF. Manual PVF Licensing requires four basic tasks:

  1. Get a PVF License.
  2. File your license key.
  3. Start the PGI License Service.
  4. Start PGI Visual Fortran.

The following sections describe how to perform these tasks.

  1. Get a PVF license. The PGI Visual Fortran compilers and tools on Windows are license-managed using FLEXnet licensing. This system requires that you possess a valid license for the licensed product. You get the license from the PGI website, https://www.pgicompilers.com/license. If you do not have a web account, go to https://www.pgicompilers.com/register to create one. To obtain a license, you first need to gather the following information:
    • The username and password required to connect to the pgicompilers.com website. This username and password are the same username (email address) and password you used to download the installation software from the web site.
    • The FLEXlm hostid and hostname of the computer on which PGI Visual Fortran is installed.

      Note:

      It is easy to get the hostid and hostname of your system once you have installed the products.

      Open a PVF Command Prompt window. If you have a Start menu, select All Programs | PGI Visual Fortran Command Shells | PVF Cmd. If you have a Start screen, navigate to All Apps, then select the PVF Cmd icon.

    To get the hostid, enter this command at the prompt: CMD> lmutil lmhostid You see output similar to the following in which 12345678abcd is unique to your system.
    lmutil - Copyright (c) 1989-2011 Flexera Software, Inc.
    All Rights Reserved.
    The FLEXnet host ID of this machine is "12345678abcd"      
    To get the hostname, enter this command at the prompt: CMD> lmutil lmhostid -hostname You see output similar to the following in which 12345678abcd is unique to your system.
    lmutil - Copyright (c) 1989-2011 Flexera Software, Inc.
    All Rights Reserved.
    The FLEXnet host ID of this machine is "HOSTNAME=yourHostName"         
    Though the above command returns output in the form HOSTNAME=yourHostName, when you create a license, use only the actual hostname, that is, yourHostName in the hostname field. For example, if the information displayed is HOSTNAME=abcd1234, then use only abcd1234. Using this information, go to the PGI license generation website, log in using your username and password, and generate your license.

    Generate License Keys

    Once you have logged on at https://www.pgicompilers.com/login using your registered PGI web-user email and password, you will see a screen similar to the following one:

    Generate a Permanent License Key
    1. Click Create permanent keys.
    2. Click the PIN associated with the product for which you wish to generate license keys. If you don't see any PINs listed, you first need to tie one to your account:
      • a. Obtain your PIN code from your original PGI order confirmation email, in the section labeled: "SHARING ADMINISTRATION" or contact license@pgroup.com.
      • b. Click the link: Tie a PIN to this account.
      • c. Enter the 16-digit PIN code and follow the instructions provided.
    3. Click License keys to generate the keys.
    Generate a Trial License Key
    1. Click Create trial keys.
    2. Accept the terms of the agreement.
    3. Enter any one of the FLEXnet hostids detected, exactly as it appears in the message that is displayed during installation or when you issue the command: CMD> lmutil lmhostid
    4. Click the Generate License keys button.
  2. File Your License Key. Once you have a PVF license, you must store it with Administrator privileges in the license file on your system, a file called license.dat. In a typical installation configuration, where C: is the system drive, put the license in this file:
    C:\Program Files\PGI\license.dat
    • If you have not previously received license keys from PGI and the license.dat file exists, replace the contents of the license.dat file created during installation with the license keys you generated using the preceding steps. Otherwise, you must create the file.
    • If the license keys in the file are for a previous release of the same product, overwrite the keys.
    • If you have not previously received a license from PGI, you must create this file.
    Note:

    You must have Administrator privileges to modify or replace the license.dat file.

    If your license.dat file already contains keys that you previously received from PGI, first make a copy of the existing license.dat file in case you encounter a problem with the new license.

  3. Start the PGI License Service. The PVF installation creates a Windows Service called PGI License Service. The actions related to this service depend on the type of license you are using:
    • Trial or starter—If you have obtained a trial or starter license, then no action is required.
    • Permanent—If you have obtained a permanent license, the FLEX license system requires that a license server be running. Thus you must now start the PGI License Server.
    As soon as a valid license.dat file is in place, as described in "Step 2. File Your License Key", you can start the PGI License Server.
    1. Open the Services dialog from the Control Panel: Control Panel | Administrative Tools | Services
    2. Scroll through the list and select "PGI License Server".
    3. Select Start, if the PGI service is stopped. If the PGI service is running, STOP and then START it. This process guarantees that the new PGI license is served and that the older, cached PGI license is no longer active.
    Note: The PGI License Server service starts automatically on system reboot provided that the license.dat file contains valid keys.
  4. Start PGI Visual Fortran. Your license setup is now complete and you should be able to start up PVF.
    • On Windows 8, 8.1, or Server 2012, click the Visual Studio icon on the Start screen.
    • For systems with a Start menu, select Start | All Programs | PGI Visual Fortran. Click the entry for the version of PVF that you want to start. .

5. PVF Multi-User Installation and Licensing

If you are installing PGI Visual Fortran for multiple users, you set up one system as a license server and one or more different systems as clients. As you see in scenario A that follows, the license server can also be a client.

When PVF is invoked on one of the client systems, it contacts the license server to check out a network floating PVF license. The steps you take to set up the license server are different than the steps you take to set up the clients. This section describes the entire process.

Server Designation

When you are installing PGI Visual Fortran with the intention of using a multi-user network floating license, you must designate a machine to be the system that serves PGI Visual Fortran licenses. Let's call this machine the FLEX license server.

There are a number of different ways to set up the FLEX license server, and how you choose to proceed depends on your needs. Before you begin the installation, select the scenario that best matches the configuration that you want for your FLEX license server.

This installation guide covers the following situations:

Scenario A: The FLEX license server is a Windows system. You want to install PGI Visual Fortran on it as well as on the client systems.

Scenario B: The FLEX license server is a Windows system. However, you do not want to install PGI Visual Fortran on it.

Scenario C: The FLEX license server is a Linux system.

Once you have determined the scenario that fits your needs, move on to the section that provides the specific steps for your licensing server scenario.

5.1. Scenario A - License Server (Windows) with PVF Installed

Use these steps if your FLEX license server is a Windows system and you want to install PGI Visual Fortran on it as well as on the client systems.

  1. Install PVF on the license server. To do this, follow the instructions in Basic PVF Installation.
  2. Enable licensing on the license server. To do this, follow the instructions in Manual PVF Licensing.
  3. Install PVF on each client. To do this, follow the instructions in PVF Installation on Client.

5.2. Scenario B - License Server (Windows) without PVF Installed

Use these steps if your FLEX license server is a Windows system but you do not want to install PGI Visual Fortran on it.

  1. Install the PGI License Server on the license server. To use a Windows system as the FLEX license server for PVF, the system must have the PGI License Server components installed on it. These components are included in all PGI products, but they are also available in a standalone installation package. First, use the system's Add or Remove Programs Dialog to check for the presence of PGI FLEXlm License Server components:
    • If the PGI FLEXlm License Server 11.13 is installed, proceed to Step 2.
    • If any PGI product is installed that is version 2013 or newer, the system already has the components that it needs. Proceed to Step 2.
    • If any previous version of PGI FLEXlm License Server is installed, use the Add or Remove Programs dialog to uninstall this product. A PVF license requires a newer version of the FLEX tools. Proceed with this step.
    Next, download the PGI License Server 11.13 installation package. Finally, log on to the system as Administrator and run the PGI License Server 11.13 installer.
  2. Enable licensing on the license server. To do this, follow the instructions in Manual PVF Licensing.
  3. Install PVF on each client. To do this, follow the instructions in PVF Installation on Client.

5.3. Scenario C - License Server (Linux)

Use these steps if you use a Linux system as your FLEX license server.

Note: This scenario is only recommended for users already familiar with using FLEX on Linux.
  1. Install the 11.10 FLEX Tools on the Linux license server.

    To use a Linux system as the FLEXnet license server for PGI Visual Fortran, FLEXnet tools must be installed on the Linux system. Further, these FLEXnet tools must be version 11.10 or newer.

    To download a version of FLEXnet tools for Linux that will support PGI Visual Fortran network floating license keys, go to https://www.pgicompilers.com/support/download_licensing.php.

  2. Obtain a PVF license from PGI. Using the information in your order confirmation, and the hostid and hostname of the Linux FLEX license server system, obtain PVF license keys from https://www.pgicompilers.com.
  3. Add the PVF license to license.dat. Add the PVF license to the license.dat file used by the FLEXnet Tools on the Linux FLEX license server. If necessary, restart the FLEX license server, typically lmgrd.
  4. Install PVF on each client. To do this, follow the instructions for PVF Installation on Client.

5.4. PVF Installation on Client

Use the following steps to install PVF on a client system. You should have already completed the steps listed for setting up the FLEX license server. Your actions, outlined in the previous sections, depend on whether you chose Scenario A, B, or C.

  1. Install PVF on the client. To do this, follow the instructions in Basic PVF Installation.
  2. Fix the license.dat file on the client. This step involves these actions:
    • Put the license.dat file from the FLEX license server on each client. If a license.dat file already exists on the client, then replace it with the one from the server.
    • Change the Startup Type for the PGI License Server on the client from "Automatic" to "Manual".
      This change stops the PGI License Server from automatically starting when the client is rebooted.
    To set the startup type to Manual, do this:
    1. Open the Services dialog from the Control Panel: Control Panel | Administrative Tools | Services
    2. Scroll through the list and select "PGI License Server."
    3. Select "Properties."
    4. In the Properties dialog, from the Startup Type drop-down list, select "Manual."
    5. Click OK.
    Note:

    The default action after a PVF installation is for this service to automatically start after a reboot. The client is obtaining a license from the system on the network that contains the licenses. Setting the client PGI License Server startup type to Manual is an important step.

    Test the licensing setup by starting Visual Studio on the client system and verify that you can create a PVF project.

  3. Repeat both steps 1 and 2 for each client.

6. Use Licensing Environment Variables

This section describes two environment variables that you can use with FLEXnet:
  • PGROUPD_LICENSE_FILE
  • FLEXLM_BATCH

6.1. PGROUPD_LICENSE_FILE

The system environment variable PGROUPD_LICENSE_FILE is not required by PVF, but you can use it to override the default location that is searched for the license.dat file.

To use the system environment variable PGROUPD_LICENSE_FILE, set it to the full path of the license key file. To do this, follow these steps:

  1. Open the System Properties dialog from the Control Panel's System option.
  2. Select the Advanced tab.
  3. Click the Environment Variables button.
    • If PGROUPD_LICENSE_FILE is not already an environment variable, create a new system variable for it. Set its value to the full path of your license.dat file.
    • If PGROUPD_LICENSE_FILE already exists as an environment variable, append the path to the license file in the variable's current value using a semi-colon to separate entries.

6.2. FLEXLM_BATCH

By default, on Windows, the license server creates interactive pop-up messages to issue warnings and errors. This behavior is controlled by the environment variable FLEXLM_BATCH.

Although it is not recommended, you can prevent interactive pop-ups from appearing. To do this, set the environment variable FLEXLM_BATCH to 1.

7. PGI Visual Fortran Default Directory Structure

This section shows the default installation location of the contents of PGI Visual Fortran.This default installation directory depends on your platform.

Note: Throughout this section, we assume that the Windows system drive is C.

On Windows x64 platforms, the default installation directories are

C:\Program Files\PGI
C:\Program Files (x86)\PGI
C:\Program Files (x86)\PGI\Microsoft Visual Studio <N>\PGI Visual Fortran 

where <N> can be either or both 12.0 and 14.0, depending on the versions of Visual Studio installed on your system.

In addition to these product directories, the FLEXnet license management tools are installed here:

C:\Program Files\PGI\flexlm 

8. Common Installation Issues

This section contains information about problems that may occur during the installation process as well as tips on setup information.

8.1. Windows Firewall and PVF Debugging

Microsoft Windows Firewall runs by default on some Windows systems. Unless the PVF debug engine components are included in the Windows Firewall Exceptions list, Windows Firewall may try to block the PVF debug engine when you debug a program.

Automatic Additions to Windows Firewall Exceptions List

When PVF is installed

If Windows Firewall is enabled when PVF is installed, certain components are automatically added to the Exceptions list. For PGI Visual Fortran, these components appear as follows:

  • Microsoft Visual Studio 2015/2013 (respectively)
  • PGI Debugger 2017

When PVF is uninstalled

If Windows Firewall is enabled when PVF is uninstalled, the components previously listed are automatically removed from the Exceptions list.

When using PVF to Debug

If the PVF Debug Engine components are not listed in the Exceptions list and Windows Firewall is enabled when you use PVF to debug, the Firewall displays a dialog that allows you to Unblock the PVF debug engine components. If you choose the Unblock option, Windows Firewall adds the component to its list of Exceptions and you do not see the pop-up dialog again unless you reinstall.

Tip: On rare occasions, this pop-up may prevent the debug session from starting correctly. If this occurs, use the Task Manager to end the debug session.
Note: You can manually add these components to the Windows Firewall list of Exceptions.

8.2. Troubleshooting

The most common installation problems are related to licensing.

To troubleshoot your installation, first check that the license.dat file you are using contains a valid license. Then, if you are using permanent node-locked licensing, check that the PGI License Server, a Windows Service, is started on the system that is providing the licensing.

Typical FLEX errors encountered may include the following:

  • Error: When starting the PGI License Server, a system message appears that states 'The PGI License Server service on Local Computer started and then stopped. Some services stop automatically if they have no work to do, for example, the Performance Logs and Alerts service.'

    Possible Solution: This message may appear because the license.dat file accessed by the FLEX License Manager does not contain a valid license or the license you have does not allow PGI License Server to run. Verify your PVF license is valid.

  • Error: When starting PGI Visual Fortran, a FLEXible License Manager dialog appears that states 'pvf: LICENSE MANAGER PROBLEM: No such feature exists.'

    Possible Solution: This message may appear because the license.dat file accessed by the FLEX License Manager does not contain a valid license. Verify your PVF license is valid.

  • Error: When starting PGI Visual Fortran, a FLEXible License Manager dialog appears that states 'pvf: LICENSE MANAGER PROBLEM: Cannot connect to license server system.'

    Possible Solution: This message may appear because the PGI License Server has not been started. Start the server manually, if necessary.

  • Error: When using a compiler or tool from the PVF command line, a message stating 'LICENSE MANAGER PROBLEM: Failed to checkout license' appears.

    Possible Solution: This message may appear because the PGI License Server has not been started. Start the server manually, if necessary.

8.3. Installation Errors to Ignore

Occasionally an installation produces one of the following error messages, or something similar. These errors do not interfere with proper installation and can safely be ignored.

9. Co-installation

This section describes how to co-install PGI command-line products with PGI Visual Fortran.

Co-installation of PGI command-line Products with PGI Visual Fortran

PGI compilers and tools can be co-installed with PGI Visual Fortran as long as the version of PGI Workstation being installed has the same or newer version than the version of PGI Visual Fortran.

Note: If it is necessary to install an older version of PGI Workstation on a system where PVF 17.10 has already been installed, uninstall PVF 17.10, install PGI Workstation, then re-install PVF.

Any version of PVF can be installed on a system where PGI Workstation has been installed.

10. Uninstalling PVF

To uninstall PVF, use the following guidelines:

  • Administrative privileges are required to uninstall.
  • Make sure that Visual Studio is not running when uninstalling PVF.
  • There are two components to PVF:
    • Compilers, tools, and libraries
    • Visual Studio integration components
    These components may be uninstalled separately, allowing users to maintain multiple versions of the compilers on their system. These components appear in the Control Panel | Add or Remove Programs dialog as follows:
    • PGI Visual Fortran (compilers only) 17.10
    • PGI Visual Fortran

  • The PVF install package requires but does not include a version of the Microsoft Windows SDK. PVF for Visual Studio 2015 requires the Windows 10 SDK; PVF for Visual Studio 2013 requires the Windows 8.1 SDK. These components appear listed in Add or Remove Programs under "Windows Software Development Kit" with specific version information.

  • If your installation of PGI Visual Fortran included installation of the Microsoft Visual Studio Shell, then several other components appear in the Add or Remove Programs dialog. The names of these components may appear slightly different on your system than they appear in the following list, depending on localization settings and whether the system is running a 64-bit operating system, and are similar to these:
    • Microsoft Visual Studio 2015 Shell (Integrated)
    • Microsoft Visual Studio 2015 Shell (Isolated)
    • Microsoft SQL Server 2012 Management Objects
    • Microsoft System CLR Types for SQL Server 2012
    • Microsoft Help Viewer 2.0
    • Microsoft .NET Framework 4.5 SDK
    • Microsoft .NET Framework 4.5 Multi-Targeting Pack
    • Microsoft .NET Framework 4.5
Note: Take care when uninstalling these components to ensure that no other software on the system depends on them. Further, always uninstall the Microsoft .NET Framework components last.

If there are problems while uninstalling PVF, try reinstalling the product, then uninstall again.
