- Fortran 2003 ISO_C_BINDING—The ISO_C_BINDING module is partially implemented. The BIND attribute is supported for derived types and constant kind definitions are provided that map to C types. For procedures, the VALUE and BIND attributes are supported, as well as the BIND attribute for global data. The procedure C_LOC is supported, which returns the C address of an object. Other procedures in ISO_C_BINDING, such as C_ASSOCIATED, are not yet implemented.
- Fortran 2003 Allocatable Regularization—Fortran 2003 allocatable regularization is implemented in PGF95 and is always enabled. These changes allow allocatable arrays to be passed as dummy arguments, to be returned from functions, and to be components of derived types.
- Fortran 2003 Allocatable Array Assignment—Fortran 2003 allocatable array assignment is available in PGF95. The default is to use the Fortran 95 assignment semantics; however, the option -Mallocatable=03 enables the Fortran 2003 assignment semantics.
- Fortran 2003 Asynchronous Input/Output—Fortran 2003 asynchronous I/O is partially implemented in PGF77 and PGF95 compilers. For external files opened with ASYNCHRONOUS='YES in the OPEN statement, asynchronous I/O is allowed for external files opened with ASYNCHRONOUS='YES' in the OPEN statement. Asynchronous I/O operations are indicated by ASYNCHRONOUS='YES' in READ and WRITE statements. The compilers do not implement the ASYNCHRONOUS attribute or ASYNCHRONOUS statement.
- Fortran 2003 Stream Input/Output—Fortran 2003 Stream access I/O is implemented.
- -Mallocatable=[95|03]—The -Mallocatable option controls how the compiler treats assignment of allocatables. The default behavior is to use Fortran 95 semantics; the 03 option instructs the compiler to use Fortran 2003 semantics.
The license file will have a field with 3.000, 3.100, 3.200, 3.300, 4.000, 4.100, 5.000, 5.100, 5.200, 6.000, 6.100, 6.200, 7.000, 7.100, 7.200 or 8.000 in it. This is the highest release this license will support. Currently, you should have a 7.200. To use the newest release, you will need to update your license keys for 8.0. Note: Any release prior to the value in the field should work with the license.
The subscription information is summarize on your PIN management page. Click a PIN for account information including subscription expiration, release number and current license keys. Note: If you qualify for release 8.0-1, for example, you will also qualify for 8.0-2, 8.0-6, and so on when/if they occur.
The PGI Subscription Service entitles the subscriber to new licenses for new releases. Typically, a subscription is valid for one year from date of purchase. New license purchases include 60 days of subscription service. If you did not purchase a subscription when you purchased your license, or if your subscription has expired, you can qualify for the current relase by bringing your subscription current. You may also wish to read the PGI Subscription Service Agreement.
- The 8.0 uses a new type of license file, and this will require using the 11.5 version of pgroupd. Make changes to your lciense server, in order for the 8.0 license file to support older releases as well.
- The 8.0 release, currently available in the download section will now support SUSE 11.0, Red Hat Enterprise Linux 5.2, and Fedora Core 9, for 64-bit on AMD64 or EM64T.
- The current release supports quad-core AMD Shanghai and the latest multi-core Intel systems.
- The current release has no limit on the number of threads an OpenMP supports.
The current release supports module load builds, a style of program
compilation and linking (like makefiles) that some sites have requested
(note: do not confuse this with Fortran 95 modules). Those sites can
download and will know how to edit and install the
Module TCL script
as file 8.0 in a directory named pgi so that
module load pgi/8.0works as expected.
- Further information can be found in the 8.0 Release Notes located in the documentation section.
- 32-bit executables that use libpthreads may fail on 64-bit Linux systems because libpthreads reduces stack size to 2MB. This is a Linux limitation. libpthreads is used by routines compiled -mp or -Mconcur. 64-bit executables do not experience this limitation.
- Some users linking with libpthreads (-mp or -Mconcur) have seen the error message symbol _h_errno, version GLIBC_2.2.5 not defined in file libc.so.6 with link time reference This can be worked around with the environment variable LD_ASSUME_KERNEL export LD_ASSUME_KERNEL=2.4.1 or export LD_ASSUME_KERNEL=2.2.5 for example.
