How do I find out if my license will work with the current release?

Previously, a PGI license file had 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, 8.000, 9.000 or 10.2 in it. This number represents the highest release this license will support along with all previous releases. (Note: Since 7.0, licenses are compatible with releases back to 5.1—older releases may need the older license format).

With the PGI 2010 release version 10.3, PGI license files use a form of your subscription expiration date as the release number. These licenses will work with any software that is issued before this expiration date. For example, a license with a subscription expiration date of December 25, 2010, will include "2010.1225" as the version in the license.dat file. A new release issued for example on June 9, 2010, (and called version 10.6), will have a release version date of 2010.0609. Because the software release version date is less than the formatted subscription expiration date contained in the license, this software will work. Old releases also work with a new license format because their release version "date" (e.g. 7.200) is also before the subscripton expriration date of 2010.1225.

How do I find out if I qualify for a current release license?

Your subscription information is summarized on your PIN management page. Click any PIN in the list for information about that PIN including subscription expiration date, release number and current license keys. Note that current release licenses use the expiration date of the subscription as the date of the newest release the license will support. If your subscription is current you will not need to generate a new license for a new release. A release for example, 10.5, which came out May 8, 2010, has a release version date of 2010.0508. A license with subscription expiration date of June 14, 2011, will have a license with a FEATURE or PACKAGE line value of 2011.0614. This license should work with the 10.5 release, along with all releases that are issued on or before June 14, 2010.

What is a subscription?

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.

How does this release differ from the previous release?

  • PGI 2010 uses a new type of license file that requires using the 11.7 version of pgroupd. You will need to make changes to your license server to allow the 10.2 license file to support older releases as well.
  • PGI 2010 now supports up to 256 OpenMP threads. Earlier versions had a 64 thread limit.
  • Further information can be found in the PGI 2010 Release Notes located in the documentation section.

Any known problems with the recent releases?

  • 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.
