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

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, 8.000, 9.000 or 10.2 in it. This is the highest release this license will support. Currently, you should have a 9.000. To use the newest release, you will need to retrieve updated license keys for 10.0. Note: Any release prior to the value in the field should work with the license.

How do I find out if I qualify for a current release 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 9.0-1, for example, you will also qualify for 9.0-2, 9.0-6, and so on when/if they occur but this may change in a future release.

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.
