Blue Waters partners;
As announced back in December, the version defaults for the 4 programming environments (cray, gnu, intel and pgi) have been changed to newer versions as of 1/23/2020. A table with the changes is available at /pe-updates#pe18.12. Note that gcc moved from 4.9.3 to 6.3.0 which can impact C++ codes and libraries.
For users who wish to continue with the older GNU compiler please use PrgEnv-gnu/5.2.82-gcc.4.9.3 as in:
$ module unload PrgEnv-cray/5.2.82
$ module load PrgEnv-gnu/5.2.82-gcc.4.9.3
and then select the older modules listed in the table at /pe-updates#pe18.12.
Statically linked applications should continue to run without needing to be recompiled. Execution of dynamically linked applications should be checked. You can use the ldd command to check the linkage model your executable. Monitor your jobs already in the queue.
If you encounter issues while testing the new environments please send email to help+bw@ncsa.illinois.edu.

To prepare for the change we have provided metamodules to make your environment close to what the defaults will be.To test the new programming environments please follow the instructions provided at /pe-updates#pe18.12. Some known issues are documented as well.
