Update to the Default Theta Programming Environment (PE)

Theta will undergo system upgrades next month that will update the default programming environment (PE) to version 21.09. All programming environments lower than 21.05 are no longer supported and will be removed from the system, including the current default (20.06). We strongly recommend that users rebuild their codes against the latest PE (21.09) ahead of the change next month. The latest PE (21.09) can be found at /opt/cray/pe/perftools/21.09.0.
