Theta will be unavailable from Monday, July 11, to Wednesday, July 13, 2022, while we upgrade the system software and programming environment (PE). This will include updating the default PE to 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. It is strongly recommended for users to 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.
Since PE versions older than 21.05 will no longer be supported, if there are any requirements for specific and deprecated (from the PE perspective) libraries that your code absolutely needs, we recommend you copy them to your project directory.
To compare the list of packages in 20.06 (current default) and 21.09 (new default next month), see: https://www.alcf.anl.gov/sites/default/files/2022-06/Theta_PE_Diff.ods
