Removal of OpenMPI Modules on ASPIRE 2A

/in , /by

Dear Users,

The following OpenMPI modules will be removed from ASPIRE 2A on 3 February 2025:

openmpi/4.1.4-aocc4.0

openmpi/4.1.5-aocc4

openmpi/4.1.5-gcc11

openmpi/4.1.5-icc22

openmpi/4.1.5-icc24

These modules were built statically, and following the update of PBS to a newer version, they no longer function correctly across multiple nodes. While MPI processes can still be spawned within a single compute node, these modules fail to communicate across nodes. As a result, applications built with these versions of OpenMPI will not run successfully on multiple nodes.

To ensure continuity in your workflows, we recommend transitioning to the following OpenMPI versions:

openmpi/4.1.2-hpe(default)

openmpi/4.1.6-gcc11

openmpi/4.1.7-gcc11

openmpi/4.1.7-icc24.2.1 

openmpi/5.0.5-gcc11

openmpi/5.0.5-icc24.2.1 

If you encounter any issues while using these versions, please do not hesitate to contact our helpdesk via the Service Desk Portal or email us at [email protected].

Thank you for your understanding and cooperation.

Warm regards,

NSCC Team
