Helix/Migration Guide

List of important changes on bwForCluster Helix for users of the previous system bwForCluster MLS&WISO.

1 CPU manufacturer

The CPU manufacturer has changed from Intel to AMD. All compute nodes are now equipped with the same AMD processors. It is recommend that you newly compile your applications.

2 Software Modules

The software module system is now based on lmod and MPI modules are provided in a hierarchical manner:

• You need to load a compiler module first to see suitable MPI modules with 'module avail' and to load MPI modules.
• 'module spider' shows all available MPI modules.

5 Access to SDS@hd

You can access your storage space on SDS@hd directly in /mnt/sds-hd/ on all login and compute nodes. Kerberos tickets are no longer needed.
