Helix/Migration Guide

Here you can find a list of important changes on bwForCluster Helix compared to 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 MPI modules are now provided in a hierarchical manner. That means:

• 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.

3 Batch System

Queues:

• The single queue now contains all node types, also GPU nodes.
• The multi queue for CPU nodes is now named cpu-multi.

4 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.
