When you want to run on Fidis and its Gacrux extension
Both types of nodes are accessible from the Fidis frontend (
|408 compute nodes|
Infiniband FDR fully-non-blocking connectivity with a fat-tree topology
216 compute nodes
The nodes are arranged in non-blocking groups of 24 and the “Skylake" architecture offers significantly increased memory bandwidth.
Running on Gacrux
Please note that to make use of the new AVX-512 instructions your codes will need to be recompiled. The centrally provided codes and libraries available through modules have been optimised for the new architecture.
Running on the Fidis nodes
If you wish to use only the Fidis nodes then please specify:
Running on the Gacrux nodes
If you wish to specifically ask for Gacrux nodes then please use the following SLURM directive:
If you do not specify a constraint then jobs may run on either partition but they will never span different architectures.
Two Gacrux nodes and two Fidis nodes are available for compiling codes via the build partition
