Hi Mathan,

Before you start to try anything on this cluster, please note that ...

Yade is parallelized with OpenMP, which can be used on shared memory systems (like single workstations with N cpu cores). It will definitely not work on a distributed memory system (like the most of HPCs are)! There you should look to another DEM code, which is parallelized with MPI... I think ESys is MPI based, not sure ...
If SGI Altix ICE 8400 EX is a shared memory system,  you can try to run yade on it. 
Otherwise you can use yade only on one node!

cheers,

christian
