  Hello,nI have a running Ansys (ARC) Cluster environment. However, what I would like to do, to assign 1 (or 2 if necessaire) nodes to a single dual socket server and assign each to one NUMA node.nWhy? I remarked that jobs have a significant performance improvement when not shared accross multiply CPUs.nWhats the problem?nI can limit the used CPUs of each node, but I haven't found a way yet, to make Ansys NUMA aware. Is this possible and if how?.Thanks in advance,nnBest Regards,nnLukasn

  It's not true that jobs have a significant performance improvement when not shared accross multiply CPUs.. nARC is s simple basic job scheduler, doesn't have such advanced feature to detect NUMA. Turn to other 3rd party job scheduler if possible. nIt's possible to let Intel MPI to run a job on NUMA node. n
