      Hello All,

      I have just setup a HPC (2 machines) with CentOS 7 (Distributed Memory Parallel) and I find an error when I execute the mpitest program.

      [ ]$ /usr/local/ansys_inc/v195/ansys/bin/mpitest -machines ladon:2:nodo01:2

      forrtl: severe (168): Program Exception - illegal instruction

      I have followed the "Linux_Installation_Guide for Ansys195". The files .hosts, machines and hosts195.ans are OK!

      Both machines have Selinux and Firewalld desactivated.

      I have also setup ssh without password.

      The installation folder are shared with NFS and the network is Infiniband Mellanox (100 Gb/s)

      Could you please help us?. Thanks.!!..

      Can you verify that all of the prerequisites are installed?
