DAPL startup: RLIMIT_MEMLOCK too small Error

I am trying to execute my code on 25 processors using intel mpi.  I am using  intel parallel_studio_xe_2016_update2 cluster edition. Even after setting the maximum lock memory to unlimited  I am getting "DAPL startup: RLIMIT_MEMLOCK too small Error" error. I am herewith attaching the snapshots of the output of  ulimit -a  for master node and two computational nodes as well as the error.499923

Thanks,

Akhilesh

Hi Akhilesh,

Could you please create a simple shell script calling ulimit -a and use it as the target for mpirun, in order to confirm that all ranks would receive the required user limits?

Best regards,

Michael
