I can only make a statement for SGE that it would honor the group id for the "built-in method" or "rsh startup method" with SGE's patched rshd, not for ssh. But you are using Torque I assume, as there is no -W switch in SGE. How did you build Open MPI then? I thought the support for Torque is available by default without any special switch to configure in Open MPI. So, if the slave tasks are started by the pbs_mom, then it should also get the set group id. As I don't use Torque I can't make any definite statement for it. Are you resetting inside the job script some variables to let it run outside Torque, i.e. without tight integration? -- Reuti > -----Original Message----- > From: users-boun...@open-mpi.org [mailto:users-boun...@open-mpi.org] On > Behalf Of Reuti > Sent: Wednesday, September 07, 2011 12:24 PM > To: Open MPI Users > Subject: Re: [OMPI users] Can you set the gid of the processes created by > mpirun? > > Hi, > > you mean you change the group id of the user before you submit the job?
