I can't say anything regarding the Condor integration of Open MPI, but starting it directly by mpirun and supplying a valid number of ranks and hostfile should start some processes on other machines as requested. Can you run a plain mpihello first and output rank and hostname? Do you have ssh access to all the machines in questions? You have a shared home directory with the applications? -- Reuti > when I ran mpirun from a machine and checking the memory status for the three > machines that I have it appear that the memory usage increased just in the > same machine. > > Regards, > > > From: re...@staff.uni-marburg.de > > Date: Wed, 28 Mar 2012 15:12:17 +0200 > > To: us...@open-mpi.org > > Subject: Re: [OMPI users] Can not run a parallel job on all the nodes in > > the cluster > > > > Hi, > > > > Am 27.03.2012 um 23:46 schrieb Hameed Alzahrani: > > > > > When I run any parallel job I get the answer just from the submitting node > > > > what do you mean by submitting node: you use a queuing system - which one? > > > > -- Reuti > > > > > > > even when I tried to benchmark the cluster using LINPACK but it look like > > > the job just working on the submitting node is there a way to make > > > openMPI send the job equally to all the nodes depending on the number of > > > processor in the current mode even if I specify that the job should use 8 > > > processor it look like openMPI use the submitting node 4 processors > > > instead of using the other processors.
