Hi, I just upgraded from the default ompi install on OS X 10.6 to v1.5.3 so that I can use the processor affinity options. However there seems to be some trouble. My mpi application executes perfectly with the following CL statement: /usr/local/openmpi-1.5.3/bin/mpiexec --host `hostname` --np 2 *APPLICATIONANDARGS* but this fails: /usr/local/openmpi-1.5.3/bin/mpiexec --host `hostname` --np 2 --cpus-per-proc 2 *APPLICATIONANDARGS* saying: -------------------------------------------------------------------------- An attempt to set processor affinity has failed - please check to ensure that your system supports such functionality. If so, then this is probably something that should be reported to the OMPI developers. -------------------------------------------------------------------------- -------------------------------------------------------------------------- mpiexec was unable to start the specified application as it encountered an error:
Error name: No such file or directory Node: hrle03274.<BASEURLNAME DELETED> when attempting to start process rank 0. -------------------------------------------------------------------------- 2 total processes failed to start this also fails: /usr/local/openmpi-1.5.3/bin/mpiexec --host `hostname` --np 2 --bind-to-core *APPLICATIONANDARGS* saying the exact same thing. I configured the install with: ./configure --with-hwloc=internal --prefix=/usr/local/openmpi-1.5.3/ any help in getting this working would be greatly appreciated as the process jumping from core to core is killing my system responsiveness. Thanks, Karl
