I have no idea what this is trying to tell me. Help? jhammond@nid00024:~/MPI/qoit/collectives> mpirun -n 2 ./driver.x 64 [nid00024:00482] [[46168,0],0] ORTE_ERROR_LOG: Not found in file ../../../../../orte/mca/plm/alps/plm_alps_module.c at line 418
I can run the same job with srun without incident: jhammond@nid00024:~/MPI/qoit/collectives> srun -n 2 ./driver.x 64 MPI was initialized. This is on the NERSC Cori Cray XC40 system. I build Open-MPI git head from source for OFI libfabric. I have many other issues, which I will report later. As a spoiler, if I cannot use your mpirun, I cannot set any of the MCA options there. Is there a method to set MCA options with environment variables? I could not find this documented anywhere. In particular, is there a way to cause shm to not use the global filesystem? I see this issue comes up a lot and I read the list archives, but the warning message ( https://github.com/hpc/cce-mpi-openmpi-1.6.4/blob/master/ompi/mca/common/sm/help-mpi-common-sm.txt) suggested that I could override it by setting TMP, TEMP or TEMPDIR, which I did to no avail.
