Dear OpenMPI users and developers, I'm using IBM Spectrum MPI 10.1.0 based on OpenMPI, so I hope there are some MPI expert can help me to solve the problem.
When I run a simple Hello World MPI program, I get the follow error message: A requested component was not found, or was unable to be opened. This means that this component is either not installed or is unable to be used on your system (e.g., sometimes this means that shared libraries that the component requires are unable to be found/loaded). Note that Open MPI stopped checking at the first component that it did not find. Host: openpower Framework: pml Component: pami -------------------------------------------------------------------------- -------------------------------------------------------------------------- It looks like MPI_INIT failed for some reason; your parallel process is likely to abort. There are many reasons that a parallel process can fail during MPI_INIT; some of which are due to configuration or environment problems. This failure appears to be an internal failure; here's some additional information (which may only be relevant to an Open MPI developer): mca_pml_base_open() failed --> Returned "Not found" (-13) instead of "Success" (0) -------------------------------------------------------------------------- *** An error occurred in MPI_Init *** on a NULL communicator *** MPI_ERRORS_ARE_FATAL (processes in this communicator will now abort, *** and potentially your MPI job) My sysadmin used official IBM Spectrum packages to install MPI, so It's quite strange that there are some components missing (pami). Any help? Thanks -- Ing.
