Good morning. I'm experiencing some problems with Open MPI 1.4.2, built on a CentOS 5.5, on a 32 bit machine.
I've configured it with ./configure --prefix=/usr/local/openmpi --enable-debug --enable-memchecker --enable-heterogeneous When I run "/usr/local/openmpi/bin/mpiexec -np 3 ls", Open MPI crashes with this error message: -------------------------------------------------------------------------- It looks like opal_init failed for some reason; your parallel process is likely to abort. There are many reasons that a parallel process can fail during opal_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): opal_memchecker_base_select failed --> Returned value -13 instead of OPAL_SUCCESS -------------------------------------------------------------------------- [ccdestefanolinux:06037] [[INVALID],INVALID] ORTE_ERROR_LOG: Not found in file ../../orte/runtime/orte_init.c at line 77 [ccdestefanolinux:06037] [[INVALID],INVALID] ORTE_ERROR_LOG: Not found in file ../../../../orte/tools/orterun/orterun.c at line 543 It seems that the memchecker does not work, because after reconfiguring without "--enable-memchecker" and rebuilding, I don't receive the same error anymore. May any of the Open MPI developers verify this problem, please ? Thank you very much.
