I know that it should be uncommon but why I get an error while I try to run a "parallel" application with only one process?
aopclf:ping fialho$ mpirun -np 1 ./ping [Fialho-2.local:02834] OPAL dss:unpack: got type 32 when expecting type 9 [Fialho-2.local:02834] [[57446,1],0] ORTE_ERROR_LOG: Pack data mismatch in file ../../../../orte/mca/grpcomm/base/grpcomm_base_modex.c at line 330 [Fialho-2.local:02834] [[57446,1],0] ORTE_ERROR_LOG: Pack data mismatch in file ../../../../../orte/mca/grpcomm/bad/grpcomm_bad_module.c at line 444 aopclf:ping fialho$ I understand the error and I know the reason, but this is a limitation from Open MPI (due to modex?) or from the MPI standard?
