hi
my system's CPU is core i7.
I have run some cases in parallel processing mode in openfoam version 2.1.1 on cae linux OS successfully.
but I can not do that in openfoam version 2.3.1 on openSUSE distribution.
for example this error appeared for cavity case:


dc@linux-37pc:~/Desktop/cavity> mpirun -np 4 icoFoam -parallel
--------------------------------------------------------------------------
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_shmem_base_select failed
--> Returned value -1 instead of OPAL_SUCCESS
--------------------------------------------------------------------------
--------------------------------------------------------------------------
It looks like orte_init failed for some reason; your parallel process is
likely to abort. There are many reasons that a parallel process can
fail during orte_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_init failed
--> Returned value Error (-1) instead of ORTE_SUCCESS

(pre!)thank you for the help!
