Hi,
We are using OpenMPI 1.1.1 and need Multiple Thread support. OpenMPI is
configured with these options (the /opt mount point is on the head node
and is visible to all nodes):
--prefix=/opt/openmpi
--with-tm=/opt/torque
--with-devel-headers
--with-threads=posix
--enable-mpi-threads
--enable-progress-threads
When I run a program (even a simple one) on more than just the head
node, it either 1) hangs on the MPI_Init and does nothing or 2) outputs
the error message "[*:29246] mca_btl_sm_component_init: mkfifo failed
with errno=17" (where * is the machine name). Everything builds fine
(using mpic++) and runs fine (minus multithread support) if I configure
and build OpenMPI without multithread support.
I've tried to search for help on this, but all I could find is one
message (for 1.0.2) asking for help with no replies
(http://www.open-mpi.org/community/lists/users/2006/06/1350.php). Does
anyone have any idea what might be going on? Or any suggestions as to
what to try? I've included my ompi_info output just in case...
Thanks,
Matt
