I've tried with Thread support: posix (mpi: yes, progress: no), using MPI_THREAD_MULTIPLE and MPI_THREAD_SINGLE and these all hang as well. Unlike Arnstein I do not find that jobs will work properly running on a single node. Hugh On Tue, 25 Oct 2005, Jeff Squyres wrote: Hugh -- We are act

Hi, I'm getting the same hangs in my environment and will contribute my findings. The info from ompi_info, debug output and application source is attached. When running on one machine and two processes like this: mpirun -np 2 -mca orte_debug 1 mpitest The application successfully executes a

It's still only lightly tested. I'm surprised that it totally hangs for you, though -- what is your simple test program doing? It just initializes mpi (tried both mpi_init and mpi_init_thread), prints a string and exits. It works fine without thread support compiled into ompi. It happens w

Howdy, I tried installing the release candidate with thread support enabled ( --enable-mpi-threads and --enable-progress-threads ) using an old rh7.3 install and a recent fc4 install (Intel compilers). When I try to run a simple test program, the executable, mpirun and orted all sleep in wh
