Hello Barry,
I am guessing you are trying to use a threaded build of Open MPI...
Unfortunately, the threading support in Open MPI 1.2.x is not only not well
tested, it has many known problems. We do not advise use of threading in
the Open MPI 1.2.x series. We even added a warning in version 1.2.

Dear Barry and Jeff,
using OpenMPI we are experimenting something like the behaviour reported
by Barry.
Let me to introduce the context:
we are using RHEL4 U4 on 2 way, AMD Opteron dual core, nodes.
Each node is equipped with 16 GB of RAM, plus 4 GB of SWAP.
OpenMPi is 1.2.2.
Sometimes, for jo

Could you check what apps are still running when it hangs? I.e., I
assume that all the uptime's are dead; are all the orted's dead on the
remote nodes? (orted = our helper process that is launched on the
remote nodes to exert process control, funnel I/O back and forth to

Hello,
The following command
mpirun -np 2 -hostfile ~/hostfile uptime
will occasionally hang after completing. The expected output appears on
the screen, but mpirun needs a SIGKILL to return to the console.
This has been verified with OpenMPI v1.2.4 compiled with both icc 9.1
