Hi jeff,
  Thanks, i have installed openMPI with the threads enabled option as per the 
readme file of openmpi. (alpha 7 of openmpi1.1)

  Hi have a problem with mpirun.

  1)When there is no relevant executable present on the remote node where  i 
want to launch the mpi process, mpirun just hangs without any error  message. 
Shall i interpret it as no executable present?once i copy the  executable to 
that node, it proceeds fine. Why no error message is  given by mpirun, as in 
lam, no file found etc..

  2)when i launch many processes , oversubscribe a node heavily, it  hangs. 
Neither error message, nor i cant do kind.  For example a  simple broadcast 
where each process executes a bcast call, with   110 processes per node.(My 
p4,256MPB ram,tcp network) ,it just hangs. 

  3)sometimes, for the same program with 45 process, it says 4 were killed 
automatically.

  I am afraid, at times. Anything wrong with my program or mpirun has some 
problem.?

  Regards,
  Imran

questions from the LAM list, I think you are actually asking how to get   
support for MPI_THREAD_MULTIPLE (which will include pthread support on Linux   
systems).

  Use   the --enable-mpi-threads option to configure to enable support for   
MPI_THREAD_MULTIPLE (please see the README file for more details).  Per the   
warning from my previous mail 
(http://www.open-mpi.org/community/lists/users/2006/05/1309.php),   this 
support is only partially implemented and tested.

Thanks,
