Surely this is the problem of the scheduler that your system uses,
rather than MPI?

It works after creating a new pe and even from the command prompt with out
using SGE.

Hello,
I wonder if someone can help.
The situation is that I have an MPI-parallel fortran program. I run it
and it's distributed on N cores, and each of these processes must
call an external program.
This external program is also an MPI program, however I want to run it
in serial, on the co

Correct, i was not clear. It spawns more than 7 processes per node. (It spawns
8 of them).

When you say "it fails", what do you mean? That it doesn't run at all, or
that it still fills each node, or...?

Hello All.
I am trying to run a parallel application that should use one core less than
the no of cores that are available on the system. Are there any flags that i
can use to specify this.
i tried using the following syntax with machinefile
openmpi-1.4-BM/bin/mpirun -np 14 -npernode 7 -machine

Hello,
Yes, I compiled OpenMPI with --enable-heterogeneous. More precisely I
compiled with :
$ ./configure --prefix=/tmp/openmpi --enable-heterogeneous
--enable-cxx-exceptions --enable-shared
--enable-orterun-prefix-by-default
$ make all install
I attach the output of ompi_info of my 2 machines.
Did you configure Open MPI with --enable-heterogeneous?

Hi,
I've recently been trying to develop a client-server distributed file
system (for my thesis) using the MPI. The communication between the
machines is working great, however when ever the MPI_Comm_accept()
function is called, the server starts like consuming 100% of the CPU.
One interest
I found the problem - the orted wasn't whacking any lingering session
directories when it exited. Missing one line...sigh.
Rolf: I have submitted a patch for the 1.4 branch. Can you please review? It is
a trivial fix.
David: Thanks for bringing it to my attention. Sorry for the problem.
Ralph
