Re: [OMPI users] Can't get OPENMPI to run parallel job with Myrinet/GM

Tom,

Here is how I configured Open MPI. It's mostly the default configuration ...

../../ompi-trunk/configure --prefix=/nfs/home/bosilca/opt/unstable/fog/ fast --disable-debug --enable-picky --with-platform=optimized -- disable-mpi-cxx --disable-mpi-f90 --enable-mpi-f77 --disable-mpi- profiling --with-gm=/opt/gm -enable-visibility

No specific arguments were required to run the tests. You can force the GM BTL by using "--mca btl gm,self" or "--mca btl gm,sm,self" if you need shared memory.

Would you be able to send me the mpirun command and args that you use?

how can I get more output to study? I added "--display-map -d -v " to my

mpirun command, which gives more output, but not the reason for the
failure.

I run a full testing on the GM with 1.2.5 and with the trunk. Both of
them run to completion without any errors.

Moreover, the error message only say that one of the processes was
terminated, which usually means that something bad happened somewhere
else, and the runtime decided to terminate the whole job. This might
be a segfault, an abort. Without more information it will be difficult
to help or to offer any advice..

I am trying to use openmpi 1.2.5 (I also tried 1.2.4) to run a
parallel job
using GM drivers.  The only message I get is:

mpirun noticed that job rank 0 with PID 19508 on node node93 exited on

signal 15 (Terminated).

I can run serially on one node (4 processors), it just dies when
trying to use
more than one node.

Any help appreciated.
