Hello,
I have a problem with commercial code of LSDYNA when I use it with lam/mpi.
I have 6 nodes (bi-processor 2000+ with 2 Go memory). The distribution
is debian sarge with a 2.6.12 kernel.
I run lam 7.0.3 (recon -v et lamboot -v) and I launch some programs with
mpirun :
- a small program works fine on all node (C code made by me) :
clement_at_mefmaster:~/mpi$ /opt/lam/703/bin/mpirun N
/home/clement/mpi/test-mpi
mefnode1 : je suis la node numéro 1 !!
mefnode2 : je suis la node numéro 2 !!
mefmaster : je suis la node numéro 0 !!
- a lsdyna calcul works on one node :
clement_at_mefmaster:~/mpi$ /opt/lam/703/bin/mpirun -np 1
/home/clement/mpi/mppdyna/mpp971_d_7600.2.1077_ia32_linux_lam703
i=/home/clement/mpi/mppdyna/impact.dyn

on UNIX computers note the following change:
ctrl-c interrupts ls-dyna and prompts for a sense switch.
type the desired sense switch: sw1., sw2., etc. to continue
the execution. ls-dyna will respond as explained in the users manual
type response
----- ------------------------------------------------------------
sw1. a restart file is written and ls-dyna terminates.
sw2. ls-dyna responds with time and cycle numbers.
sw3. a restart file is written and ls-dyna continues calculations.
sw4. a plot state is written and ls-dyna continues calculations.
sw5. ls-dyna enters interactive graphics phase.
swa. ls-dyna flushes all output i/o buffers.

One of the processes started by mpirun has exited with a nonzero exit
code. This typically indicates that the process finished in error.
If your process did not finish in error, be sure to include a "return
0" or "exit(0)" in your C code before exiting the application.
PID 18959 failed on node n0 (172.20.5.212) due to signal 11.

I have run with different version of lsdyna, I have recompiled mpi and
lam many times with different versions.
Do you have any idea to solve my problem?
Thanks in advance.
