[gmx-users] Signal 11 error with parallel runs

[sophie.vilarem@laposte.net]

Hi everybody,

I am trying to run the d.poly-ch2 benchmark, on a dual xeon
cluster.
I have installed the latest LAM version of MPI, and the latest
version of Gromacs.
It works all right on 1 CPU, but it fails on 2 CPUs (or
more...) with the following error :

...
MPI_Send: process in local group is dead (rank 1, MPI_COMM_WORLD)
Rank (1, MPI_COMM_WORLD): Call stack within LAM:
Rank (1, MPI_COMM_WORLD):  - MPI_Send()
Rank (1, MPI_COMM_WORLD):  - MPI_Sendrecv()
Rank (1, MPI_COMM_WORLD):  - main()
-----------------------------------------------------------------------------
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 8399 failed on node n0 (10.10.100.5) due to signal 11.


Can anybody help me please? I'm stuck!
Thank you very much...
