I got this error while doing the Matrix Multiplication for two matrixes of
size 95x95.
I don't get any error if the matrix is say 95x55 and 55x95 or smaller than
this. I am running lam-7.0-67 version of Lam. And the cluster is made of
64-bit optron processors with Suse 64-bit Operating system.
I never had any problem with lam-6.5.4-1dyn version of lam on a different
cluster built out of Pentium 2 machines. There I am able to do the matrix
multiplication of up to 500x500.
MPI_Send: process in local group is dead (rank 0, MPI_COMM_WORLD) Rank (0,
MPI_COMM_WORLD): Call stack within LAM: Rank (0, MPI_COMM_WORLD): -
MPI_Send() Rank (0, 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 14236 failed on node n12 (192.168.1.113) with exit status 1.
