Hi,
under which circumstances does LAM throw an error message like this:
---snip---

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 5096 failed on node n4 with exit status 1.

"Cannot allocate memory"is obvious. But on a node with 2GB RAM, no other
procs, and a local matrix size of 142MB? LAM version is 6.5.9, taken from
SuSE Linux 8.2. The failing program is used for parallel matrix setup and
decomposition using BLACS and ScaLAPACK on a 16-node P4 cluster system.
Any comments appreciated.
Regards,
Michael
