All,
I currently run lam-mpi on small commodity clusters. I use lam-mpi with
ifort 9.1.3 for compiling and running fortran 90 fluid dynamics codes.
I have been running on AMD 2500+ (32bit), P4 (32bit), and AMD 3200+ (64bit)
nodes single core without any problems, but when I upgraded to running on
AMD 4600+ dual core nodes and Core2Duo e6400 dual core nodes I get the error
below after an arbitrary number of iterations. Has anyone had any similar
problems using lam-mpi with ifort on these processors? If so have they had
any luck addressing the problem?
Thanks,
-DR

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.
