Hi Daniel,
If you are really using LAM I suggest you move to OpenMPI, it's successor project. The LAM developers have all moved on a few years ago and LAM is no longer actively supported.
Cheers,
Mac (at the lake)

Subject: LAM: Problems to run the NAS MPI Benchmarks
Hi,
I'm a researcher of PUC Minas in Brazil and I'm trying to run some Benchmarks of NASA to my project here. But, when i use the make command for 4 procs in class A, a problem appears:
labadm_at_PSGLABPES10011:~/Documentos/Benchmarks/NPB3.2/NPB3.2-MPI/IS$ make NPROCS=4 CLASS=A
