What version of LAM are you using? This does not cause a problem for
me. For example:
[16:57] eddie:~/mpi % cat hello.c
#include <stdio.h>
#include <mpi.h>
#include <stdlib.h>
int main(int argc, char **argv)
{
int rank = 0, size = 0;
char hostname[BUFSIZ];
MPI_Init(&argc, &argv);
MPI_Comm_rank(MPI_COMM_WORLD, &rank);
MPI_Comm_size(MPI_COMM_WORLD, &size);
gethostname(hostname);
printf("Hello, world! I am %d of %d (argv: %s)\n", rank, size,
argv[1]);
MPI_Finalize();
return 0;
}
[16:57] eddie:~/mpi % mpicc hello.c -o hello
[16:57] eddie:~/mpi % mpirun -np 2 hello hfoo
Hello, world! I am 0 of 2 (argv: hfoo)
Hello, world! I am 1 of 2 (argv: hfoo)
[16:57] eddie:~/mpi % mpiexec -np 2 hello hfoo
Hello, world! I am 1 of 2 (argv: hfoo)
Hello, world! I am 0 of 2 (argv: hfoo)
