Hi everyone,
I've created a 2 node cluster running FC8. I've installed MPICH2
1.0.6pl on both (not NFS'd).
The Master, Ragnar, is a 64 bit; olaf is a 32 bit.
I set up the ring, and mpdtrace shows:
$ mpdtrace -l
Ragnar_37601 (192.168.0.2)
olaf_45530 (192.168.0.5)
$
I run a VERY simple MPI program and it hangs:
#include "mpi.h"
#include <stdio.h>
#include <math.h>
#include <string.h>
int main( int argc, char *argv[] )
{
MPI_Init(&argc,&argv);
printf("Hello!\n");
MPI_Finalize();
return 0;
}
The program outputs the two lines for the two nodes and hangs. I have to
CNTRL-C out of it:
[EMAIL PROTECTED] ~/BEOAPPS]$ mpiexec -l -n 2 mpibase
0: Hello!
1: Hello!
It would sit there forever if I didn't bail. Other simple tests work fine:
Running a simple "hostname" test works fine:
$ mpiexec -l -n 2 hostname
0: Ragnar
1: olaf
$
Now I run a Hello World (no MPI):
#include <stdio.h>
#include <math.h>
int main(int argc,char *argv[])
{
printf("\nHello World!\n %d \n", n);
}
$ mpiexec -l -n 2 ../HelloWorld
0:
0: Hello World!
1:
1: Hello World!
$
Any help with this would be appreciated
Gregg
