Hello,

I am using Sun HPC Toolkit 7.0 to compile and run my C MPI programs.

I have tested the myrinet installations using myricoms own test programs.
The Myricom software stack I am using is MX and the vesrion is
mx2g-1.1.7, mx_mapper is also used.
We have 4 nodes having 8 dual core processors each (Sun Fire v890) and
the operating system is
Solaris 10 (SunOS indus1 5.10 Generic_125100-10 sun4u sparc
SUNW,Sun-Fire-V890).

The contents of machine file are:
indus1
indus2
indus3
indus4

The output of *mx_info* on each node is given below

MX Version: 1.1.7rc3cvs1_1_fixes
MX Build: @indus4:/opt/mx2g-1.1.7rc3 Thu May 31 11:36:59 PKT 2007
2 Myrinet boards installed.
The MX driver is configured to support up to 4 instances and 1024 nodes.

Do you have any suggestion or comments why this error appear and whats
the solution to this problem. I have checked community mailing list for
this problem and found few topics related to this, but could find any
solution. Any suggestion or comments will be highly appreciated.

The code that i m trying to run is given as follows:

#include <stdio.h>
#include "mpi.h"
int main(int argc, char **argv)
{
  int rank, size, tag, rc, i;
  MPI_Status status;
  char message[20];
  rc = MPI_Init(&argc, &argv);
  rc = MPI_Comm_size(MPI_COMM_WORLD, &size);
  rc = MPI_Comm_rank(MPI_COMM_WORLD, &rank);
  tag = 100;
  if(rank == 0) {
    strcpy(message, "Hello, world");
    for (i=1; i<size; i++)
      rc = MPI_Send(message, 13, MPI_CHAR, i, tag, MPI_COMM_WORLD);
  }
  else
    rc = MPI_Recv(message, 13, MPI_CHAR, 0, tag, MPI_COMM_WORLD, &status);
  printf( "node %d : %.13s\n", rank,message);
  rc = MPI_Finalize();
  return 0;
}

Thanks.
Looking forward.
