Job Submission

One the files installations have been done and the profiles defined by creating symbolic links to the images in the top-level directory, it is time to submit a test job. Write a test program like:

#include <stdio.h>
#include "mpi.h"

int main(int argc, char* argv[])
{
    int rank, namelen;
    char processor_name[MPI_MAX_PROCESSOR_NAME];

    MPI_Init(&argc, &argv);

    MPI_Comm_rank(MPI_COMM_WORLD, &rank);
    MPI_Get_processor_name(processor_name, &namelen);
    printf("Process %d on %s\n", rank, processor_name);
#if 0
    for (;;)
        ;
#endif
    MPI_Finalize();
    return 0;
}

Compiling

The program can be compiled on the login node using:

$ gcc -o hello_world hello_world.c

Submitting Job

The job needs to be submitted using the cobalt resource manager. For the hello_world program use the following command:

cqsub -p ZeptoOS -n <number-of-processes> -t <time> -k <profile-name> ./hello_world
