Ok, here is the code I'm working with....mkdir keeps giving me a -1
failure...can anyone spot what I"m doing wrong?
#include <stdio.h> /* all IO stuff lives here */
#include <stdlib.h> /* exit lives here */
#include <string.h> /* strcpy lives here */
#include <mpi.h> /* MPI and MPI-IO live here */
#include <sys/stat.h>
#define MASTER_RANK 0
#define TRUE 1
#define FALSE 0
#define BOOLEAN int
int main( argc, argv )
int argc;
char* argv [];
{
int my_rank, i,pool_size;
BOOLEAN i_am_the_master = FALSE;
MPI_Init(&argc, &argv);
MPI_Comm_rank(MPI_COMM_WORLD, &my_rank);
MPI_Comm_size(MPI_COMM_WORLD, &pool_size);
if (my_rank == MASTER_RANK)
i_am_the_master = TRUE;
// MASTER CODE
if (i_am_the_master)
{
}
// SLAVE CODE (THIS IS WHERE THE MAGIC HAPPENS
if (!i_am_the_master)
{
char fullpath[10000];
sprintf(fullpath,"/tmp/oooo/RANK%d", my_rank);
printf("MY PATH TO CREATE %s", fullpath);
int mkdir_return;
mkdir_return = mkdir(fullpath,0777);
printf("mkdir results: %d\n", mkdir_return);
}
MPI_Finalize();
exit(0);
}
