Hi,
I'm starting to use OpenMPI and I'm having some troubles. I wrote a
simple program that tries to open files using the function
MPI_File_open(). Like below:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <mpi.h>
int processoPrincipal(void);
int processosEscravos(void);
int main(int argc, char** argv) {
int meuRank, numeroProcessos;
MPI_File arquivoEntrada, arquivoSaida;
MPI_Init(&argc, &argv);
MPI_Comm_rank(MPI_COMM_WORLD, &meuRank);
MPI_Comm_size(MPI_COMM_WORLD,&numeroProcessos);
MPI_File_open(MPI_COMM_WORLD, argv[1], MPI_MODE_RDONLY,
MPI_INFO_NULL, &arquivoEntrada);
strcat(argv[1], ".bz2");
MPI_File_open(MPI_COMM_WORLD, argv[1], MPI_MODE_RDWR |
MPI_MODE_CREATE, MPI_INFO_NULL, &arquivoSaida);
if (meuRank != 0) {
processoPrincipal();
} else {
processosEscravos();
}
MPI_Finalize();
return 0;
}
But I'm getting a error message like:
*** An error occurred in MPI_Barrier
*** An error occurred in MPI_Barrier
*** after MPI was finalized
*** MPI_ERRORS_ARE_FATAL (goodbye)
*** after MPI was finalized
*** MPI_ERRORS_ARE_FATAL (goodbye)
What is this ?
