Hello, I have installed openmpi from the ubuntu repository for the 64-bit dual core AMD processor.
and i tried to compile the simple test program with the help of the tutorial page but nothing seems to happen. #include <stdio.h> #include <mpi.h> int main(int argc,char *argv[]) { int rank; MPI_Init(&argc,&argv); MPI_Comm_rank(MPI_COMM_WORLD, &rank); printf("my rank=%d\n",rank); MPI_Finalize(); return 0; } then from the console i issued the following command mpicc test.c -o test mpirun -np 4 test nothing happens. actually after the command "mpicc test.c -o test" shouldnt i be having a .o file? I do not understand how do i get to know if my current installation is fine or not. Any suggestion? Regards Sajjad
