Hi,
Sorry for late answer.
I've checked your source code, and I didn't find anything wrong,
everything works just fine with Open MPI trunk version. Could you tell
me which version did you use, so that I can debug with your generated
mpi libs?
By the way, I noticed that you put MPI_Init, MPI_Comm_rank,
MPI_Comm_size, and MPI_Finalize in the function that will be triggered
by the button press. This is only fine with the first button click, but
not for the second click and so on. It's better to place them in the
class initialization and finalization, so that they will only be
executed once.
Regards,
Shiqing

Hi,
I personally haven't try to program MPI with MFC, but in principle
it should work. What kind of error did you get, was there any error
message? Thanks.

Hi,
I have a MFC project, and need to add mpi functions in it, and
choose openmpi.
but I searched all of mail list , not. find the answer.
And I try to call mpi functions under MFC, as follows,
int ompi_test(int *argc, char **argv)
{
int rank, size;
MPI_Init(argc, &argv);
MPI_Comm_rank(MPI_COMM_WORLD, &rank);
MPI_Comm_size(MPI_COMM_WORLD, &size);
printf("Hello, world, I am %d of %d\n", rank, size);
MPI_Barrier(MPI_COMM_WORLD);
MPI_Finalize();
return 0;
}
void CSchedulerDlg::OnBnClickedButton1()
{
ompi_test(NULL, NULL);
}
but break at MPI_Init(argc, &argv);.
So what should I do?
Can anybody help me?
Thanks in advance.
Best Regards.
