Hi.
I'm testing Open MPI 4.0.0 and I'm struggling with a weird behaviour. In a very
simple example (very frustrating). I'm having the following error returned by
MPI_Send:
[gafront4:25692] *** An error occurred in MPI_Send
[gafront4:25692] *** reported by process [3152019457,0]
[gafront4:25692] *** on communicator MPI_COMM_WORLD
[gafront4:25692] *** MPI_ERR_OTHER: known error not in list
[gafront4:25692] *** MPI_ERRORS_ARE_FATAL (processes in this
communicator will now abort,
[gafront4:25692] *** and potentially your MPI job)
In the same machine I have other two instalations of Open MPI (2.0.2 and 2.1.2)
and they all run successfully this dummy program:
#include <stdio.h>
#include <mpi.h>
int main(int argc, char **argv) {
int process;
int population;
MPI_Init(NULL, NULL);
MPI_Comm_rank(MPI_COMM_WORLD, &process);
MPI_Comm_size(MPI_COMM_WORLD, &population);
printf("Hello World from proccess %d out of %d\n", process, population);
int send_number = 10;
int recv_number;
if (process == 0) {
MPI_Send(&send_number, 1, MPI_INT, 1, 0, MPI_COMM_WORLD);
printf("This is process 0 reporting::\n");
} else if (process == 1) {
MPI_Recv(&recv_number, 1, MPI_INT, 0, 0, MPI_COMM_WORLD,
MPI_STATUS_IGNORE);
printf("Process 1 received number %d from process 0\n",
recv_number);
}
MPI_Finalize();
return 0;
}
I'm really upset about recurring to you with this problem. I've been arround it
for days now and can't find any good solution. Can you please take a look? I've
enabled FI_LOG_LEVEL=Debug to see if I can trap any information that could be
of use but unfortunetly with no success. I've also googled a lot, but I don't
see where this error message might be pointing at. Specially having two other
working versions on the same machine. The thing is that I see no reason why
this code shouldn't run.
The following is the configure command line, as given by ompi_info.
Configure command line: '--build=x86_64-linux-gnu' '--prefix=/usr'
'--includedir=${prefix}/include'

Thank you for your time.
