I have an "extreme" case below, for the sake of example.
Suppose one is running a MPI job with N >= 2 ranks, and at a certain moment the
code does the following:
.
.
.
If (rank == 0) {
MPI_Bcast(...);
}
.
.
.
std::cout << "Here A, rank = " << rank << std::endl;
MPI_Barrier(...);
std::cout <<
th matching but
different signatures.

In the case of the application I am working on, all ranks call MPI with the
same signature / types of variables.
I do not
compilers
- MPICH (or a derivative such as Intel MPI)
- PETSc 3.16.5
=> a success would strongly point to Open MPI

There is no simple way to get more information about this issue. If you have a
version of OMPI compiled in debug mode, you can increase the verbosity of the
collective framework to see if you get more interesting inf
Hello all,
The very simple code below returns mpiRC = 15.
const std::array< double, 2 > rangeMin { minX, minY };
std::array< double, 2 > rangeTempRecv { 0.0, 0.0 };
int mpiRC = MPI_Allreduce( rangeMin.data(), rangeTempRecv.data(),
rangeMin.size(), MPI_DOUBLE, MPI_MIN, PETSC_COMM_WORLD );
