mpirun -gdb -n 2 -f hostile ./example.exe
When I do so, it just executes, without waiting for me to set a breakpoint, or execute the gdb "run" command.
I am using the 2021 compiler and I know there is a later version. But I did make sure that mpif90, which I used to compile, and mpirun, which I used to run, are consistent.
Is this a question that folks on the Intel community could address. Or is it an MPICH question? Any thoughts on what may causing the issue, of immediate executio without waiting for a "run" command?

I think this is better asked in Intel® oneAPI HPC Toolkit - Intel Community which deals with MPI issues. I don't see a connection to the Intel compiler. But are you using any Intel tools? If you're using MPICH you're not using Intel MPI, and I was under the impression that "mpif90" invoked gfortran by default - that "mpifort" was used to use the Intel compiler. I may be mistaken here.

I will go to that community you suggested. But can you tell me, what is the easiest way to identify if I am using MPI or MPICH? Do you know?
