Hello, I am new to MPI and also this list. I wrote an MPI code with several MPI_Bcast calls in a loop. My code was getting stuck at random points, ie it was not systematic. After a few hours of debugging and googling, I found that the issue may be with the several MPI_Bcast calls in a loop.
I stumbled on this test code which can reproduce the issue: https://github.com/fintler/ompi/blob/master/orte/test/mpi/bcast_loop.c Im using OpenMPI v1.8.4 installed from official Arch Linux repo. Is it a known issue with OpenMPI? Is it some problem with the way openmpi is configured in my system? Thanks in advance. Sachin
