SMPI replay fails --- corner case
Hello, I went into a bug whith SMPI replay.
It seems that if every rank starts by a broadcast, the simulation fails. I don't know yet if it is from batsim or simgrid.
I won't have time know to debug it, as it is not blocking for me. But I think that making an issue is important so we can trace the issue.
I made two examples, one that is working and another failing.
To run the mwe, untar batsim_tit_mwe.tar and go into the folder:
# Run the working workload
nix-shell --pure --command "robin robin_ok.yaml"
# Run the buggy workload
nix-shell --pure --command "robin robin_bug.yaml"
