Thanks for the report! I can reproduce the error. However the infinite loop condition is not that simple :(.
I generated all possible 4-node MSG jobs with 0-filled communication matrices and 0|1-filled computation vectors thanks to python magic:
import itertools
s = sorted({x for x in itertools.product([0,1], repeat=4)})
for a,b,c,d in s:
print('- {{"name":"j{a}{b}{c}{d}", "cpu_json":"[{a},{b},{c},{d}]"}}'.format(a=a,b=b,c=c,d=d))
I then executed all combinations (thanks to this yaml file) with this command:
export BATSIM_DIR=/path/to/batsim/dir
${BATSIM_DIR}/tools/experiments/execute_instances.py issue23.yaml
Expected output:
[...]

2017-05-05 15:57:37,786 WARNING: Number of skipped instances: 8

https://github.com/simgrid/simgrid/issues/165 fixed thanks to @frs69wq.
I will close the bug once we will be able to use the up-to-date SimGrid version (when SMPI replay multiple on steroids will work).
Hello,
maybe you can cherry-pick https://github.com/simgrid/simgrid/commit/857e3b2171472a3d6db57944a99f8986aff18b0a ?
Hello and thanks! Cherry-picked simgrid/simgrid@857e3b2 in ba2856c1e.
Only the 0-filled case does not pass now, with a quite clean error. I think the error will not happen at all in up-to-date SimGrid.
We plan to go back to the main SG branch soon. I'll try to make a clean SG example of our dynamicity needs this week and I know @Shurakai plans to improve SMPI dynamicity soon.
