Hi Bruno

-h or --help works all the time ;-)

Regarding changing cpus. Yes, they change. However, -j2 should give 200%
(with "top") and not 250%.

Regarding your variants:
yade-batch -j1 --job-threads=2 file.table file.py: should still use one core, but I never used it
yade-batch -j2 --job-threads=2 file.table file.py: one simulation at a time with 2 cores
yade-batch -j4 --job-threads=2 file.table file.py: two simulations at a time with 2 cores each
yade-batch -j16 --job-threads=1 file.table file.py: 16 simulations at a time with 1 core each

Cheers
Klaus
