Hello,
a recent openmpi update on my Arch machine seems to have enabled --nooversubscribe, as described in the manpage. Since I
regularly test on my laptop with just 2 physical cores, I want to set --oversubscribe by default.
How can I do that?
I am also a bit surprised, that openmpi takes the physical number of cores into account, not the logical (which is 4 on
my machine).
Thanks,
Florian
