Subject: [hwloc-users] Process and thread binding
From: Gabriele Fatigati (g.fatigati_at_[hidden])

Dear hwloc users,

I'm binding process in a NUMA node and also associated OpenMP threads. I've
noted that, if I bind execution of all on different cores in the same NUMA
node , it works well.

If I bind process in NUMA node 0 for example, and thread on NUMA node 1, the
process is bound on NUMA node 1, and not 0.

Why this? Thread binding influence bind of main process?

Thanks in advance.
