If you bind process X to coreA and then thread Y of process X to coreB, what you should now see with get_cpubind is that process X is now bound to cores A+B, thread Y to B, and all other threads to A.Hi Birce,
I'm so confused..
I'm binding MPI processes with set_cpu_bind and it works well. The problem is when I try to bind process and threads.
It seem that thread process influence bind of main thread.
And from hwloc manual:
Bind current process or thread on cpus given in bitmap set.
Why you are saying tha process bind is not possible? I'm using it and it work well!
