[mpich-discuss] Hydra binding

[Jain, Rohit]

I have 2 questions on hydra binding:


1)      If I don't specify any -binding option, does hydra runs application without setting any core affinity or with default core binding?
mpiexec -f hosts -n 8 ./app


2)      What are supported platforms? Are various binding options (cpu, socket, cache, rr etc) supported on various architectures of Intel and AMD processors?
"On supported platforms, Hydra automatically configures available process-core binding capability (currently using PLPA or hwloc)."

Regards,
Rohit
