    • lustre 2.1 with patch ORNL-22, machine with several NUMA nodes
    • 4647

      The binding policy implemented by the ORNL-22 patch does not take care of NUMA aspects. It means ptlrpcd thread partners can be in different NUMA nodes. When the io requests will be processed by ptlrpcd threads in their affinity domain it will be more performant to have ptlrpcd partners in the same NUMA domain.
