EM to PP facility communication speedup for a single-node

Details

    • New Feature
    • Status: Closed (View Workflow)
    • Major
    • Resolution: Fixed

    • ExeMgr, PrimProc
    • None

    Description

      After MCOL-5001 there is a possibility to use in-memory exchange b/w EM and PP bypassing local network hop thus reducing time spent in kernel moving data from EM to PP.
      The suggested approach is to replace network communication with a queue in DEC class that can be used to send primitive messages(sometimes with data, e.g. for JOINs) from EM to PP.
