enable collective offload support for inifiniband

Solution Unverified - Updated -

Environment

  • Red Hat Enterprise Linux 6

Issue

  • Is collective offload, aka core-direct, functionality is available in RHEL 6.
  • Need the ability to run the iboffload code on the cluster nodes.
  • The functionality may only be available in an OFED release and it is not upstream so perhaps it is not on Red Hat's radar.
  • Do libibverbs, libmlx4 and the RHEL 6 kernel have collective offload/core-direct support and if not are there plans for its implementation?
  • If there are no current plans for the implementation of collective offload/core-direct support what can one do to get the ball rolling on its implementation?
