Description

pxshm is currently only supported on the GNI and NetLRTS layers. It should be trivial to allow its use on MPI and Verbs (and OFI when it gets merged), to say nothing of its performance.

History

#1 Updated by Sam White 11 days ago

  • Parent task set to #1497

#2 Updated by Sam White 11 days ago

  • Subject changed from Enable use of pxshm on mpi and verbs builds to Enable use of pxshm/xpmem on mpi and verbs builds

Also, './build charm++ gni-crayxe xpmem' fails to build because it tries to build pxshm and xpmem both for some reason.
