[mvapich-discuss] [Fwd: Specify hca device per node in a given run]

[Jim Stoffel]

  Sorry if you receive this twice.   Sending again as a member this time.

Is there a way to specify the HCA device on a per node
basis for a single instance of a MPI application execution?   
DAPL_PROVIDER (mvapich2) or VIADEV_DEVICE(mvapich)
can be used to specify the device which applies to all nodes in the
run.    Can the device be set for each individual node in a paramfile
or a hostlist file?

I would somehow like to have data transfer  through  hca0 of node0
and  hca1 of node1.

node0 DAPL_PROVIDER OpenIB-cma
node1 DAPL_PROVIDER OpenIB-cma-1

Please advise.
Thanks,
Jim
