Hello, I just got some new cluster hardware :) :(
I can't seem to overcome an openib problem
I get this at run time
error polling HP CQ with -2 errno says Success
I've tried 2 different IB switches and multiple sets of nodes all on one
switch or the other to try to eliminate the hardware. (IPoIB pings
work and IB switches ree
I've tried both v1.3.3 and v1.2.9 and get the same errors. I'm not
really sure what these errors mean or how to get rid of them.
My MPI application work if all the CPUs are on the same node (self btl
only probably)
Any advice would be appreciated. Thanks.
