Hi, 
I am about to run nsdperf for testing the IB fabric in a new system 
comprising ESS (BE) and Intel-based nodes. 
nsdperf crashes reliably when invoking ESS nodes and x86-64 nodes in one 
test using RDMA: 

client          server          RDMA 
x86-64          ppc-64          on              crash
ppc-64          x86-64          on              crash
x86-64          ppc-64          off             success
x86-64          x86-64          on              success
ppc-64          ppc-64          on              success

That implies that the nsdperf RDMA test might struggle with BE vs LE. 
However, I learned from a talk given at a GPFS workshop in Germany in 2015 
that RDMA works between Power-BE and Intel boxes. Has anyone made similar 
or contrary experiences? Is it an nsdperf issue or more general (I have 
not yet attempted any GPFS mount)?
