Subject: [gpfsug-discuss] nsdperf crash testing RDMA between Power BE and Intel nodes
Sent by: [email protected]
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)?
Mit freundlichen Grüßen / Kind regards
