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)?
