Hello IB people,
I set up an AMD dual quad-core system recently and ran some IB level
tests. The "ibv_ud_pingpong" and "ibv_rc_pingpong" tests show pretty
different results for UD vs RC (latency is more than double!). I'm
wondering if someone could shed light on the issue? Is there something
that needs to be updated or changed? Has someone else noticed this
phenomena?
I suggest you to use the performance utilities to measure performance:
ib_send_bw and ib_send_lat - for RC & UD send
ib_write_bw and ib_write_lat - for RDMA
