Hello! I created https://openib.org/svn/trunk/contrib/mellanox/perftest
This directory includes gen2 uverbs microbenchmarks - useful as usage examples and for performance tuning. Testing methodology: - CPU clock instruction is used to get CPU clock without context switch. - Median (as opposed to average) result is reported. The median is less sensitive to extreme scores. An option to report the full result distribution for alternative statistical analysis is provided. Architectures supported: - i686, x86_64 Tests in this directory: there is currently one test: rdma_lat.c - latency test with RDMA write transactions Code is originally based on the pingping test. I intentionally did not rename functions from pingpong_ to rdma_ to make it easier to share some code with libibverbs/examples later. Current results: I currently observe latency below 3.5 usec. Drop me a note if you find this useful. Thanks, -- MST - Michael S.
