P.S. For the future reference we also need to keep launch scripts that were
used to be able to carefully reproduce. Jeff mentioned that on the wiki
page IFRC.

Thank you, Arm!
Good to have vader results (I haven't tried it myself yet). Few
comments/questions:
1. I guess we also want to have 1-threaded performance for the "baseline"
reference.
2. Have you tried to run with openib, as I mentioned on the call I had some
problems with it and I'm curious if y
I added some result to https://github.com/open-mpi/2016-summer-perf-testing
The result shows much better performance from 2.0.0 and master over 1.10.3 for
vader. The test ran with Artem’s version of benchmark on OB1, single node, bind
to socket.
We should have a place to discuss/comment/collab

Sweet -- thanks
Jeff and others,
1. The benchmark was updated to support shared memory case.
2. The wiki was updated with the benchmark description:
https://github.com/open-mpi/ompi/wiki/Request-refactoring-test#benchmark-prototype
Let me know if we want to put this prototype to some general place. I think

Hi Nathan,
You gave me a hit, thanks!
I applied your patches and added "-mca btl_openib_flags 311" to the mpirun
option, then it worked for me.
[mishima@manage OMB-3.1.1-openmpi2.0.0]$ mpirun -np 2 -mca btl_openib_flags
311 -bind-to core -report-bindings osu_bw
