Subject: Re: [OMPI devel] Remove IMB 2.3 from ompi-tests?
From: Holger Mickler (holger.mickler_at_[hidden])

Hi Jeff, all,

would you mind sharing this patch? We'd like to test our current VT version with
some MPI RMA code :)

Does anyone know of some (small) code/benchmark that uses all available MPI RMA
functionality? As far as I see, IMB only uses fence and put/get/accumulate. No
locks or post/wait/start/complete...

Thanks!

Holger
