[gmx-users] Scaling in parallel

I will be using Gromacs in parallel and I wanted to get a feel from
the users what has been their experience with scaling over a large
number of processors. Looking at the benchmark results, it seems that
the performance starts to level out around 30 processors. Has anyone
been able to run Gromacs over hundreds (200-300) of processors?

A question specific to the developers: is there a target date for the
next release of Gromacs? I had posted a note earlier regarding the
64-bit performance, and Erik indicated that the he has worked the
details into the next release. I plan to run Gromacs in a large G5

Thanks all,
