[gpaw-users] GPAW and InfiniBand

[Morten Bjørn Bakkedal]

I'm using GPAW on DTU's central Xeon based HPC cluster which is interconnected
with InfiniBand. I'm currently doing computations on pretty large systems with
64 atoms and 576 bands on 64 computer cores.

Now I thinking about how to be sure that the processes are communicating using
the fast InfiniBand connection. Do I need to add any compiler flags to the
customize.py to compile GPAW to use the fast connection? As I wrote a few days
ago, I'm using the ACML library.
