[gmx-users] How to compile/run Gromacs on native Infiniband?

[Bert]

Dear all,

My cluster has a FDR (56 Gb/s) Infiniband network. It is well known that
there is a big difference between using IPoIB (IP over IB) with a normal
sockets application and using native InfiniBand with an application that
has been coded directly to the native IB verbs interface. The latter one
gets much higher throughput and lower latency, while spending less CPU on
networking.

Therefore, I wonder if Gromacs has the native IB verbs interface. If so,
how to compile and run Gromacs on native Infiniband? Any suggestions will
be appreciated.

Best Regards,
Bert
