Description

We describe our experiences porting the Regensburg implementation of
the DD-αAMG solver from QPACE 2 to QPACE 3. We first review porting from
the first generation Intel Xeon Phi processor (Knights Corner) to its
successor (Knights Landing). Secondly, we present an overview of
Omni-Path, comparing it to the well-known competitor InfiniBand.
Finally, we present the performance of the code on a single processor as
well as the scaling on many nodes.
