Description

We describe our experiences porting the Regensburg implementation of the
DD-$\alpha$AMG solver from the first-generation Intel Xeon Phi processor
(Knights Corner) to its successor (Knights Landing). We present the
performance of the code on a single processor as well as the scaling
behavior on many nodes of QPACE 3, which utilizes Intel's new Omni-Path
fabric.
