Multiple right-hand-side setup for the DD-\alpha AMG

Richtmann, Daniel, Heybrock, Simon, Wettig, Tilo

Understand

The setup cost of a modern solver such as DD-\alpha AMG (Wuppertal Multigrid) is a significant contribution to the total time spent on solving the Dirac equation, and in HMC it can even be dominant.

We present an improved implementation of this algorithm with modified computation order in the setup procedure.
By processing multiple right-hand sides simultaneously we can alleviate many of the performance issues of the default single right-hand-side setup.
The main improvements are as follows: By combining multiple right-hand sides the message size for off-chip communication is larger, which leads to better utilization of the network bandwidth.
