With the ever-growing number of computing architectures, performance portability is an important aspect of (Lattice QCD) software. The Grid library provides a good framework for writing such code, as it thoroughly separates hardware-specific code from algorithmic functionality and already supports many modern architectures. We describe the implementation of a multigrid solver for Wilson clover fermions in Grid by the RQCD group. We present the features included in our implementation, discuss initial optimization efforts, and compare the performance with another multigrid implementation.
