Gauge-equivariant pooling layers for preconditioners in lattice QCD

no code implementations20 Apr 2023 Christoph Lehner, Tilo Wettig

We demonstrate that gauge-equivariant pooling and unpooling layers can perform as well as traditional restriction and prolongation layers in multigrid preconditioner models for lattice QCD.

Gauge-equivariant neural networks as preconditioners in lattice QCD

no code implementations10 Feb 2023 Christoph Lehner, Tilo Wettig

We demonstrate that a state-of-the art multi-grid preconditioner can be learned efficiently by gauge-equivariant neural networks.

Accelerating HPC codes on Intel(R) Omni-Path Architecture networks: From particle physics to Machine Learning

no code implementations13 Nov 2017 Peter Boyle, Michael Chuvelev, Guido Cossu, Christopher Kelly, Christoph Lehner, Lawrence Meadows

This displays how a factor of ten speedup in strongly scaled distributed machine learning could be achieved when synchronous stochastic gradient descent is massively parallelised with a fixed mini-batch size.
