First Steps of YALES2 Code Towards GPU Acceleration on Standard and Prototype Cluster
Abstract:
Learn how we explore the feasibility of porting YALES2 on GPU. YALES2 is an HPC application for turbulent combustion modeling from primary atomization to pollutant prediction on massive complex meshes. It runs over thousands of CPU cores solving several billions element meshes through MPI+OpenMP programming. The work presented here is focusing on a preliminary feasibility study of GPU porting. In this session we will describe: a methodology for porting a large code to GPU; the choices that have been made regarding the different constraints; the performance results. We will also present the final benchmarks run across several platforms form classic Intel+Kepler cluster at ROMEO HPC Center (University of Reims, France) to prototypes with IBM Power8+Pascal at IDRIS (CNRS, France).
