GPU Enabled Thermo-Mechanical Modelling of Granular Materials With Non-Spherical Particle Shape
Jeudi 12 avril 2018 14:00
- Duree : 1 heure
Lieu : CTRM meeting room, ESRF - 71 avenue des Martyrs - Grenoble
Orateur : Josh BOWDEN (CSIRO Materials Science and Engineering, Brisbane, Australia)
The CSIRO Computational Modelling group has a broad code base of Fortran routines, parallelised using OpenMP that can model millions of colliding particles of varying shape using super-quadric descriptors. This talk will present the integration of a heat transfer code for within-particle heat conduction that makes use of GPUs for solving heat conduction equations within the super-quadric particles. The method was scaled to the memory availability of a server node, thus enabling simulations of much greater number of particles even than than what is available on multiple GPUs. The code is written in C++ using iso-C Fortran bindings for collision data transfer and makes use of multiple OpenCL queues for asynchronous transfer of data with computation. Performance figures are shown looking at effects of number of GPUs, queues per GPU and OpenMP threads used to concurrently run the queues. Profiling results will be shown.
