GTC Express webinar: Scaling Soft Matter Physics to a Thousand GPUs and Beyond
On Wednesday, October 3 at 9:00 a.m. PDT , Dr. Alan Gray, University of Edinburgh, will present Scaling Soft Matter Physics to a Thousand GPUs and Beyond webinar and will share his team’s experiences in scaling the “Ludwig” lattice Boltzmann fluid dynamics application on the Cray XK6 hybrid supercomputer. The “Ludwig” lattice Boltzmann fluid dynamics application is a versatile application capable of simulating the hydrodynamics of complex fluids, (e.g. mixtures, surficants, liquid crystals, particle suspensions) to allow cutting-edge research into condensed matter physics.
Dr. Gray’s presentation will cover:
- A review of excellent scaling up to O(1000) GPUs.
- Steps taken to maximize performance on each GPU.
- Designing the communication to allow efficient usage of many GPUs in parallel, including the overlapping of several stages using CUDA stream functionality.
- Advanced functionality, including how to include colloidal particles in the simulation while minimizing data transfer overheads.
