Webinar: Scaling Soft Matter Physics to a Thousand GPUs and Beyond

September 22nd, 2012

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. On October 3, Dr. Alan Gray from the University of Edinburgh presents a webinar on his team’s experiences in scaling the application on the Cray XK6 hybrid supercomputer. The 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
