Large-scale CFD Applications and a Full GPU Implementation of a Weather Prediction Code on the TSUBAME Supercomputer
Speakers:

Abstract:
Many CFD applications have been successfully accelerated on GPUs, but for large-scale simulations that require memory beyond a single GPU, communication is required between GPUs over cluster nodes through PCI-Express and interconnects. To overcome performance bottlenecks and preserve parallel scalability, an overlapping technique between computation and communication is essential. This work presents results of an LBM for incompressible flow, and a Tsunami simulation solving the shallow water equation for simulations on the NVIDIA Tesla-based TSUBAME supercomputer of Tokyo Tech. In addition results will be presented on a complete GPU implementation of a production-level weather prediction code developed by the JMA that achieves 15 TFLOPS for an 80-fold speedup.
