Research Abstract |
In 2006, NVIDIA presented CUDA as GPU computing environment for genericl computations, and after that many time-consuming applications are ported to GPU and achieved extreme speed-ups. For large-scale computation using supercomputers, efficient data transfer between GPUs is the most important. FFT is used in many scientific simulations and requires all-to-all communications between GPUs. We presented a novel scheduling techniques of PCI-Express data transfer between host and GPU, and InfiniBand data transfers between nodes. As a result, we could achieve scalable performance even if many other users' jobs are running on the shared network.
