Abstract

In order to drastically shorten the runtime of a weather prediction code ASUCA developed by the JMA (Japan Meteorological Agency) for the purpose of the next-generation weather forecasting service, the entire parts of the huge code are re-written for GPU computing from scratch. By introducing many optimization techniques and several new algorithms, very high performance of 145 TFlops has been achieved with 3990 GPUs on the TSUBAME 2.0 supercomputer. It is quite meaningful to show that the GPU supercomputing is really available for one of the major applications in the HPC field.
