Acceleration of infrasound and radioactive transfer simulation with multicore processors

Kushida, Noriyuki

Infrasound wave propagation simulation and radioactive transfer simulation were accelerated with GPGPU and multicore processors. These simulation codes supports CTBTO mission that detects nuclear test. Since these applications have been carried out on an isolated workstation, high-performance computing units, like GPGPU and multicore processors, are helpful for more accurate simulation. As a result, we achieve 18.3 speedup for infrasound that enables us to run more reliable method than the other simpler method one the same calculation speed, and we achieve the Northern Hemisphere radioactive transfer simulation that have been virtually impossible so far.
