Research Abstract

The global gravitational wave observation network is expected to start around year 2017 or 2018. Gravitational wave radiometry is a method which will make possible to extract gravitational signal from certain direction of the sky using multi-detectors and long duration integration, even if waves are incoherent and weak. However, the radiometry calculation requires verbose calculations such as iteration for sky positions and of short chunks for long observation. Thus, the aim of our research program is high-speed up of radiometry calculation using GPGPU (General-purpose computing on graphics processing units).
We achieved about 100 times faster calculation with GPGPU comparing with previous CPU. It is not straightforward to compare GPU and CPU in equal condition, but the result is derived on same cost-performance. Using this speed-up, we studied the variation of application of radiometry, e.g. source separate filter using different waveband.
