| Outline of Final Research Achievements |
In this research, we tried to accelerate gravitational wave search using GPGPU. Parallelization and speeding up were main tasks on radiometric calculation.
Calculations were also made using KAGRA test run data from March to April 2016. We confirmed the state of data and the probability of computation by applying radiometry, assuming that KAGRA data with only one unit is virtually shifted in time and it is two detectors. Also, gravity wave radiometry calculation was performed using the public data of the US LIGO experiment.
