Institutue of Physics, Academia Sinica (AS) is leading gravitational wave researches in Taiwan. AS and 7 other universities and instuties joined the Asia-based KAGRA collaboration.

KAGRA is the first km-scale project to use cryogenic and underground technology. KAGRA is part of the International Gravitational-Wave Observatory (IGWN), in collaboration with LIGO and Virgo.

Contributions of ASGC at this stage include:

 1. GPU-accelerated parameter estimation by DiCOS

   – Evaluation of likelihood function by repetition over ~100,000 frequency bin

   – able to achieve ~100x speedup for some processes

 2. Data backup and delivery

 3. Monte Carlo Simulations
