Abstract:

Parameter Estimation (PE) is a time-consuming process; we need to find a new way to accelerate it in view of many-GW-detection era towards 3G. A Frequency-domain CBC PE on 15 parameters with Nested sampling with MCMC sub-chains and IMRPhenomPv2 waveform model has been accelerated with GPU by factor of ~100. The codes are all newly written in C++ and CUDA and produce the same output as LALInference for cbcBayesPostProc
