In the event reconstruction, we need to exact the photon electron(PE) hit time and PE charge from waveforms. We developed a new method called Fast Scholastic Matching Pursuit(FSMP). It is based on a Bayesian principles, and the possible solutions are sampled with Markov Chain Monte Carlo(MCMC). To accelerate the method, we ported it to GPU, and could analysis the waveforms with 0.01s per waveform. This method will benefit event reconstruction. The position and energy resolution will be improved, as the method extracts all the information in the waveforms.
