چکیده انگلیسی
In order to satisfy the research need of Nanshan 25 m radio telescope of Xinjiang Astronomical Observatory (XAO) and study the key technology of the planned QiTai radio Telescope (QTT), on the basis of the original CPUÂ (Central Processing Unit)-based real-time search algorithm of FRBs (Fast Radio Bursts), we have studied the GPUÂ (Graphics Processing Unit)-based real-time search algorithm of FRBs, and built the corresponding real-time search system of FRBs. We have made the comparison and analysis on the GPU system and CPU system, the test result shows that under a given searching accuracy, the speed of the GPU-accelerated algorithm is improved by 35-45 times compared with that of the CPU algorithm.
