In order to satisfy the research needs of Nanshan 25 m radio telescope of Xinjiang Astronomical Observatory(XAO)and study the key technology of the planned QiTai radio Telescope(QTT),the receiver group of XAO studied the GPU(Graphics Processing Unit)based real-time FRB searching algorithm which developed from the original FRB searching algorithm based on CPU(Central Processing Unit),and built the FRB real-time searching system. The comparison of the GPU system and the CPU system shows that: on the basis of ensuring the accuracy of the search,the speed of the GPU accelerated algorithm is improved by 35–45 times compared with the CPU algorithm.
