Binary Pulsar System Acceleration Search Method and Software Improvement

  • Millisecond pulsars are of great significance to gravitational wave detection and space navigation. We point out that the binary star system is closely related to the millisecond pulsar by citing the ATNF database. We analyze the search capabilities of binary pulsar system in early scientific data center. Although the current version of the accelsearch is highly optimized on CPU, it still consumes computing power under the huge amount of FAST data. We summarize the impact of orbital motion in binary pulsar system firstly, and then introduce the search technology. We write programs to optimize the GPU version of the acceleration search in order to improve the search efficiency. Our benchmark shows that using different zmax parameters to process different.dat files has significantly improved the speed.
