| Abstract | 针对脉冲星信号实时消色散处理需求，实现了基于GPU的非相干消色散算法。采用高性能并行计算方法对非相干消色散算法的多线程处理进行了深入研究，提出了算法的并行化加速方案，解决了消色散算法计算量大无法实时处理问题。分析算法的密集型计算部分，高效利用GPU的层次存储结构，提高了GPU资源利用率，进而减少了计算时间，显著提升了非相干消色散算法的计算性能。 |
| Other Abstract | In order to meet the requirements of real-time de-dispersion processing of pulsar signals, a GPU based incoherent de-dispersion algorithm is implemented. We use high-performance parallel computing methods to conduct in-depth research on the incoherent de-dispersion algorithm for multi-thread processing, and propose a parallel acceleration scheme for the algorithm, which solves the problem that the de-dispersion algorithm has a large amount of calculation and cannot be processed in real time. We analyze the intensive computing parts of the algorithm, efficiently use the hierarchical storage structure of the GPU, improve the utilization rate of GPU computing resources, thereby reducing the calculation time, and significantly improving the calculation performance of the incoherent de-dispersion algorithm. |
