快速的4π立体角粒子轨迹识别一直是粒子物理领域的难题，特别是在核乳化探测器的应用中。最近计算机技术的进步为它的实现开辟了道路。本文报道了一种基于GPU技术与多线程编程相结合的快速4π立体角粒子轨迹重建方法，并详细比较了cpu与GPU的处理时间。通过采用3个最先进的gpu多线程编程，实现了3D乳液探测器数据处理速度比单线程CPU处理快60倍，具有出色的跟踪性能，相当于每小时扫描15 cm2的乳液表面。
Fast 4π solid angle particle track recognition has been a challenge in particle physics for a long time, especially in using nuclear emulsion detectors. The recent advances in computing technology opened the way for its realization. A fast 4π solid angle particle track reconstruction based on GPU technology combined with a multithread programming is reported here with a detailed comparison of processing time by CPUs with respect to using GPUs. By employing 3 state-of-the-art GPUs with a multithread programming, a 60 times faster processing of 3D emulsion detector data has been achieved with an excellent tracking performance in comparison with a single-thread CPU processing, corresponding to processing of 15 cm2 emulsion surface scanned per hour.
