介绍了基于数据分析框架RooFit和开放计算机语言OpenCL，将图形处理单元GPU的并行运算技术应用于Dalitz图分析的实现方法。基于该方法开发出的Dalitz图并行计算分析软件与使用中央处理单元CPU的Dalitz图分析软件相比，拟合速度提高了100倍以上，成为研究北京谱仪BESIII获取的大统计量实验数据的一个分析工具。

The implementation of applying the parallel computing techniques of Graphics Processing Units ( GPU) to the Dalitz plot analysis is introduced , which based on the data analysis framework RooFit and Open Computer LanguageOpenCL .The parallel computing software ofDalitz plot analysis which developed from this implementation speeds up the fitting more than 100 times comparing to the Dalitz plot analysis software using the Central Processing Unit ( CPU) , and becomes one of the analysis tools to study the large statistics experimental data accumulated by Beijing Spectrometer (BESIII).
