Abstract: A method and system for filtering a parallel computing result. The method comprises: simultaneously generating an input value of a first valid position (FVP) of each fragment, simultaneously calculating the input value of the FVP respectively corresponding to each fragment to obtain an output result corresponding to the input value of each FVP, sequentially selecting the approach of the output result of second to S-th fragments according to the output result of the FVP of each fragment, and filtering the parallel computing result to finally obtain the correct parallel computing result.
