Description

technical field [0001] The invention relates to the technical field of parallel computing, in particular to a parallel computing component, a method, and a corresponding parallel software development method and system. Background technique [0002] At present, parallelization of serial programs is a common research and development method for parallel application software of numerical simulation. It is divided into two steps: first, under the condition of small-scale calculation, design data structures and numerical algorithms for practical application problems, and develop serial programs ;Secondly, based on the high-performance computer architecture and parallel programming environment, the serial program is parallelized. On the one hand, the obtained parallel program can obtain the same simulation results as the serial program under small-scale computing conditions; The number of cores is used to expand the calculation scale. [0003] The advantage of parallelization of s...
