【摘要】 用组态相互作用方法计算了二电子体系电子关联能。为了获得高精度的结果往往需要巨大的计算量 ,以往单个处理器上的串行计算通常存在着机时长 ,内存不够的严重困难 ,为此采用并行分块消去迭代法 ,同时在多个处理器上并行计算 ,得到了氦原子基态关联能更多还原

【Abstract】 The Modified Configuration Interaction method(MCI)is used to calculate the correlated energy of multi electron systems.For obtaining the higher precision,it calls for huge computings.In order to handle this problem,which will cost much CPU time and memory room if only using one CPU to do it, the parallel multisection recurrence algorithm is adopted by using several CPUs to get the ground state energy of Helium atom at the same time.
