ORCA 双杂化泛函计算 MP2 部分出错

indec

Sob 老师，最近在根据 大体系弱相互作用计算的解决之道 一文使用 ORCA 软件和 双杂化泛函 进行弱作用分析计算；输入文件如下：!RI-PWPB95 D3BJ RIJK def2-TZVP def2/JK def2-TZVP/C grid4 tightSCF
%maxcore 4000

%pal nprocs 32
end

*xyz 0 1

坐标已省略，100+ 原子，（C、N、S、O、H）
*

out 文件里，ORCA SCF 部分能够顺利收敛
               *                     SUCCESS                       *
               *           SCF CONVERGED AFTER  18 CYCLES          *

但是 MP2 部分就会持续报错

Primary job  terminated normally, but 1 process returned
a non-zero exit code.. Per user-direction, the job has been aborted.

--------------------------------------------------------------------------
mpirun detected that one or more processes exited with non-zero status, thus causing
the job to be terminated. The first process to do so was:

  Process name: [[56096,1],5]
  Exit code:    12

核数给少点，内存给大点
