查看“QE工作命令”的源代码

QE的工作环境:
  使用intel mpi
  Ultrasoft PP 与 PAW 近亲
  cif2cell -h
  cif2cell Si.cif   ! 查看结构信息
  cif2cell Si.cif -p quantum-espresso
  xcrysden															     ！输入输出文件

==== 结构优化OPT ====
  nohup mpirun -np 36 pw.x < vc-relax.in > vc-relax.out &              ！运行QE
  grep ! vc-relax.out                                                  ！跟踪运行过程
  grep "Total force" vc-relax.out                                      ！跟踪运行过程
  "Begin final coordinates" "Total energy"                             ! 之间为结构优化结果
  grep P= vc-relax.out
