问题描述

以vasp为例，假定你有很多结构，在init_clusters里面：

init_clusters/N-12-sg-4.vasp  init_clusters/N-15-sg-3.vasp  init_clusters/N-18-sg-2.vasp

现在想要用相同的INCAR，POTCAR，KPOINTS提交任务（当然，这些也可以不一样，需要适当修改下面程序），计算完的任务全部放在fp文件夹（提前手动建立）里面。

实际上需要满足：

  • 容错 custodian 可以自动解决vasp常见错误
  • 重启 计算过的任务不会重新计算
  • 远程提交 在本地可以提交的远程机器 （比如通过cl10向cl9提交任务）
  • 队列系统 需要适用于常见的队列系统

运行脚本

runvasp.py

机器配置文件

machine.json
可以参考dpgen-machine
这里可以配置任意数量的机器，下面一般本地slurm提交为例

运行原理

通过python paromiko软件打包本地文件到本地计算文件夹、或者远程机器计算文件夹，定时查看远程机器的计算状态，等任务计算完成之后，收回文件backward_files 列表

运行方式

nohup python -u runvasp.py &

运行结果

jr.json记录提交信息，用于重启，放置已经提交或者已经算完的任务再次被提交
