Psutil not detecting correct child processes

CPU resource utilization metrics for MPI jobs on SLURM systems appear to be inaccurate, suspect since psutil is not identifying the correct child processes of the main job:

 executor _processes dict_values([<Popen: returncode: None args: ['mpiexec', '-n', '20', 'fds', 'office_atria_...>])
child psutil.Process(pid=2546114, name='srun', status='sleeping', started='14:29:20')
child psutil.Process(pid=2546115, name='srun', status='sleeping', started='14:29:20')
child psutil.Process(pid=2546115, name='srun', status='sleeping', started='14:29:20')

Would expect to see a series of FDS child processes for each of the 20 cores it is running across, instead just see srun...

首先在 SLURM 上复现 MPI 作业，并检查 psutil 如何识别主作业的子进程。当进程列表包含全部 20 个核心所对应的预期 FDS 子进程，且 CPU 资源指标准确时，即表示完成。
