Question

hpc的每个单个节点的最大可能核心数等于24，但它们通常都不可用，所以我想在4个节点上运行代码，每个节点有20个核心（而不是24个）。

使用MPI是否正确？

#!/bin/sh
#
# Replace <ACCOUNT> with your account name before submitting.
#
#SBATCH --account=aaa            # The account name for the job.
#SBATCH --job-name=job_name      # The job name.
#SBATCH -N 4                     # The number of nodes to use
                                 # (note there are 24 cores per node)
#SBATCH --exclusive
#SBATCH --time=23:58:00          # The time the job will take to run.

source activate env_python
mpirun -n 80 python script.py

# End of script

这可以做你想要的：

-n 80

请求4个节点，每个节点有20个任务，这些节点将映射到80个MPI等级。那时console.error node_modules\vue\dist\vue.runtime.common.js:589 [Vue warn]: Cannot find element: #app console.error node_modules\vue\dist\vue.runtime.common.js:589 [Vue warn]: You are using the runtime-only build of Vue where the template compiler is not available. Either pre-compile the templates into render functions, or use the compiler-included build. (found in <Root>)不是必需的。

正确运行具有更多节点和更少内核的Slurm脚本
