Question

我有以下提交脚本名为“test.sub”：

#!/bin/bash
#SBATCH --workdir=./
#SBATCH -o test.out
#SBATCH --partition=debug
#SBATCH --nodes=1
#SBATCH --ntasks=1
#SBATCH --requeue
#SBATCH --job-name=test

x=0

while [ $x -le 100 ]; do
   echo "Test $x" >> test.out
   sleep 100
   x=$(($x+1))
done

当我提交此作业脚本时，作业确实开始了。但是，当我使用scontrol show job检查作业的状态时，收到以下消息：

...
JobState=RUNNING Reason=None Dependency=(null)
Requeue=1 Restarts=0 BatchFlag=1 Reboot=0 ExitCode=0:0
...
NumNodes=1 NumCPUs=64 CPUs/Task=1 ReqB:S:C:T=0:0:*:*
TRES=cpu=64,node=1

这是否意味着作业使用64 cpus而不是作业脚本中指定的1？如果是这样，我该怎么做才能解决这个问题？我有以下SLRUM配置文件（/etc/slurm-llnl/slurm.conf）：

感谢您帮助我！：）

问题在于

行

SelectType=select/linear

在配置文件中。它指示Slurm将节点分配给作业。如果您希望Slurm分配核心，则需要

SelectType=select/cons_res
SelectTypeParameters=CR_Core_Memory

有关SelectTypeParameters

的替代选项，请参阅this documentation
