本地通过apt安装Slurm后无法找到sbatch.c文件的技术问询

Hey there! Let's break down why you can't locate the sbatch.c file after installing Slurm via sudo apt-get install -y slurm-wlm slurm-wlm-doc, and how to fix it:

为什么找不到sbatch.c？ #

The slurm-wlm and slurm-wlm-doc packages you installed are precompiled binary packages—they only include ready-to-run executables (like the sbatch command), configuration files, and documentation. Source code files like sbatch.c aren't included in these packages by default.

获取sbatch.c的两种方法 #

方法1：通过APT获取对应版本的源码包 #

APT has a built-in way to download the source code for packages you've installed. Here's how:

• First, install tools needed to handle source packages:

  sudo apt-get install -y dpkg-dev
  

• Next, ensure your system can access source repositories. Open /etc/apt/sources.list with a text editor (like nano) and check for lines starting with deb-src (matching your Ubuntu version's main repository). If missing, add a line like this (replace jammy with your Ubuntu codename, e.g., focal for 20.04):

  deb-src http://archive.ubuntu.com/ubuntu/ jammy main universe
  

• Update your package lists:

  sudo apt update
  

• Download the Slurm source code:

  apt source slurm-wlm
  

  This will create a directory in your current folder with the Slurm source code. You'll find sbatch.c inside slurm-<version>/src/sbatch/.

方法2：从Slurm的Git仓库克隆源码 #

If you want the latest (or a specific) version of the source code, clone the official repository:

• Clone the repo:

  git clone https://github.com/SchedMD/slurm.git
  

• Switch to the branch/tag matching your installed Slurm version (check with sbatch --version):

  cd slurm
  git checkout <version-tag>  # e.g., git checkout slurm-23.02.6
  

• Navigate to the sbatch source directory:

  cd src/sbatch/
  

  You'll find sbatch.c here.

额外提示：如果只是测试sbatch命令 #

If you don't actually need the source code and just want to test using the sbatch command, you don't need sbatch.c at all. Create a simple test script (e.g., test_job.sh):

#!/bin/bash
#SBATCH --job-name=test_job
#SBATCH --output=test_output.txt

echo "Hello from Slurm!"
date

Then submit it with:

sbatch test_job.sh

You'll get a job ID, and the output will be in test_output.txt once the job runs.
