公共集群申请GPU-Linux大棚
公共集群申请GPU
文章目录 一、脚本文件模板 二、节点的参数 三、申请步骤 1、创建.sh脚本文件 2、提交作业 3、查看作业结果
本文以自己学院的新集群 申请GPU为例旧集群 新集群
一、脚本文件模板
以下是自己总结的脚本文件模板，关键代码已经给出了注释，可以直接使用。
#! /bin/bash
### 表 示 这 是 一 个bash脚 本#SBATCH --job-name="define_name"
### 设置该作业的作业名
#SBATCH --output=tGpu02_out.%j.out
#SBATCH --error=tGpu02_err.%j.err#SBATCH --nodes=1
### 指 定 该 作 业 需 要1个节点 数,目前学院集群gpu只有1个节点，设置过多节点会报错#SBATCH --ntasks-per-node=32
### 每个节点所运行的进程数为32,经过测试，大于32个进程数会报错#SBATCH --partition=gpu
#SBATCH --gres=gpu:1
###SBATCH --gpus=1
###2、3含义相同，都是指定gpu数量，选其中1个即可
###1、2这两条必须全部都有，先指定分区，再指定gpu数量，如果缺少一个会报错，单节点最大申请1个GPU#SBATCH --nodelist=gpu1
###指定用哪个nodelist，即GPU，但由于目前集群只有1个GPU，所以不指定也可以###时间、扣费 可省
###SBATCH --time=2:00:00
### 作 业 最 大 的 运 行 时 间 ， 超 过 时 间 后 作 业 资 源 会 被SLURM回 收
###SBATCH --comment project_name
### 指 定 从 哪 个 项 目 扣 费 。 如 果 没 有 这 条 参 数 ， 则 从 个 人 账 户 扣 费source ~/.bashrc
###这句话不能省，用来申请GPU，否则申请不到
###该命令非常非常的重要
###该命令非常非常的重要nvidia-smi
which nvidia-smi
nvidia-smi
### 程 序 的 执 行 命 令
###source activate pytorch01
###python python.py
二、节点的参数
输入sinfo，查看学院公共集群可用节点
[jessy@workstation testpy]$ sinfo
PARTITION AVAIL TIMELIMIT NODES STATE NODELIST
cpu* up infinite 1 mix cpu1
gpu up infinite 1 idle gpu1三、申请步骤
1、创建.sh脚本文件
[jessy@workstation ~]$ mkdir gpu_use
[jessy@workstation ~]$ cd gpu_use/
[jessy@workstation gpu_use]$ vi gpu.sh
在 gpu.sh文件中，将刚刚模板中的文件粘贴到sh中，
#! /bin/bash
### 表 示 这 是 一 个bash脚 本#SBATCH --job-name="gpu"
### 设置该作业的作业名
#SBATCH --output=gpu_out.%j.out
#SBATCH --error=gpu_err.%j.err#SBATCH --nodes=1
### 指 定 该 作 业 需 要1个节点 数,目前学院集群gpu只有1个节点，设置过多节点会报错#SBATCH --ntasks-per-node=32
### 每个节点所运行的进程数为32,经过测试，大于32个进程数会报错#SBATCH --partition=gpu
#SBATCH --gres=gpu:1
###SBATCH --gpus=1
###2、3含义相同，都是指定gpu数量，选其中1个即可
###1、2这两条必须全部都有，先指定分区，再指定gpu数量，如果缺少一个会报错，单节点最大申请1个GPU#SBATCH --nodelist=gpu1
###指定用哪个nodelist，即GPU，但由于目前集群只有1个GPU，所以不指定也可以###时间、扣费 可省
###SBATCH --time=2:00:00
### 作 业 最 大 的 运 行 时 间 ， 超 过 时 间 后 作 业 资 源 会 被SLURM回 收
###SBATCH --comment project_name
### 指 定 从 哪 个 项 目 扣 费 。 如 果 没 有 这 条 参 数 ， 则 从 个 人 账 户 扣 费source ~/.bashrc
###这句话不能省，用来申请GPU，否则申请不到
###该命令非常非常的重要
###该命令非常非常的重要nvidia-smi
which nvidia-smi
nvidia-smi
### 程 序 的 执 行 命 令
source activate pytorch01
python python.py因为即要激活环境，并且运行python文件
[jessy@workstation gpu_use]$ vi python.pyimport torchprint("hello world!")
print(torch.cuda.is_available())
print(torch.cuda.get_device_name(0))2、提交作业
看一下文件夹下面的文件，并且提交
[jessy@workstation gpu_use]$ ls
gpu.sh python.py
[jessy@workstation gpu_use]$ sbatch gpu.sh
Submitted batch job 567
[jessy@workstation gpu_use]$ squeueJOBID PARTITION NAME USER ST TIME NODES NODELIST(REASON)491 cpu bash y202663 R 2-18:46:16 1 cpu1567 gpu gpu jessy R 0:02 1 gpu1
[jessy@workstation gpu_use]$ 3、查看作业结果
[jessy@workstation gpu_use]$ ls
gpu_err.567.err gpu_out.567.out gpu.sh python.py
[jessy@workstation gpu_use]$ cat gpu_out.567.out
