超算云(GPU服务器)环境配置
最近在用并行超算云GPU服务器(中国国家网格12区)搭建毕设的环境,这里记录一下。
首先,超算云服务器的登录可以采用网页版、也可以采用客户端(超算云地址:https://cloud.paratera.com/ )。需要注意的是,并行超算云只提供windows和mac的客户端,Linux用户可能只有使用网页版的界面了(或者用pappcloud直接远程练ssh用vim写:( 哈哈,pappcloud的用法可参见官网下载的《papp_cloud使用手册》)。
超算云上最常见的是用module进行包管理(文档:https://modules.readthedocs.io/en/latest/module.html)。我们可以用module avail
命令来查看现有的包:
[macong@paratera01 ~]$ module avail ------------------------- /usr/share/Modules/modulefiles -------------------------
dotmodule-gitmodule-info modulesnulluse.own-------------------------------- /etc/modulefiles --------------------------------
mpi/compat-openmpi16-x86_64 mpi/mpich-x86_64
mpi/mpich-3.0-x86_64mpi/openmpi-x86_64
mpi/mpich-3.2-x86_64----------------------------- /software/modulefiles ------------------------------
alphafold/2.0
anaconda/2.7
anaconda/3.7(default)
anaconda/3.7.4
bcftools/1.10.1
具体新建环境相关操作大家可以参见module的文档,此处不再赘述。大家需要注意的是,因为Pytorch和Tensorflow对应的CUDA版本有出入,我们建议Pytorch和Tensorflow分别装两个不同的环境。
然后根据下列不同的命令对Pytorch和Tensorflow进行装载。
1. Pytorch环境装载与测试 【超算云(GPU服务器)环境配置】Pytorch 1.9.0 环境装载:
[macong@paratera01 project]$ module load anaconda/3.7.4(tensflow)
[macong@paratera01 project]$ source activate torch
(torch) [macong@paratera01 project]$
可以查看此时的torch版本:
(torch) [macong@paratera01 ~]$ pip list |grep torch
torch1.9.0+cu111
torchvision0.10.0+cu111
接下来我们编写test_torch.py测试文件:
# test_torch.py
import torch
print(torch.cuda.is_available())
采用以下的sub_torch.sh脚本提交到GPU运算节点运行(注意,提交脚本里面一定要有装载环境操作(在计算节点装载),在用户节点里装载环境没用(用户节点只能用于安装依赖包))
#!/bin/bash
#SBATCH -N 1
#SBATCH -n 5
#SBATCH -p gpu
#SBATCH --gres=gpu:1
#SBATCH --no-requeue
module load anaconda/3.7.4
source activate torch
export PYTHONUNBUFFERED=1
python test_torch.py
提交命令为
sbatch sub_torch.sh
(注意,不是bash sub_torch.sh,bash不能提交到计算节点)
用squeue查看队列情况
[macong@paratera01 project]$ squeue
CLUSTER: priv
JOBID PARTITIONNAMEUSER STTIMENODES NODELIST(REASON)CLUSTER: swarm
JOBID PARTITIONNAMEUSER STTIMENODES NODELIST(REASON)
16601003gpu sub_tensmacongRINVALID1 g0002
一段时间后,查看同目录下的slurm-16601003.out输出文件,我们看到
True
说明Pytorch环境配置成功。
2. Tensorflow 2.5.1 环境装载与测试: Tensorflow 2.5.1 环境装载:
[macong@paratera01 project]$ module load anaconda/3.7.4
[macong@paratera01 project]$ export LD_LIBRARY_PATH=/home/macong/project/cuda/lib64:$LD_LIBRARY_PATH
[macong@paratera01 project]$ source activate tensflow
(tensflow) [macong@paratera01 project]$
加载完毕后,可以查看此时的tensorflow版本
(tensflow) [macong@paratera01 project]$ pip list |grep tensorflow
tensorflow-estimator2.4.0
tensorflow-gpu2.4.1
接下来我们编写以下test_tensorflow.py文件:
# test_tensorflow.py
import tensorflow as tf
print(tf.test.is_gpu_available())
采用以下的sub_tensorflow.sh脚本提交到GPU运算节点运行(同样地,提交脚本里面一定要有装载环境操作。另外注意,因为Tensorflow需要cudnn,这里要额外地增加cuda动态链接库的加载地址)
#!/bin/bash
#SBATCH -N 1
#SBATCH -n 5
#SBATCH -p gpu
#SBATCH --gres=gpu:1
#SBATCH --no-requeue
module load anaconda/3.7.4
export LD_LIBRARY_PATH=/home/macong/project/cuda/lib64:$LD_LIBRARY_PATH
source activate tensflow
export PYTHONUNBUFFERED=1
python test_tensorflow.py
提交命令为
sbatch sub_tensorflow.sh
输出显示
job 16601097 on cluster swarm
同样,我们可以用squeue查看队列情况
[macong@paratera01 project]$ squeue
CLUSTER: priv
JOBID PARTITIONNAMEUSER STTIMENODES NODELIST(REASON)CLUSTER: swarm
JOBID PARTITIONNAMEUSER STTIMENODES NODELIST(REASON)
16601097gpu sub_tensmacongRINVALID1 g0039
一段时间后,查看同目录下的slurm-16601097.out输出文件,我们看到一长串打印输出

True
当然,我们只需要关注最后一行的“True”,说明Tensorflow环境配置成功。
3. 常用命令: (1) squeue
squeue可用于查看当前的任务队列信息,如之前我们看到的:
[macong@paratera01 project]$ squeue
CLUSTER: priv
JOBID PARTITIONNAMEUSER STTIMENODES NODELIST(REASON)CLUSTER: swarm
JOBID PARTITIONNAMEUSER STTIMENODES NODELIST(REASON)
16601097gpu sub_tensmacongRINVALID1 g0039
(2) scancel
scancel+任务id可用于将正在运行的任务杀掉,如杀掉正在运行的16601167任务
scancel16601167
对应的slurm-16601167.out文件中会显示:
slurmstepd: error: *** JOB 16601167 ON g0011 CANCELLED AT 2021-11-28T10:10:00 ***
