由于超算的便捷性，目前开始使用超算，但本人对于Linux命令流一窍不通，安装各种软件和命令都踩了不少坑，北航的超算平台也各种反人类。
北航超算的相关信息：
本系统配置了 3 个登录节点，260 个 CPU 计算节点（注意！），10 个 GPU 计算节点（注意！），一套 1.8P 共享存储。所有节点通过 100Gb/s EDR Infiniband 互联组成计算和存储网络。系统详细配置如下：
1） 登录管理节点：共 3 个登录节点。（只影响登陆）
2） GPU 计算节点：共 10 个 GPU 计算节点，每个节点配置 2 颗 Intel Golden 6240 系列处理
器（每个卡有18核处理器），共 36 个物理核，384GB 内存，8 个 NVIDIA V100 GPU 卡。
3） CPU 计算节点：共 260 个 CPU 计算节点，每个节点配置 2 颗 Intel Golden 6240 系列处
理器（每个卡18核处理器），共 36 物理核，384GB 内存（注意）（根据 IB 网络配置，单个作业最多使用 160 个计算节
点）。
4） 并行存储系统：配置一套 DDN 并行存储系统，共配置 1.8PB 存储容量。
5） 管理网络：配置一套千兆管理网；
6） 带外管理网络：配置一套千兆带外管理网；
7） 计算网络：配置一套 100Gb/s 高速 Infiniband 网。
总共电脑数有几个不知道啊。
- nn表示计算节点数，这里你可以自己选择，因为cpu最多160个计算节点
计算节点数/计算机数 = 每台计算机运行节点数
为什么要分配节点数，因为一台计算机的内存有限，最常见的原因是求解器所需的内存太多，无法在一台主机上运行。系统最大384GB 内存
nnhost表示要在每个主机计算几个节点。
- np表示核数
表示每个计算节点使用可用的内核数
nn*np 是活动核数（每个节点不要超过36个）
理论上可以用160个计算节点，于是160✖️36=5760。
也就是每个计算节点最多可以申请36个核，cpu最多申请活动的总核数可以到达5760个。但实际不可能让你申请那么多计算节点，全校这么多人在用。
例如：
使用4个计算节点（nn=4），每个计算节点分配8个核（np=8，np*nn=32），每个计算机分配2个节点（nnhost=2）
这样实际就用了两台计算机
使用2个计算节点（nn=2），每个计算节点12个核（np=12，np*nn=24），每个计算机分配1个节点（nnhost=1）
这样也是用了两台计算机
这些是我的观点，有错误可以指出
例子：
/gs/home/xx/Comsol/comsol56/multiphysics/bin/comsol batch -nn 1 -nnhost 12 -np 12 -inputfile ${INPUTFILE} -outputfile ${OUTPUTFILE} \
-batchlog $
表示1个计算节点，每个主机计算12个节点数，每个节点都使用12个内核
分布式计算就是希望通过指派多个节点，并行计算程序（我在瞎说，不严格就当没看到）
但并不是核越多越好问题的规模会影响加速效果。对于非常大型的模型（如几百万个自由度），加速效果会更好。如果您使用非常小的模型，则在使用多个内核时，加速会受到限制。此外，可能达到的最大加速效果还受到算法非并行部分的限制。
运行时长例子：针对同一套matlab程序，有
#SBATCH -N 4 # 使用 4 个节点
#SBATCH -n 20 # 共使用 20 个进程（cpu 核）
#SBATCH --ntasks-per-node=5 # 每个节点启动 5 个进程
结果为：
Elapsed time is 97.883870 seconds.
#SBATCH -N 4 # 使用 4 个节点
#SBATCH -n 60 # 共使用 60 个进程（cpu 核）
#SBATCH --ntasks-per-node=15 # 每个节点启动 15 个进程
结果为：
Elapsed time is 94.403575 seconds.

程序安装
安装的例子b站很多，可以多搜索多试试
一、Matlab
北航超算居然没有安装matlab，滑天下之大稽，居然有高校超算不装matlab的，真是闻所未闻....
事先说明，csdn有个北航安装超算的帖子，本人亲测无用，因为是用X11的，下不到X11的我直接选择静默安装。
那个帖子如下：https://blog.csdn.net/weixin_41692946/article/details/120971906
我的安装历程：
下载Linux版 matlab，这里都用2019.链接在 https://pan.baidu.com/s/17fBd0XX0At5cevaLzxUuhQ
注意把里面的破解包也下过来 密码：qalz本地解压后上传服务器端，你要直接用服务器7zip也行
将文件上传的地方进行修改权限，你可以选择手动修改，直接改为777
捕获.JPG
或者通过命令修改
chmod 777 /路径/install
好的，修改命令的指令你会了。你需要修改这几个文件的权限：
/gs/home/XX/matlab/R2019b_Linux/install
/gs/home/XX/matlab/R2019b_Linux/bin/glnxa64/install_unix
/gs/home/XX/matlab/R2019b_Linux/sys/java/jre/glnxa64/jre/bin
修改完了；当然你也可以对所有文件修改权限，注意要用resursively
开始安装
直接cd到安装包所在文件夹/gs/home/XX/matlab/R2019b_Linux/，然后 ./install
结果： 报错
Error: Installation cannot proceed. You may either:
1. Set an X11 display, and restart the install process
2. Use the silent install feature by specifying the -mode silent option
后来发现：必须静默模式下安装，因为没有可视化界面
- 修改后命令 ./install -mode silent
接着报错：说 the Installer cannot be run from inside the DVD directory. Change to your home directory and execute this command.
百度之，发现不能直接在挂载的目录即matlab文件夹下运行./install，可以返回上级目录运行./matlab/install
接着回上一层文件夹/gs/home/XX/matlab/
然后 ./install -mode silent -agreeToLicense yes -fileInstallationKey 09806-07443-53955-64350-21751-41297
接着报错：
Error: 不能在home文件创造xx（英文反正这个意思）
确实，我没有根目录的权限也不可能装在学校根目录下啊，得手动修改安装路径只能自己打开安装包信息看看了，在/gs/home/xx/matlab/R2019b_Linux/install_input.txt
## SPECIFY INSTALLATION FOLDER
##
## Example:
## (Windows) destinationFolder=C:\Program Files\MATLAB\RXXXX
## (Unix) destinationFolder=/usr/local/RXXXX
## (Mac) destinationFolder=/Applications
##
## Set the desired value for destinationFolder and
## uncomment the line.
# destinationFolder=
## SPECIFY FILE INSTALLATION KEY
##
## Example: fileInstallationKey=xxxxx-xxxxx-xxxxx-xxxxx.....
##
## Set the desired value for fileInstallationKey and
## uncomment the line.
##
# fileInstallationKey=
好吧，把安装的绝对路径及序列号加上
最终安装命令：
./R2019b_Linux/install -mode silent -agreeToLicense yes -fileInstallationKey 09806-07443-53955-64350-21751-41297 -destinationFolder /gs/home/xx/Matlab
好，这下成功安装中了，接着和师弟出去吃饭了，回来一看傻眼了，被程序kill了
- 询问超算老师，得知是负载过高....
忍住吐槽的心（安装个matlab也能负载过高，你这可是超算啊），把原来的安装残余文件删除（不然这些残余文件会影响下次安装）
自己写个脚本提交计算节点好了
于是我把脚本放在这里了, 建立了脚本 install_mat.sh，注意要改成 LF格式。不然提交会报错说识别不了\n\r.
(Batch script contains DOS line breaks (\r\n))
#!/bin/bash
#SBATCH -J std
#SBATCH -p cpu-normal
#SBATCH -N 1
#SBATCH -n 20
#SBATCH -t 10000:00
#SBATCH --mail-type=all
#module load intel/17.0.7-thc
cd ${SLURM_SUBMIT_DIR}
mkdir ${SLURM_JOBID}
export TMPDIR=${SLURM_SUBMIT_DIR}
./R2019b_Linux/install -mode silent -agreeToLicense yes -fileInstallationKey 09806-07443-53955-64350-21751-41297 -destinationFolder /gs/home/xx/Matlab
make
make install
提交完，系统又卡bug了，不过这次是官方的问题
美滋滋出去吃个夜宵
安装OK的标志：查看文件slurm-4537276.out
会有信息
Exiting with status 0
End - Successful.
Finished
make: *** No targets specified and no makefile found. Stop.
make: *** No rule to make target `install`. Stop.
妥了
- 回来一看，准备打开，想起来还需要激活，于是看下前面crack的文件 readme.txt
standalone:
- Install choosing the option "Use a File Installation Key" and supply the following FIK
09806-07443-53955-64350-21751-41297
- To install Matlab Production Server,using this
40236-45817-26714-51426-39281
- Use license_standalone.lic to activate,
or copy license_standalone.lic to %installdir%\licenses\ ,and run matlab without activation
- after the installation finishes copy the folders to %installdir% to overwriting the originally installed files
好，告诉我们两个事：
需要在你安装的目录新建一个licenses的文件夹，把 license_standalone.lic 放进去
把 libmwlmgrimpl.so 这个文件取代安装位置bin/glnxa64/matlab_startup_plugins/lmgrimpl/中的同名文件，记着取代之前该原始文件权限777
两个文件都搞定以后，直接cd到安装好的matlab路径（在bin文件位置）：
./matlab
（网上说需要./matlab -chome/usr/matlab2016/licenses/license_standalone.lic， 但是我直接matlab就打开了，前面也说直接copy就行，不知道为啥）
出现以下文字

成功打开
有些可能需要清空系统的缓存，命令rm -r -f ~/.matlab/（我没试过，总之看rp）
- 提交作业
两种方式： - 采用后台计算，并不是提交到计算节点上，cd到作业的目录，然后输入
nohup matlab -nodesktop -nosplash < test.m >running.log 2>running.err
这种方法不推荐，因为不能调度服务器的资源
- 采用脚本提交作业
首先要在之前环境变量中加入matlab路径。首先先新建文本文件.bashrc
在文件中加入
# .bashrc
# Source global definitions
if [ -f /etc/bashrc ]; then
. /etc/bashrc
fi
# export SYSTEMD_PAGER="/gs/home/xx/Matlab/bin/matlab"
export PATH="/gs/home/baoyue/Matlab/bin/:$PATH"
# Uncomment the following line if you don't like systemctl's auto-paging feature:
# export SYSTEMD_PAGER="/gs/home/xx/Matlab/bin:$PATH"
# User specific aliases and functions
然后接着激活，在命令行中输入
. ~/.bashrc
激活后即可使用。
于是采用matlab提交作业脚本进行提交，提交脚本如官方指导，奉上
matlab_slurm.sh
#!/bin/bash
#SBATCH -J test # 任务名字是 test
#SBATCH -p cpu-normal # 提交到 normal 分区
#SBATCH -N 4 # 使用 4 个节点
#SBATCH -n 20 # 使用 20 个进程（cpu 核）
#SBATCH --ntasks-per-node=5 # 每个节点启动 5 个进程
#SBATCH -t 10000:00 # 任务最大运行时间是 10000 分钟
#SBATCH -o test.out #正确的输出
#SBATCH -e err.out #错误的输出
# module add matlab # 添加 MATLAB 模块，由于在超算中我们使用的是自己的matlab程序，所以这里不载入环境
matlab -nodesktop -nosplash -nodisplay -r "test_" # 使用 MATLAB 运行当前文件夹中的 Test.m 文件
Bingo!

二、Comsol
Comsol安装并无大碍，非常顺利，我的是6.0版本
1 如前一样。
修改权限
2 按照流程安装comsol，其他没啥可说的。因为comsol需要无图形界面安装
需要修改 setupconfig.ini 文件，主要是一个静默安装、一个同意条款、安装文件路径、然后破解许可证文件路径。
#
# COMSOL automated installation answer file.
#
# Usage:
# 1) copy this file and modify the properties below
# 2) run setup -s <path to modified setupconfig.ini file>

# 1: The installation was completed but there was at least one warning.
# 2: The installation was completed but there was at least one error.
# 3: The installation was completed but there was at least one fatal error.

安装完成即可

三、abaqus
基本需要多试几个节点
1. 将abaqus安装文件上传，首先破解license
2. 在安装目录下输入 ./lmgrd -c abaqus.lic
3. 安装成功后进入abaqus安装，首先创建一个文件夹，并cd到该文件夹
4. 通过chmod + x /setup文件位置（安全打开）
5. 接着csh /setup文件位置(可能需要创建一个scratch的文件位置，输入就好了）
6. 再chmod + x +install.bin文件位置（直接拷贝上面的）
7. 接着csh /setup文件位置
8. enjoy安装
9. 可能需要清空系统的缓存，命令rm -r -f ~/.abaqus/（我没试过）
10. 一个节点安装不成试用多个，这个安装真的靠rp
提交文件就不放在这里了，网上到处都是
参考：来自视频
四、安装解压缩程序
在超算安装其他源程序如p7zip
1. 下载需要的文件（可以用超算直接下载，超算联网的）
2. chmod打开文件，然后注意用文档查看install文件（注意修改安装位置）,和前面装matlab类似
3. make&make install或者./install

五、一些小白的命令
$ squeue -u xx 查看自己任务
$ scontrol show job 280675 查看自己任务详情
$ sbatch xx.sh 提交任务
./ 指在当前目录
pwd 显示文件位置
cd 进入用户主目录
$ du -hs /gs/home/xx/ 查看容量
$ rm -rf 路径 删除文件夹
Ctrl+c和ctrl+z都是中断命令,但是他们的作用却不一样.
Ctrl+c是强制中断程序的执行。
Ctrl+z的是将任务中断,但是此任务并没有结束,他仍然在进程中他只是维持挂起的状态。
cd进入文件（不可在Ln上直接提交,需要cd进入文件夹里面提交）
将xx.sh中的文件名与提交节点修改，将inp文件与该文件一起上传至文件区，然后使用$ sbatch xx.sh提交即可。
可同时计算三个作业。其他都会排队。
