Ubuntu上安装torque过程

 过程参考(以及基本翻译自)此文:https://jabriffa.wordpress.com/2015/02/11/installing-torquepbs-job-scheduler-on-ubuntu-14-04-lts/ 和此文: https://linuxcluster.wordpress.com/2012/04/01/enabling-torque-for-email-notification/ .

此过程会将当前计算机当作server, compue node, scheduler and submission host.

Step 1: 从Ubuntu上安装Torque

apt-get install torque-server torque-client torque-mom torque-pam

　　这儿下载安装的是老版本Torque-2.4.16.一路Yes即可.

Step 2: 关闭当前开启的默认服务

/etc/init.d/torque-mom stop
/etc/init.d/torque-scheduler stop
/etc/init.d/torque-server stop
pbs_server -t create

　　以及:

killall pbs_server

　　这一步很重要,否则接下来所做的修改将在下一次pbs_server重启后被覆盖.

Step 3: 因为Panther当前没有FQDN只有IP, 所以选了个Domain Name为panther.ncsu.

(注: 按照参考博客的说法,这儿需要选一个两单词的server.domain形式的domain name, 否则后文可能会遇到问题.)

echo panther.ncsu > /etc/torque/server_name
echo panther.ncsu > /var/spool/torque/server_priv/acl_svr/acl_hosts
echo root@panther.ncsu > /var/spool/torque/server_priv/acl_svr/operators
echo root@panther.ncsu > /var/spool/torque/server_priv/acl_svr/managers

　　并且在/etc/hosts中加入此行:

10.123.32.** panther.ncsu

　　

Step 4: 将计算机本身当作compute node

echo "panther.ncsu np=4" > /var/spool/torque/server_priv/nodes

　　这儿可根据实际情况修改np

告诉Mom_nodes compute node的具体位置:

echo panther.ncsu > /var/spool/torque/mom_priv/config

Step 5: 重启torque服务

/etc/init.d/torque-server start
/etc/init.d/torque-scheduler start
/etc/init.d/torque-mom start

Step 6: 设置PBS参数

qmgr -c 'set server scheduling = true'
qmgr -c 'set server keep_completed = 1000' #最长时间1000小时
qmgr -c 'set server mom_job_sync = true'
qmgr -c 'create queue std' #创建std queue
qmgr -c 'set queue batch queue_type = execution'
qmgr -c 'set queue batch started = true'
qmgr -c 'set queue batch enabled = true'
qmgr -c 'set queue batch resources_default.walltime = 10:00:00'
qmgr -c 'set queue batch resources_default.nodes = 1'
qmgr -c 'set server default_queue = std'

 以及设置submission pool:

qmgr -c 'set server submit_hosts = panther'
 qmgr -c 'set server allow_node_submit = true'

 上面选了domain name为panther.ncsu,这儿需要选择其name,panther为submission pool

Step 8: 提交测试任务

#! /bin/bash

#PBS -q std
#PBS -m bea
#PBS -M *****@foxmail.com
#PBS -j oe
#PBS -o oe.$PBS_JOBID
#PBS -l walltime=1000:00:00
#PBS -N arch-data

echo -e "

#export OMP_NUM_THREADS=1

#cd /lustre/or-hydra/cades-virtues/z8j/run/ZrH2/vasp/supercell/disps/disp-001/
cd $PBS_O_WORKDIR

date

#mv fropho_calc/ /home/zjyx/data_drive/data-archived/ZrH2/
#cp pbs.sh /home/zjyx/data_drive/data-archived/ZrH2/
echo -e "

Solutions: (http://torqueusers.supercluster.narkive.com/Ut2n70R1/host-key-verification-failed: Host key verification failed)

Just try to delete ~/.ssh/known_hosts, and ssh between different nodes set up by torque. In my case, I did ssh panther.ncsu, ssh localhost, ssh Panther, and ssh panther.
