Example SGE master node installation

  • Hostname: NODENAME


Remove entry (or pointing to the hostname from /etc/hosts/	localhost

# The following lines are desirable for IPv6 capable hosts
::1     ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

SGE master installation

Copy the content of this repo in the host, and with sudo, do:

mkdir /opt/sge6-2/
cp ge62u5.tar.gz /opt/sge6-2/
cd /opt/sge6-2/
chmod +x

We have in the folder the following structure:

├── 3rd_party
├── bin
├── catman
├── ckpt
├── doc
├── dtrace
├── examples
├── ge6.2u5
├── ge62u5.tar.gz
├── include
├── install_execd
├── install_qmaster
├── inst_sge
├── lib
├── man
├── mpi
├── pvm
├── qmon
├── start_gui_installer
├── util
└── utilbin

Now we proceed with the SGE master installation:

cd /opt/sge6-2/

The following error is expected, everything is fine:

util/sgeCA/sge_ca: 1: eval: lx24-amd64=/opt/sge6-2/lib/lx24-amd64:-amd64: not found
util/sgeCA/sge_ca: 1749: export: lx24-amd64: bad variable name

To use the cluster commands (qsub, qstat, etc.), some variables should be included in the environment. This should be included in the .bashrc of the user that will use the cluster.

source /opt/sge6-2/default/common/

To start the sgemaster process:

   starting sge_qmaster

Then, qstat -f should not show any error:

$ qstat -f

SGE master setup

We will add the host as an execute node:

qconf -ae

Include here the hostname:

hostname              NODENAME
load_scaling          NONE
complex_values        NONE
user_lists            NONE

projects              NONE
xprojects             NONE
usage_scaling         NONE
report_variables      NONE

We create now the host list:

qconf -ahgrp

Add the host list @allhosts with this host:

group_name @allhosts
hostlist NODENAME

Add a new queue:

qconf -aq

Change the values properly:

qname                 all.q
hostlist              @allhosts
seq_no                0
load_thresholds       np_load_avg=1.75
suspend_thresholds    NONE
nsuspend              1

Add user, in this case, NEWUSER:

qconf -auser
oticket 0
fshare 0
delete_time 0
default_project NONE

Add a new user list, with this NEWUSER:


We should modify the queue to include this user list:

qconf -mq all.q
notify                00:00:60
owner_list            NONE
user_lists            NEWUSERS
xuser_lists           NONE
subordinate_list      NONE

Launch the execute daemon (sgeexcd):

$:/opt/sge6-2/default/common# ./sgeexecd 
   starting sge_execd

If the queue is in some weird state, you can run to clean its state:

qmod -c all.q@NODENAME

We can restart the services, just in case:

$: cd /opt/sge6-2/default/common# 
$: ./sgeexecd stop
   Shutting down Grid Engine execution daemon
$: cd /opt/sge6-2/default/common
$: ./sgemaster stop
   shutting down Grid Engine qmaster
$: cd /opt/sge6-2/default/common
$: ./sgemaster start
   starting sge_qmaster
$: cd /opt/sge6-2/default/common
$: ./sgeexecd start
   starting sge_execd

Add the host to the submit hosts' list:

qconf -as NODENAME
NODENAME added to submit host list
