Maui server v.3.2.6p21

Prepare

It is required to install the Torque server (version 2.1.6 or version 2.3.6) before the maui scheduler packages.

administrator's script: prepare.sh

```
 
```
```
#!/bin/bash
```
```
# prepare maui
```
```
#-> start routine
```

REPO_URL="http://dgiref.d-grid.de/svn/dgiref/PROD/cf3/repl/repos/external/"

wget -O /etc/yum.repos.d/sl-dgiref.repo ${REPO_URL}/sl-dgiref.repo

```
#<- end routine
```

Install

To install Maui, the following RPMs are needed :

maui
maui-server

Install rpms from dgiref binary repository.

administrator's script: install.sh

```
 
```
```
#!/bin/bash
```
```
# install maui server
```
```
#-> start routine
```
```
# SL 5 installation:
```

yum -y install maui-3.2.6p21-snap.1234905291.5.el5.x86_64 maui-server-3.2.6p21-snap.1234905291.5.el5.x86_64

```
#<- end routine
```

Configure

By default, batch systems like OpenPBS or Torque have their own job scheduler. Normally, this is much more simple-minded than Maui; for example, in the case of OpenPBS and Torque, the default is a simple fifo scheduler. Therefore, before Maui can be used, the batch system must be told to use it.

With OpenPBS or Torque, this is accomplished setting the scheduling state of the server to False:

qmgr -c "set server scheduling = False"
qmgr -c "list server"
  ...
  server_state = Idle
  scheduling = False
  ...

The scheduling policies are defined in Maui’s configuration file : /var/spool/maui/maui.cfg

administrator's script: configure.sh

```
 
```
```
#!/bin/bash
```
```
# configure maui server
```
```
#-> start routine
```
```
HOST=`hostname -f`  
```

# In some cases the alias host name command HOST=`hostname -a` should be run. But the previous should work.

echo `sed -i "s/localhost/$HOST/" /var/spool/maui/maui.cfg`

```
 
```
```
cat >> /var/spool/maui/maui.cfg << EOF
```

# The users edginfo and rgma query Maui from the glite-CE to provide data to the InfoSystem

```
ADMIN3            edginfo edguser rgma 
```

# Set the delay to 1 minute before Maui tries to run a job again,

# in case it failed to run the first time.

```
# The default value is 1 hour. 
```
```
DEFERTIME       00:01:00 
```
```
# Necessary for MPI grid jobs 
```
```
ENABLEMULTIREQJOBS TRUE
```
```
 
```
```
EOF
```
```
 
```
```
qmgr -c "set server scheduling = False"
```
```
qmgr -c "list server"
```
```
 
```
```
#<- end routine
```

Proceed

Start service maui

administrator's script: proceed.sh

```
 
```
```
#!/bin/bash
```
```
# proceed
```
```
#-> start routine
```
```
## start maui
```
```
chkconfig maui on 
```
```
/etc/init.d/maui start
```
```
 
```
```
# MAUI can be tested with
```
```
showq
```
```
diagnose -g
```
```
#<- end routine
```
