Using egroup in LSF

Use egroup to generate a list of users in LSF.

Useful for when admin have large groups of users and cant be bother to program each user manually.

Create the egroup file

• in $LSF_SERVERDIR/egroup [chmod +x]

#!/bin/bash

if [ "$1" == "-m" ]; then                             #host group
    if  [ "$2" == "linux_grp" ]; then                 #Linux hostgroup
        echo "linux01 linux02 linux03 linux04"
    elif [ "$2" == "sol_grp" ]; then                  #Solaris hostgroup
        echo "Sol02 Sol02 Sol03 Sol04"
fi
else                                                 #user group
 if [ "$2" == "srv_grp" ]; then                       #srvgrp user group
        echo "userA userB userC userD"
    elif [ "$2" == "dev_grp" ]; then                  #devgrp user group
        echo "user1 user2 user3 user4"
 fi
fi

Edit lsb.users (or lsb.hosts)

egroup will be called when the GROUP_MEMBER flag contains a (!)

Begin UserGroup
GROUP_NAME       GROUP_MEMBER              USER_SHARES            #GROUP_ADMIN
ugroup1         (atlasprod) ()   #()
ugroup2         (lhcbusers) ()   #()
# The following are generated from the egroup script
srv_grp         (!) ()
dev_grp         (!) ()
End UserGroup

Begin User
USER_NAME        MAX_JOBS    MAX_PEND_JOBS
default          400         -              # default, any user/group has threshold of 100
#david           5           -
ugroup1@          100           -
ugroup2@          200           -
# The following are groups defined are above called from egroup
srv_grp@          800           -
dev_grp@          50            -
End User

Reconfig

addhost -u 
OR
badmin reconfig
