Exclude knots in SunGridEngine

Using SGE I can exclude a node called "node6" with the option:

#$ -l h=!node6

Question: Does anyone know how to extend this to more than one node? I really can't find a good HowTo and I'm tired of guessing. Thanks!

Solution

  • You can use a wildcard expression to exclude some nodes. For example if you have nodes called node1, node2 ... nodeX; to exclude node2 to node5 you can use :

     #$ -l h='!node[2-5]'

    or to exclude several nodes :

     #$ -l h='!(nodeP|nodeQ|...|nodeR)' //P,Q,R in [1,X]

    Now just find the pattern which matches all the nodes you want to exclude.

    Else, you can use a resource quota. To perform that, create a resource quota :

    qconf -arqs disabledHostsResourceQuota

    Edit this resource quota to allow a hostgroup (let's call it disabledHosts) to prevent jobs from running :

    {
   name         disabledHostsResourceQuota
   description  resource quota to disable some hosts
   enabled      TRUE
   limit        hosts {@disabledHosts} to slots=0
}

    Then create your hostgroup :

    qconf -ahgrp  disabledHosts

    and in the "hostlist" field, add all the hosts you want to disable. You can then submit your job without any option, that should do the trick.
