Configuring SGE


There are 2 ways to configure SGE with the CLI, by predefined text files or by templates.

qconf -A|-M textfile

will read the information from the given textfile.

There are usually 4 actions one can take : add, modify, delete and show configurations.

qconf -a|-m|-d|-s

There are 3 kind of host types in SGE, master, submit and execution.

qconf -ae

will open a template file for execution hosts, do the changes and write back the file, that's everything!

qconf -mq alicgrid

will open the configuration for the queue alicegrid.

Modifying SGE


One thing that is different from LSF is the concept of queue instances, this is just like a queue on a host. Unlike as in LSF one does not close a queue or a host, instead one has to close all queue instances belonging to a queue or a host :

qmod -d alicegrid@'*' 'closes' the queue alicegrid

qmod -d '*'@lxb500 'closes' lxb500

Disabeling the complete cluster is done by :

qmod -d '*'@'*'

The advantage of this concept is that these queue instances can act independently from each other on queue and host level.

E.g. if /var/gsi/gridhome is missing for some reasons on lxb500 and the GRID jobs will fail there, there is no need to close the complete node, but only the queue instance.
