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