[Gate-users] cluster configuration

[Simon Stute]

Hi all,

In our team we deployed Gate on 2 different clusters. Both Linux, one with
Fedora and Ubuntu for the second, and both with the Condor cluster utility.

The Fedora distribution is changing every 6 months, so if you want to always
have an up-to-date system it is not recommended, because it is very annoying
when you have to reinstall everything on multiple machine...
The Ubuntu community produces some LTS (Long Time Support) distributions
that permit you to keep your system up-to-date for at least 2 years (to be
verified), and it is pretty easy at the end of this period to upgrade your
installation to the new one without having to reinstall all stuff.
We have no experience at all with Scientific linux.

I think that your choice is strickly dependent on what you want to do with
your machines. Do you plan to use its for other things than just running
Gate on it ? Do you want to run other programs that need to follow the gcc
evolution for example ? And what clustering utility do you want to use ?

Concerning this point, we always used and use Condor. It is pretty easy to
install and configure if you have few Linux and Network knowledge. It allows
to do a lot of things (from basic to very twisted). And the Cluster_Tools
from GATE totally support Condor. The Condor team distributes either some
binaries for few distributions that are very easy to install (then you have
to configure few things as I said), or the source code if you don't find
yours.

When we installed Condor on Fedora, there were Fedora binaries, but now
there aren't anymore...
And for Ubuntu, we take (as advised in condor forums) the RedHat enterprise
binaries that are still working well !

Hope these informations could be useful,
Cheers,
Simon
