ProCKSI

= System Description =

== Cluster Design ==
The cluster is assumed to have one (or more) ''master nodes'' and several ''slave nodes'' (''compute nodes'').

* The master node runs the web server, the file server, the central database server, the email server, the server for the queuing system, and the ProCKSI server itself. It can be used as a compute node, too.
* The compute nodes run the calculations.

== Backup Strategy ==

* '''Cluster master head node''':[[br]]
Results are stored on a RAID5 storage element. [[br]]
No external backup.
* '''Cluster slave compute nodes''':[[br]]
Do not contain sensible data except operating system.[[br]]
No external backup.
* '''Trac''':[[br]]
Hosts Wiki pages, SVN repository, Ticketing system, etc.[[br]]
Backup to tape system (scripts on ''much.cs.nott.ac.uk''), incremental from Monday to Friday, full dump once a week:

||'''Partition'''||'''Day''' ||
||/ ||every Tuesday ||
