Facilities
RCF supports a diverse collection of hardware that is here as a campus resource, and anyone on campus is welcome to apply for an account on these machines.
Access to these resources is by default shared with the rest of the user community via various job schedulers. These policies may be found on the pages for the various resources. Alternatively, a user may buy into an existing resource, acquiring 'priority access'. Finally, several machines are available via Condor for opportunistic use. This will allow users almost immediate access, but the job is subject to preemption.

Computers
Homestead - Our 32 processor SGI Origin 300 is our original machine.
PrairieFire - 128 dual processor AMD machines packed together into a small space make for one hot cluster. It also makes up our beloved PrairieFire.
Red - This cluster is the resource for UNL's US CMS Tier-2 site. It consists of 256 compute cores and 50 TB of storage.
Merritt - An SGI Altix 3700 supercomputer purchased for general use by UNL researchers.
