I need to provide a "back-up" cluster to our main cluster, say 4 nodes with head and NFS DATA. We primarily run lisp, perl and shell in a parallel, asynchronous, parallel processing mode - no hosting, serving or anything like that. Can anyone recommend any cost-effective approaches, from buying time on another cluster, to renting a dedicated cluster on a hosting service, to purchasing low-cost but reliable hardware, etc. Your experiences much appreciated.
