Single System Image?
#5
Yep. Those are all pretty useful, but it's all either High Availability (failover), instead of High Perfomance (parallel processing), and all the HPC stuff is based on code requiring parallel API calles (mpich, etc.) instead of Single System Image setups. Beowulf, for example, is parallel but not SSI. The software still sees each node as a separate node. The idea behind Single System Image is none of the HP stuff needs new API calls written into the software. Unmodified multi-threaded applications see the whole cluster as a single system, rather than a cluster of nodes, and can just use it as such.

Maybe there's something already built into the kernel to handle this? Kerrighed was a stack of kernel loadable modules and config files. I'm not quite sure how OpenSSI worked. The setup instructions are lacking, to be generous.
