It might be a naive question, but I have four servers (on the same network) which I want to utilize for running a computing intensive tool. The tool itself is not designed to be run in a distributed environment (a cluster). So if I use a private cloud solution (e.g. Eucalyptus), would I be able to make the four server "virtually" look like one and run the tool on that "virtual" big server?
If this is not the right approach, then what are the solutions that can aggregate resources from different servers.
