How is it NOT a cluster? Its 70 Bladecenter servers hooked up together, if thats not the definition of a cluster I don't know what is. It acts as one server, you are not limited from communicating from a guy on the other side of the eve-universe. A server cluster when hooked up essentially acts like a single computer.
" The exact definition of a cluster computer will depend a little on who you ask. However, there are some general characteristics that most will agree upon.
* Consists of many of the same or similar type of machines (Heterogenous clusters are a subtype, still mostly experimental) * Tightly-coupled using dedicated network connections * All machines share resources such as a common home directory (NFS can be a problem in very large clusters, so binaries and data must be pushed to scratch on each node.) * They must trust each other so that rsh or ssh does not require a password, otherwise you would need to do a manual start on each machine. * Must have software such as an MPI implementation installed to allow programs to be run across all nodes "
