Most of these single system image clusters have used custom, fast interconnects akin to Inifinband or hypertransport to ameliorate locality issues (latency and bandwidth)... Without such, it's neigh impossible without pinning all resources for a "process" to one physical box. Good luck ever getting more than one box worth of performance or resources out of a single application instance. Hence MapReduce, actors, promises, message-passing, etc. |
