The present invention relates to a server-processor hybrid system that comprises (among other things) a set (one or more) of front-end servers (e.g., mainframes) and a set of back-end application optimized processors. Moreover, implementations of the invention provide a server and processor hybrid system and method for distributing and managing the execution of applications at a fine-grained level via an I/O-connected hybrid system. This method allows one system to be used to manage and control the system functions, and one or more other systems to co-processor.
