Process for executing procedure and system therefor

PURPOSE: To call a calling destination process without necessitating any context switching. CONSTITUTION: An outside procedure calling (XPC) is one function in a distributed data processing environment, and a local or remote procedure from the point of view of a calling origin process (request origin sled 38) is called and executed without necessitating to locally or remotely operate complete context switching between processes (tasks), and the result can be returned to the calling origin process as necessary. One sub-routine is related with each processing node of the distributed data processing environment, and this sub-routine is encoded so as to be directly accessed and executed in each processing sled of a parallel job.
