US Patent 7317990 Distributed processing system for subsurface operations

A method for distributed processing in a subsurface environment includes running a local program on a local computation unit, wherein the local program is configured to call a remote procedure to be executed by a remote computation unit, wherein the local computation unit and the remote computation unit are disposed in a subsurface environment; initiating a remote procedure call; executing the remote procedure on the remote computation unit, while the local computation unit performs another operation; and returning a result from the executing the remote procedure to the local computation unit.
