Described is a system and method that facilitates fast and reliable synchronization of computer / file system directories. A synchronization (FastSync) subsystem operates in a discovery / enumeration phase to provide a calling client with a set of the differences between directories, and then operates in an action phase to perform operations as directed by the client to synchronize the different directories. The discovery / enumeration and action phases use parallel operation and I / O (input / output) pipelining. Multiple threads are used during enumeration to enumerate each directory's children, and enqueues each sub-directory to be handled by a new thread. During the action phase, when an operation is requested, the FastSync subsystem packages up the operation, item pointer, and context information into an internal context block and queues that packet as a work item for a process thread pool to handle.

A distributed, networked simulation system has two or more vehicle simulators that resists latency errors when the vehicles are close to each other, and is especially useful for close maneuvering training such as tanker and receiver aircraft refueling exercises or combat exercises where one aircraft closely follows another. One simulator sends the other simulator data defining the relative linear displacements and rotations between their two vehicles. The receiving simulator uses the data to maintain the relative position of the other vehicle in its local scene data based on the defined relative displacement and rotation between the vehicles. An additional simulator may simulate the boom control on the tanker using similar relative position data. The system starts relative displacement data operation when one vehicle approaches another in the virtual world, and returns to normal operation when the vehicles separate.
