Facing a need to run large scenarios on aviation models more quickly than the one to two days currently required, the MITRE Corporation undertook an effort to reduce the execution time of one such simulation. Time and cost constraints prohibited a major rewrite of the almost one million existing lines of code, so only solutions requiring minimal changes to the code base were considered.

The paper describes a parallel proximity detection algorithm and illustrates its application to the problem of conflict detection in an aviation simulation. The algorithm invokes a previously designed sequential function in parallel, using spatial information acquired during the traversal of a quad tree, to keep the separate invocations of the function as independent as possible. The method is gen...Show More
