Multitasking the Code ARC3D
The CFD code ARC3D has been run on a CRAY X-MP/48 computer at the CRAY Research, Inc. headquarters in Mendota Heights, Minnesota. The CRAY multitasking system was invoked in order to utilize all four processors and sharply reduce the wall clock rim time. This paper discusses the techniques used to modify the code for this run and analyzes the achieved speedup.
