Application of the Illiac IV Computer to Problems in the Numerical Calculation of Electromagnetic Fields.

Abstract

A brief description of the ILLIAC IV computer is given. Two running programs, HEMP and SC, were coded in ILLIAC IV assembly language and the execution times and programming considerations are discussed. The ILLIAC IV codes were estimated to run in the neighborhood of one and one-half to two orders of magnitude faster than presently being run. ILLIAC IV processing element efficiency ranged from 2 percent efficient to 100 percent efficient over various sections of the codes with an average for the two codes of approximately 60 percent. Although these figures vary greatly, it is concluded that the problems lend themselves to the ILLIAC IV with a reasonable degree of effectiveness. Memory size is somewhat limited and causes concern in terms of INPUT/OUTPUT and size of expanded problems. However, problems several times the size of those presently being run can be easily handled.
