ORGANIZATION OF A LARGE-SCAL COMPUTER PROGRAM FOR SPACE AGE GEODESY,
Abstract
The GEO-STRETCH program is a large-scale scientific computation which fits observations of artificial earth satellites to produce a detailed picture of the earth's gravittional field and surface geometry. It is run on an IBM STRETCH computer with 48,000 64-bit words of core storage, 10 tape drives and a 2,000,000 word disk store. The large amounts of observational data availble and the number of physical parameters to be determined have necessitated novel segmentation procedures for the optimum use of core storage, and required the development of a fully automatic library procedure. In addition, the large number of operating modes required in the practical use of the program has led to a unique blend of scientific programming, software interpretive programs and large-scale data processing, which tax the capacity of the STRETCH computer to its practical limit.
