Software Parts for Elliptic PPE Software
John R. Rice · Purdue e-Pubs (Purdue University System) · 1983
We examine the question or whether very high level elliptic prob· lem solvers can be built (in theory or in practice) from a collection of software parts. In theory the answer is yes. in current practice the answer is no. because most of the required software parts are missing. The levels of software parts needed are identified and their contents outlined. There are isolated collections of parts currently available (e.g. the high level problem solving modules in ELLPACK. the low level vector processing routines in the BLAS). but· their percentage of thos~ needed is low, perhaps 10-20 percent. A set of priorities for creating the needed software parts is given and sets of software parts in the area domain processing are considered in detail. CONTENTS
