As part of an effort to design and implement a Fortran compiler on the ILLIAC IV, an extended Fortran, called IVTRAN, has been developed. This language provides a means of expressing data and control structures suitable for exploiting ILLIAC IV parallelism. This paper reviews the hardware characteristics of the ILLIAC and singles out unconventiona features(More)
The National Software Works (NSW) is a significant new step in the development of distributed processing systems and computer networks. NSW is an ambitious project to link a set of geographically distributed and diverse hosts with an operating system which appears as a single entity to a prospective user. An initial version of NSW spanning TENEX, MULTICS,(More)
The unconventional design of the ILLIAC-IV requires unconventional optimization techniques. Conventional techniques focus on the program. Since conventional hardware executes one instruction at a time, greater efficiency is obtained by reducing the number of instructions executed. Elimination of common subexpressions and literal computations, removal of(More)
We have read with much interest the paper &#8220;Automatic Segmentation of Cyclic Program Structures Based on Connectivity and Processor Timing&#8221; by T. C. Lowe [<italic>Comm. ACM 13</italic>, 1 (Jan. 1970), 3-6, 9], and we congratulate the author on the clarity of his exposition. However, we're afraid we must question the technique he describes.
For the past several years various investigators at Lawrence Radiation Laboratory, Livermore have been conducting studies in computer graphics and man-machine interaction. These studies have included aids to numerical analysis,<supscrpt>1,2</supscrpt> photographic input and picture processing,<supscrpt>3,4</supscrpt> and computer-aided circuit(More)
