A Logic-in-Memory Computer

Abstract: If, as presently projected, the cost of microelectronic arrays in the future will tend to reflect the number of pins on the array rather than the number of gates, the logic-in-memory array is an extremely attractive computer component. Such an array is essentially a microelectronic memory with some combinational logic associated with each storage element. A logic-in-memory computer is described that is organized around a logic-enhanced ``cache'' memory array. Used as a cache, a logic-in-memory array performs as a high-speed buffer between a conventional CPU and a conventional memory. The effect on the computer system of the cache and its control mechanism is to make the main memory appear to have all of the processing capabilities and almost the same performance as the cache. Operations within the array are naturally organized as operations on blocks of data called ``sectors.'' Among the operations that can be performed are arithmetic and logical operations on pairs of elements from two sectors, and a variety of associative search operations on a single sector. For such operations, the main memory of the computer appears to the program to be composed of a collection of logic-in-memory arrays, each the size of a sector. Because of the high-speed, highly parallel sector operations, the logic-in-memory computer points to a new direction for achieving orders of magnitude increase in computer performance. Moreover, since the computer is specifically organized for large-scale integration, the increased performance might be obtained for a comparatively small dollar cost.

A Mesoscale Radiation Study of the Cache Valley

Abstract: A MESOSCALE RAD IATION STUDY OF THE CACHE VALLEY by Nolasco G. Baldazo, Master of Science Utah State University, 1970 Major Professor: Dr . Inge Dirmhirn Depar tment: Soils and Me teoro logy The radiation climate of Cache Valley was es tablished f rom the con tinuous recordings of global and diffuse sky r adiation at Utah State University campus from June 1968 to July 1969 and August 1968 to July 1969, respec t ively. The influence of topographic features during summer and winter conditions a t seven representative locations running on an east-west direction across the valley were dete rmined by making shor t t erm measurements on clear days. A comparison of the clear day average global radiation on app r oximate dates of the same solar declination shows higher values during late winter and spring than t he values during late summer and autumn. This is mainly the influence of the higher atmospheric water vapor during the wa rmer months. An interesting fact is, that not only the direct , but also the scattered radiation shows higher values during t he spring months . This is caused by additional reflection from the snow-covered mountain slopes . In the curve showing th e distribution of the diffuse sky radiation on completely cloudy days, t he effect of the mul t iple reflection between the ground surface and t he bases of clouds is very prominent in the period when there is snow on

An Unusual Cache from the Wyoming Valley, Pennsylvania

Abstract: In 1964, topsoil removal operations in the Wyoming Valley, Pennsylvania, exposed a large cache of beads and shell objects. There is evidence that many of the beads and objects were originally strung as necklaces or belts, but these were destroyed when the discoverer washed the material. An attempt is made to reconstruct the contents of the cache and to determine its approximate age.

A Client-Side Cloud Cache Replacement Policy

Abstract: To deliver data-centric cloud computing services heavily relies on data networks between cloud providers and consumer premises. The continuous and rapid growth of data hosted in external private clouds accelerates downstream network-bandwidth saturation and public cloud data-out overspends. The consumer-initiated replication of cloud data to consumer locality is a solution and known as clientside cloud caching. This paper presents the core mechanism of the cloud caching, called Cloud cache replacement policy. Simulations shown that 1) Cloud saved network bandwidth, data-out charge and data loading time; 2) even Clouds performance minima outperformed three well-known web cache replacement policies across all performance metrics for almost all test cases; 3) Cloud importantly attain optimal hit and byte-hit ratios without sacrificing one to the other.

A Study of the Use of Instructional TV Programs in Logan City and Cache County Schools 1969-1970

Abstract: A Study of the Use of Instructional TV Programs in Logan City and Cache County Schools 19691970 by Gary R. Saville, Haster of Science Utah State University, 1970 Hajor Professor: Dr. Burre 11 F. Hansen Depar tment: Speech A sampling of teachers from two school districts was interv iewed to determine the amount of use and factors affecting utilization of ITV programs in the classroom. The findings revealed a hi gh percentage of t eachers using ITV programs in their classes. Physical surroundings had the grea t es t influence on TV usage. Unavailability of TV sets and poor r ecep t ion of t he TV signal hamper teachers usage of lTV . The t eachers who used lTV incorpora t ed the elements of pre-program preparation of the student : or wha t they we r e about to view and followup materials after the prog am . Most of the teachers felt that lTV was modera t ely effective as a t eaching tool.
