    In the Beginning... A Legacy of Computing at Marshall University

    This book provides a brief history of the early computing technology at Marshall University, Huntington, W.Va., in the forty years: 1959-1999. This was before the move to Intel and Windows based servers. After installation of an IBM Accounting Machine in 1959, which arguably does not fit the modern definition of a computer, the first true computer arrived in 1963 and was installed in a room below the Registrar’s office. For the next twenty years several departments ordered their own midrange standalone systems to fit their individual departmental requirements. These represented different platforms from different vendors, and were not connected to each other. At the same time, the Marshall Computer Center developed an interconnected, multi-processor environment. With the software problems of year 2000, and the I/T move to the new Drinko Library, several systems were scrapped. New systems were installed on the pc server platforms. This book includes images of the various systems, several comments from users, and hardware and software descriptions

    Using a functional language and graph reduction to program multiprocessor machines or functional control of imperative programs

    Journal ArticleThis paper describes an effective means for programming shared memory multiprocessors whereby a set of sequential activities are linked together for execution in parallel. The glue for this linkage is provided by a functional language implemented via graph reduction and demand evaluation. The full power of functional programming is used to obtain succinct, high level specifications of parallel computations. The imperative procedures that constitute the sequential activities facilitate efficient utilization of individual processing elements, while the mechanisms inherent in graph reduction synchronize and schedule these activities. The main contributions of this paper are: 1) an evaluation of the performance implications of parallel graph reduction; 2) a demonstration that the mechanisms of graph reduction can obtain multiprocessor performance uniformly surpassing the best uni-processor implementation of sequential algorithms running on a single node of the same machine, and 3) an illustration of our method used to program a real world fluid flow simulation problem

    An Automated Diagnostic Test and Tutorial Package for Basic Skills of Mathematics in Post Secondary Vocational Education of Kentucky: Construction and Validation

    The purpose of this research study was to determine characteristics of entering vocational students in Kentucky Area/State vocational schools and to develop a computerized diagnostic instrument and tutorial package for assisting students in the mastery of necessary basic skills in mathematics. After specific math skills were identified in which proficiency is required of vocational education students, item pools were constructed for each skill. The skill item pools were validated using approximately 500 public school students throughout the grades of four through eight in public schools of Harlan County, Kentucky, Lee County, Virginia, and Washington County, Tennessee. The items within each item pool were found to be statistically equivalent. Computer programs were coded in the BASIC language using the item pools to randomly select and generate a diagnostic instrument and tutorial program relevant to the basic math skills. Three randomly generated forms of the diagnostic instrument were sent to 100 students in twenty area state vocational schools of Kentucky for normalization and form validation. The diagnostic instrument showed a strong positive coefficient of reliability with an average of.95 over the three forms used in the normalization process. There was no significant difference between the mean raw scores of the three forms. A 67 percentile score was found to be the norm which was to be statistically equivalent to the Tests of Adult Basic Education (TABE) at the 8.75 grade equivalent. An experiment was conducted using vocational students at Hazard State Vocational School as subjects to determine the affects of the tutorial package on basic math skill mastery using equivalent forms of the diagnostic instrument for pretesting and posttesting. Results of the experiment indicated that the computer managed instruction tutorial package had a significant affect in increasing posttest scores of the experimental group over the control group. It was concluded that the problem of constructing a computerized diagnostic math instrument and tutorial package capable of enhancing mastery of basic math skills to assist vocational students in gaining entrance into vocational school was achieved. A recommendation was made for further research and development to use the random item pool model for other development of computer assisted instruction (CAI) software

    Corey Lammie designed mixed signal memristive-complementary metal–oxide–semiconductor (CMOS) and field programmable gate arrays (FPGA) hardware architectures, which were used to reduce the power and resource requirements of Deep Learning (DL) systems; both during inference and training. Disruptive design methodologies, such as those explored in this thesis, can be used to facilitate the design of next-generation DL systems
