Batcher Odd-Even Mergesort For Eight Inputs
Kenneth Edward Batcher (December 27, 1935 – August 22, 2019) was an American academic who was emeritus professor of Computer Science at Kent State University. He also worked as a computer architect at Goodyear Aerospace in Akron, Ohio for 28 years. Background Kenneth Edward Batcher was born on December 27, 1935 in Queens, New York, to Lois and Ralph Batcher. His parents met at Iowa State University and later relocated to New York City after graduation. His father, Ralph R. Batcher, was the Chief Engineer of The A. H. Grebe Radio Company until its bankruptcy in 1932. Batcher graduated from Brooklyn Technical High School, and then from Iowa State University with B.E. degree in 1957. In 1964, Batcher received his Ph.D. in electrical engineering from the University of Illinois. Batcher died in Stow, Ohio on August 22, 2019, at the age of 83. Career and achievements Among the designs he worked on at Goodyear were the: * Massively Parallel Processor (16,384 custom bit-serial p ...

Computer Science
Computer science is the study of computation, information, and automation. Computer science spans Theoretical computer science, theoretical disciplines (such as algorithms, theory of computation, and information theory) to Applied science, applied disciplines (including the design and implementation of Computer architecture, hardware and Software engineering, software). Algorithms and data structures are central to computer science. The theory of computation concerns abstract models of computation and general classes of computational problem, problems that can be solved using them. The fields of cryptography and computer security involve studying the means for secure communication and preventing security vulnerabilities. Computer graphics (computer science), Computer graphics and computational geometry address the generation of images. Programming language theory considers different ways to describe computational processes, and database theory concerns the management of re ...

Goddard Space Flight Center
The Goddard Space Flight Center (GSFC) is a major NASA space research laboratory located approximately northeast of Washington, D.C., in Greenbelt, Maryland, United States. Established on May 1, 1959, as NASA's first space flight center, GSFC employs about 10,000 civil servants and contractors. Named for American rocket propulsion pioneer Robert H. Goddard, it is one of ten major NASA field centers. GSFC is partially within the former Goddard, Maryland, Goddard census-designated place; it has a Greenbelt, Maryland, Greenbelt mailing address.CENSUS 2000 BLOCK MAP: GODDARD CDP (PDF).

Bitonic Sorter
Bitonic mergesort is a parallel algorithm for sorting. It is also used as a construction method for building a sorting network. The algorithm was devised by Ken Batcher. The resulting sorting networks consist of O(n\log^2(n)) comparators and have a delay of O(\log^2(n)), where n is the number of items to be sorted. This makes it a popular choice for sorting large numbers of elements on an architecture which itself contains a large number of parallel execution units running in Lockstep (computing), lockstep, such as a typical Graphics processing unit, GPU. A sorted sequence is a monotonically non-decreasing (or non-increasing) sequence. A ''bitonic'' sequence is a sequence with x_0 \leq \cdots \leq x_k \geq \cdots \geq x_ for some k, 0 \leq k arr[l]) OR (bitwiseAND (i, k) != 0) AND (arr[i] < arr[l]) ) swap the elements arr[i] and arr[l] See also * Batcher odd–even mergesort * Pairwise sortin ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seymour Cray Computer Engineering Award
The Seymour Cray Computer Engineering Award, also known as the Seymour Cray Award, is an award given by the IEEE Computer Society, to recognize significant and innovative contributions in the field of supercomputer, high-performance computing. The award honors scientists who exhibit the creativity demonstrated by Seymour Cray, founder of Cray Research, Cray Research, Inc., and an early pioneer of supercomputing. Cray was an American electrical engineer and supercomputer architect who designed a series of computers that were the fastest in the world for decades, and founded Cray Research which built many of these machines. Called "the father of supercomputing," Cray has been credited with creating the supercomputer industry. He played a key role in the invention and design of the UNIVAC 1103, a landmark high-speed computer and the first computer available for commercial use. In 1972 the IEEE presented Cray with the Harry H. Goode Memorial Award for his contributions to large-scale co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
