Examining the Viability of FPGA Supercomputing
1 Examining the Viability of FPGA Supercomputing Stephen D. Craven and Peter Athanas Bradley Department of Electrical and Computer Engineering Virginia Polytechnic Institute and State University Blacksburg, VA 24061 USA email: {scraven,athanas}@vt.edu Abstract—For certain applications, custom computational hardware created using field programmable gate arrays (FPGAs) produces significant performance improvements over processors, leading some in academia and industry to call for the inclusion of FPGAs in supercomputing clusters. This paper presents a comparative analysis of FPGAs and traditional processors, focusing on floating- point performance and procurement costs, revealing economic hurdles in the adoption of FPGAs for general High-Performance Computing (HPC). Index Terms— computational accelerator, digital arithmetic, Field programmable gate arrays, high- performance computing, supercomputers. I. INTRODUCTION Supercomputers have experienced a recent resurgence, fueled by government research dollars and the development of low-cost supercomputing clusters. Unlike the Massively Parallel Processor (MPP) designs found in Cray and CDC machines of the 70s and 80s, featuring proprietary processor architectures, many modern supercomputing clusters are constructed from commodity PC processors, significantly reducing procurement costs. In an effort to improve performance, several companies offer machines that place one or more FPGAs in each node of the cluster. Configurable logic devices, of which FPGAs are one example, permit the device’s hardware to be programmed multiple times after manufacture. A wide body of research over two decades has repeatedly demonstrated significant performance improvements for certain classes of applications when implemented within an FPGA’s configurable logic [1]. Applications well suited to speed-up by FPGAs typically exhibit massive parallelism and small integer or fixed-point data types. -
Einstein's Geometrical Versus Feynman's Quantum-Field
Universe 2020, 6(11), 212; doi:10.3390/universe6110212 Einstein’s Geometrical Versus Feynman’s Quantum-Field Approaches to Gravity Physics: Testing by Modern Multimessenger Astronomy Yurij Baryshev 1, ∗ 1Astronomy Department, Mathematics & Mechanics Faculty, Saint Petersburg State University, 28 Universitetskiy Prospekt, 198504 St. Petersburg, Russia Modern multimessenger astronomy delivers unique opportunity for performing crucial ob- servations that allow for testing the physics of the gravitational interaction. These tests include detection of gravitational waves by advanced LIGO-Virgo antennas, Event Horizon Telescope observations of central relativistic compact objects (RCO) in active galactic nuclei (AGN), X-ray spectroscopic observations of Fe Kα line in AGN, Galactic X-ray sources mea- surement of masses and radiuses of neutron stars, quark stars, and other RCO. A very impor- tant task of observational cosmology is to perform large surveys of galactic distances indepen- dent on cosmological redshifts for testing the nature of the Hubble law and peculiar velocities. Forthcoming multimessenger astronomy, while using such facilities as advanced LIGO-Virgo, Event Horizon Telescope (EHT), ALMA, WALLABY, JWST, EUCLID, and THESEUS, can elucidate the relation between Einstein’s geometrical and Feynman’s quantum-field ap- proaches to gravity physics and deliver a new possibilities for unification of gravitation with other fundamental quantum physical interactions.

Overview of the SPEC Benchmarks
9 Overview of the SPEC Benchmarks Kaivalya M. Dixit IBM Corporation “The reputation of current benchmarketing claims regarding system performance is on par with the promises made by politicians during elections.” Standard Performance Evaluation Corporation (SPEC) was founded in October, 1988, by Apollo, Hewlett-Packard,MIPS Computer Systems and SUN Microsystems in cooperation with E. E. Times. SPEC is a nonprofit consortium of 22 major computer vendors whose common goals are “to provide the industry with a realistic yardstick to measure the performance of advanced computer systems” and to educate consumers about the performance of vendors’ products. SPEC creates, maintains, distributes, and endorses a standardized set of application-oriented programs to be used as benchmarks. 489 490 CHAPTER 9 Overview of the SPEC Benchmarks 9.1 Historical Perspective Traditional benchmarks have failed to characterize the system performance of modern computer systems. Some of those benchmarks measure component-level performance, and some of the measurements are routinely published as system performance. Historically, vendors have characterized the performances of their systems in a variety of confusing metrics. In part, the confusion is due to a lack of credible performance information, agreement, and leadership among competing vendors. Many vendors characterize system performance in millions of instructions per second (MIPS) and millions of floating-point operations per second (MFLOPS). All instructions, however, are not equal. Since CISC machine instructions usually accomplish a lot more than those of RISC machines, comparing the instructions of a CISC machine and a RISC machine is similar to comparing Latin and Greek. 9.1.1 Simple CPU Benchmarks Truth in benchmarking is an oxymoron because vendors use benchmarks for marketing purposes. -
Satyajit's Bhooter Raja
postScriptum: An Interdisciplinary Journal of Literary Studies Online – Open Access – Peer Reviewed ISSN: 2456-7507 postscriptum.co.in Volume II Number i (January 2017) Nag, Sourav K. “Decolonising the Eerie: ...” pp. 41-50 Decolonising the Eerie: Satyajit’s Bhooter Raja (the King of Ghosts) in Goopy Gyne Bagha Byne (1969) Sourav Kumar Nag Assistant Professor in English, Onda Thana Mahavidyalaya, Bankura The author is an assistant professor of English at Onda Thana Mahavidyalaya. He has published research articles in various national and international journals. His preferred literary areas include African literature, Literary Theory and Indian English Literature. At present, he is working on his PhD on Ngugi Wa Thiong’o. Abstract This paper is a critical investigation of the socio-political situation of the Indianised spectral king (Bhooter Raja) in Satyajit Ray’s Goopy Gyne Bagha Byne (1969) and also of Ray’s handling of the marginalised in the movie. The movie is read as an allegory of postcolonial struggle told from a regional perspective. Ray’s portrayal of the Bhooter Raja (The king of ghosts) is typically Indianised. He deliberately deviates from the colonial tradition of Gothic fiction and customised Upendrakishore’s tale as a postcolonial narrative. This paper focuses on Ray’s vision of regional postcolonialism. Keywords ghost, eerie, postcolonial, decolonisation, subaltern Nag, S. K. Decolonising the Eerie ... 42 I cannot help being nostalgic sitting on my desk to write on Satyajit Ray‟s adaptation of Goopy Gayne Bagha Bayne (1969). I remember how I gaped to watch the movie the first time on Doordarsan. Not being acquainted with Bhooter Raja (The king of ghosts) before, I got startled to see the shiny black shadow with flashing electric bulbs around and hearing his reverberated nasal chant of three blessings. -

Beyond the World of Apu: the Films of Satyajit Ray'
H-Asia Sengupta on Hood, 'Beyond the World of Apu: The Films of Satyajit Ray' Review published on Tuesday, March 24, 2009 John W. Hood. Beyond the World of Apu: The Films of Satyajit Ray. New Delhi: Orient Longman, 2008. xi + 476 pp. $36.95 (paper), ISBN 978-81-250-3510-7. Reviewed by Sakti Sengupta (Asian-American Film Theater) Published on H-Asia (March, 2009) Commissioned by Sumit Guha Indian Neo-realist cinema Satyajit Ray, one of the three Indian cultural icons besides the great sitar player Pandit Ravishankar and the Nobel laureate Rabindra Nath Tagore, is the father of the neorealist movement in Indian cinema. Much has already been written about him and his films. In the West, he is perhaps better known than the literary genius Tagore. The University of California at Santa Cruz and the American Film Institute have published (available on their Web sites) a list of books about him. Popular ones include Portrait of a Director: Satyajit Ray (1971) by Marie Seton and Satyajit Ray, the Inner Eye (1989) by Andrew Robinson. A majority of such writings (with the exception of the one by Chidananda Dasgupta who was not only a film critic but also an occasional filmmaker) are characterized by unequivocal adulation without much critical exploration of his oeuvre and have been written by journalists or scholars of literature or film. What is missing from this long list is a true appreciation of his works with great insights into cinematic questions like we find in Francois Truffaut's homage to Alfred Hitchcock (both cinematic giants) or in Andre Bazin's and Truffaut's bio-critical homage to Orson Welles. -

Son père, se réfugiant dans ses ambitions littéraires, laisse sa famille s’enfoncer dans la misère. Apu va alors découvrir le monde, avec ses deuils et ses fêtes, ses joies et ses drames. Sans jamais sombrer dans le désespoir, l’enfance du héros de la Trilogie d’Apu est racontée avec une simplicité émouvante. A la fois contemplatif et réaliste, ce film est un enchantement grâce à la sincérité des comédiens, la splendeur de la photo et la beauté de la musique de Ravi Shankar. Révélation du Festival de Cannes 1956, La Complainte du sentier (Pather Panchali) connut dès sa sortie un succès considérable. Prouvant qu’un autre cinéma, loin des grosses productions hindi, était possible en Inde, le film fit aussi découvrir au monde entier un auteur majeur et désormais incontournable : Satyajit Ray. -

Investigations of Various HPC Benchmarks to Determine Supercomputer Performance Efficiency and Balance
Investigations of Various HPC Benchmarks to Determine Supercomputer Performance Efficiency and Balance Wilson Lisan August 24, 2018 MSc in High Performance Computing The University of Edinburgh Year of Presentation: 2018 Abstract This dissertation project is based on participation in the Student Cluster Competition (SCC) at the International Supercomputing Conference (ISC) 2018 in Frankfurt, Germany as part of a four-member Team EPCC from The University of Edinburgh. There are two main projects which are the team-based project and a personal project. The team-based project focuses on the optimisations and tweaks of the HPL, HPCG, and HPCC benchmarks to meet the competition requirements. At the competition, Team EPCC suffered with hardware issues that shaped the cluster into an asymmetrical system with mixed hardware. Unthinkable and extreme methods were carried out to tune the performance and successfully drove the cluster back to its ideal performance. The personal project focuses on testing the SCC benchmarks to evaluate the performance efficiency and system balance at several HPC systems. HPCG fraction of peak over HPL ratio was used to determine the system performance efficiency from its peak and actual performance. It was analysed through HPCC benchmark that the fraction of peak ratio could determine the memory and network balance over the processor or GPU raw performance as well as the possibility of the memory or network bottleneck part.
