It describes computers with multiple processing elements that perform the same operation on multiple data simultaneously. Thus, such machines exploit data level parallelism. History The first use of SIMD instructions was in vector supercomputers of the early 1970s such as the CDC Star-100 and the Texas Instruments ASC, which could operate on a vector of data with a single instruction. Vector processing was especially popularized by Cray in the 1970s and 1980s. Vector-processing architectures are now considered separate from SIMD machines, based on the fact that vector machines processed the vectors one word at a time through pipelined processors (though still based on a single instruction), whereas modern SIMD machines process all elements of the vector simultaneously.[1] The first era of modern SIMD machines was characterized by massively parallel processing-style supercomputers such as the Thinking Machines CM-1 and CM-2. These machines had many limited-functionality processors that would work in parallel.

  • GIMPS Project Discovers Largest Known Prime Number : 277,232,917-1
    GIMPS Project Discovers Largest Known Prime Number : 277,232,917-1 The Great Internet Mersenne Prime Search (GIMPS) has discovered the largest known prime number, 277,232,917-1, having 23,249,425 digits. A computer volunteered by Jonathan Pace made the find on December 26, 2017. Jonathan is one of thousands of volunteers using free GIMPS software available at www.mersenne.org. The new prime number, also known as M77232917, is calculated by multiplying together 77,232,917 twos, and then subtracting one. It is nearly one million digits larger than the previous record prime number, in a special class of extremely rare prime numbers known as Mersenne primes. It is only the 50th known Mersenne prime ever discovered, each increasingly difficult to find. Mersenne primes were named for the French monk Marin Mersenne, who studied these numbers more than 350 years ago. GIMPS, founded in 1996, has discovered the last 16 Mersenne primes. Volunteers download a free program to search for these primes, with a cash award offered to anyone lucky enough to find a new prime. Prof. Chris Caldwell maintains an authoritative web site on the largest known primes, and has an excellent history of Mersenne primes. The primality proof took six days of non-stop computing on a PC with an Intel i5-6600 CPU. To prove there were no errors in the prime discovery process, the new prime was independently verified using four different programs on four different hardware configurations. • Aaron Blosser verified it using Prime95 on an Intel Xeon server in 37 hours. • David Stanfill verified it using gpuOwL on an AMD RX Vega 64 GPU in 34 hours.

  • C 2013 Alexander Jih-Hing Yee a FASTER FFT in the MID-WEST
    c 2013 Alexander Jih-Hing Yee A FASTER FFT IN THE MID-WEST BY ALEXANDER JIH-HING YEE THESIS Submitted in partial fulfillment of the requirements for the degree of Master of Science in Computer Science in the Graduate College of the University of Illinois at Urbana-Champaign, 2013 Urbana, Illinois Adviser: Professor Marc Snir ABSTRACT FFT implementations today generally fall into two categories: Library gen- erators (such as FFTW and Spiral) and specialized FFTs (such as prime95). Specialized FFTs have the obvious limitation of being specialized. However they are hand-tuned and generally offer superior performance. Library gen- erators are generic and easier to port. But their performance is generally suboptimal. We describe in this paper an FFT library that was built while paying special attention to locality. The library achieves significantly better perfor- mance than FFTW, for long vectors. Unlike FFTW or Spiral, the recursive decomposition of the FFT is not created by a library generator; it is created by macro expansion that has a few selectable parameters. This provides an interface that can be more easily modified by users. ii To my parents, for their love and support. iii TABLE OF CONTENTS LIST OF TABLES . v LIST OF FIGURES . vi LIST OF ABBREVIATIONS . vii CHAPTER 1 INTRODUCTION . 1 CHAPTER 2 FFT LIBRARIES . 3 2.1 Library Generators . 3 2.2 Specialized FFTs . 6 CHAPTER 3 OUR IMPLEMENTATION . 9 3.1 Generalized Bailey's 4-step Algorithm . 9 3.2 Blocking/Data Padding . 12 3.3 Fast Bit-Reversal . 15 3.4 Vector Instructions . 16 3.5 Micro-Optimizations: Loop Unrolling .

Create a bootable USB flash drive using the Media Creation Tool from Microsoft. This will also wipe any data stored on the USB flash drive. It is best to disconnect all storage disks except from the main (C Drive) disk “from the computer before installing Windows 10. 2. Boot into your USB that has the Windows 10 Media on it. You can do this by entering your systems' BIOS and change the BIOS boot order to have USB media as the first priority (this can usually be found under the boot tab), or simply look for the words "boot menu" when you see your BIOS boot screen, press the corresponding function key and choose the USB flash drive to boot from it. 3. Follow the steps on screen to install Windows 10. 4. Click Install now 5. Continue on until you hit the license key screen. Here you can either enter your license code or, if Windows has been installed to this computer before, click on the "I don't have a product key" link. 6. Continue on until you hit the “Which type of installation do you want?” screen. Click "Custom". 7. Click on each partition of the target drive and select delete.
