The reference manual: [html] [dvi] [ps] [pdf] The MPFR FAQ (common to all MPFR versions). The bugs listed below have been fixed (latest update: 2020-06-02). The patches are distributed under the same license as this version of MPFR , that is, the GNU Lesser General Public License (GNU Lesser GPL ), version�3 or later. The following instructions are for Linux and may be similar for other operating systems. You can apply the patches in several ways: Apply the cumulative patch (version on Gforge via https) on the 4.0.2 release or a partially patched version with the command from the source directory. The -N option allows the patch command to ignore patches already applied. The -Z option sets the modification time of the patched files from time stamps given in the patch file, thus avoiding the need of some development utilities (such as autoconf ); this may generate a Not setting time warning for the PATCHES file, but you can safely ignore it. Under Microsoft Windows, in addition to the above options, you may need the -- binary option (this depends whether the end-of-lines have been converted when you downloaded the patch file). Also note that the --dry-run option does not work if the cumulative patch has some file listed several times. Or apply the individual patches below. Or checkout the 4.0 branch from the Subversion repository, e.g. with the command In this case, as said on the Gforge page, you should read the README.dev file for details on how to build MPFR . Also note that the branch may contain additional minor fixes. With the first two ways, the PATCHES file is modified, so that one can know what patches have been applied, using the mpfr_get_patches function. Moreover a suffix is added to the version string, but note that for practical reasons, not all the files where the version appears are patched; thus one can also track applied patches with the MPFR_VERSION_STRING macro (header) and the mpfr_get_version function (library). However, if some patches are not applied or if patches are applied in a different order, then the patch command will fail to update some chunks, so that the suffix is not always reliable for patches.

  • A Compiler Front-End for the WOOL Parallelization Library
    A compiler front-end for the WOOL Parallelization library GEORGIOS VARISTEAS KTH Information and Communication Technology Master of Science Thesis Stockholm, Sweden 2010 TRITA-ICT-EX-2010:291 Royal Institute of Technology A compiler front-end for the WOOL Parallelization library Georgios Varisteas yorgos(@)kth.se 15 October, 2010 A master thesis project conducted at Examiner: Mats Brorsson Supervisor: Karl-Filip Faxén Abstract WOOL is a C parallelization library developed at SICS by Karl-Filip Faxén. It provides the tools for develop- ing fine grained independent task based parallel applications. This library is distinguished from other similar projects by being really fast and light; it manages to spawn and synchronize tasks in under 20 cycles. However, all software development frameworks which expose radically new functionality to a programming language, gain a lot by having a compiler to encapsulate and implement them. WOOL does not differ from this category. This project is about the development of a source-to-source compiler for the WOOL parallelization library, supporting an extension of the C language with new syntax that implements the WOOL API, transform- ing it and eventually outputting GNU C code. Additionally, this compiler is augmented with a wrapper script that performs compilation to machine code by using GCC. This script is configurable and fully automatic. The main advantage gained from this project is to satisfy the need for less overhead in software development with WOOL. The simplified syntax results in faster and more economical code writing while being less error- prone. Moreover, this compiler enables the future addition of many more features not applicable with the current state of WOOL as a library.

Our approach is to take a collection of these kernels, across inputs, platforms, and other compilers. For example, the disperse them across a collection of compute nodes (each with optimization flag -O3 does not hold equal meanings across a different architecture), have them compiled and run, and compilers. Also, some flags are exclusive to certain compilers; bring the results to a central SQL database for deeper analysis. Properly conducting these activities requires a careful selection in those cases, a user who is forced to use a different compiler (or design) of these kernels, input generation methods for them, does not know which substitute flags to use.

  • Effectiveness of Floating-Point Precision on the Numerical Approximation by Spectral Methods
    Mathematical and Computational Applications Article Effectiveness of Floating-Point Precision on the Numerical Approximation by Spectral Methods José A. O. Matos 1,2,† and Paulo B. Vasconcelos 1,2,∗,† 1 Center of Mathematics, University of Porto, R. Dr. Roberto Frias, 4200-464 Porto, Portugal; [email protected] 2 Faculty of Economics, University of Porto, R. Dr. Roberto Frias, 4200-464 Porto, Portugal * Correspondence: [email protected] † These authors contributed equally to this work. Abstract: With the fast advances in computational sciences, there is a need for more accurate compu- tations, especially in large-scale solutions of differential problems and long-term simulations. Amid the many numerical approaches to solving differential problems, including both local and global methods, spectral methods can offer greater accuracy. The downside is that spectral methods often require high-order polynomial approximations, which brings numerical instability issues to the prob- lem resolution. In particular, large condition numbers associated with the large operational matrices, prevent stable algorithms from working within machine precision. Software-based solutions that implement arbitrary precision arithmetic are available and should be explored to obtain higher accu- racy when needed, even with the higher computing time cost associated. In this work, experimental results on the computation of approximate solutions of differential problems via spectral methods are detailed with recourse to quadruple precision arithmetic. Variable precision arithmetic was used in Tau Toolbox, a mathematical software package to solve integro-differential problems via the spectral Tau method.

Typeset in LATEX Digital Gothenburg, Sweden 2019 iv Fast Fourier Transform using compiler auto-vectorization DUNDAR GOC¨ Department of Mathematical Sciences Chalmers University of Technology Abstract The purpose of this thesis is to develop a fast Fourier transformation algorithm written in C with the use of GCC (GNU Compiler Collection) auto-vectorization in the multiplicative group of integers modulo n, where n is a word sized odd integer. The specific Fourier transform algorithm employed is the cache-friendly version of the Truncated Fourier Transform. The algorithm was implemented by modifying an existing library for modular arithmetic written in C called zn poly. The majority of the thesis work consisted of changing the code in a way to make integration into FLINT possible. FLINT is a versatile library, written in C, aimed at fast arithmetic of different kinds. The results show that auto-vectorization is possible with a potential speedup factor of 3.

  • Implementation of C Library for Constructing Packrat Parser with Statically Allocated Memory
    Journal of Information Processing Vol.26 335–344 (Mar. 2018) [DOI: 10.2197/ipsjjip.26.335] Regular Paper Implementation of C Library for Constructing Packrat Parser with Statically Allocated Memory Yuta Sugimoto1,a) Atusi Maeda1 Received: July 23, 2017, Accepted: September 28, 2017 Abstract: Packrat parsing is a recursive descent parsing method with backtracking and memoization. Parsers based on this method require no separate lexical analyzers, and backtracking enables those parsers to handle a wide range of complex syntactic constructs. Memoization is used to prevent exponential growth of running time, resulting in linear time complexity at th cost of linear space consumption. In this study, we propose CPEG – a library that can be used to write parsers using Packrat parsing in C language. This library enables programmers to describe syntactic rules in an internal domain-specific language (DSL) which, unlike parser combinators, does not require runtime data structures to represent syntax. Syntax rules are just expressed by plain C macros. The runtime routine does not dynamically allocate memory regions for memoization. Instead, statically allocated arrays are used as memoization cache tables. Therefore, programmers can implement practical parsers with CPEG, which does not depend on any specific memory management features, requiring fixed-sized memory (except for input string). To enhance usability, a translator to CPEG from an external DSL is provided, as well as a tuning mechanism to control memoization parameters. Pars- ing time compared to other systems when parsing JavaScript Object Notation and Java source files are given. The experimental results indicate that the performance of CPEG is competitive with other libraries.
