  • Optimizing the Use of High Performance Software Libraries
    Optimizing the Use of High Performance Software Libraries Samuel Z. Guyer and Calvin Lin The University of Texas at Austin, Austin, TX 78712 Abstract. This paper describes how the use of software libraries, which is preva- lent in high performance computing, can benefit from compiler optimizations in much the same way that conventional computer languages do. We explain how the compilation of these informal languages differs from the compilation of more conventional computer languages. In particular, such compilation requires precise pointer analysis, requires domain-specific information about the library’s seman- tics, and requires a configurable compilation scheme. Finally, we show that the combination of dataflow analysis and pattern matching form a powerful tool for performing configurable optimizations. 1 Introduction High performance computing, and scientific computing in particular, relies heavily on software libraries. Libraries are attractive because they provide an easy mechanism for reusing code. Moreover, each library typically encapsulates a particular domain of ex- pertise, such as graphics or linear algebra, and the use of such libraries allows program- mers to think at a higher level of abstraction. In many ways, libraries are simply in- formal domain-specific languages whose only syntactic construct is the procedure call. This procedural interface is significant because it couches these informal languages in a familiar form, which is less imposing than a new computer language that introduces new syntax. Unfortunately, while libraries are not viewed as languages by users, they also are not viewed as languages by compilers. With a few exceptions, compilers treat each invocation of a library routine the same as any other procedure call.

  • SSC Reference Manual SDK 2017-1-17, Version 170
    SSC Reference Manual SDK 2017-1-17, Version 170 Aron Dobos and Paul Gilman January 13, 2017 The SSC (SAM Simulation Core) software library is the collection of simu- lation modules used by the National Renewable Energy Laboratory’s System Advisor Model (SAM). The SSC application programming interface (API) al- lows software developers to integrate SAM’s modules into web and desktop applications. The API includes mechanisms to set input variable values, run simulations, and retrieve values of output variables. The SSC modules are available in pre-compiled binary dynamic libraries minimum system library de- pendencies for Windows, OS X, and Linux operating systems. The native API language is ISO-standard C, and language wrappers are available for C#, Java, MATLAB, Python, and PHP. The API and model implementations are thread- safe and reentrant, allowing the software to be used in a parallel computing environment. This document describes the SSC software architecture, modules and data types, provides code samples, introduces SDKtool, and describes the language wrappers.

  • A Proposal for a Revision of ISO Modula-2 2
    A Proposal for a Revision of ISO Modula-2 Benjamin Kowarsch, Modula-2 Software Foundation ∗ May 2020 (arXiv.org preprint) Abstract The Modula-2 language was first specified in [Wir78] by N. Wirth at ETH Z¨urich in 1978 and then revised several times. The last revision [Wir88] was published in 1988. The resulting language reports included ambiguities and lacked a comprehensive standard library. To resolve the ambiguities and specify a comprehensive standard library an ISO/IEC working group was formed and commenced work in 1987. A base standard was then ratified and published as IS 10514-1 in 1996 [JTC96]. Several conforming compilers have since been developed. At least five remain available of which at least three are actively maintained and one has been open sourced. Meanwhile, various deficiencies of the standard have become apparent but since its publication, no revision and no maintenance has been carried out. This paper discusses some of the deficiencies of IS 10514-1 and proposes a limited revision that could be carried out with moderate effort. The scope of the paper has been deliberately limited to the core language of the base standard and therefore excludes the standard library. 1 ISO/IEC Standardisation [II20] describes ISO/IEC standardisation procedures, summarised in brief below. 1.1 Organisational Overview The International Organisation for Standardisation (ISO) and the International Electrotechnical Commission (IEC) operate a joint technical committee (JTC1) to develop, publish and maintain information technology standards. JTC1 is organised into subcommittees (SC) and working groups (WG). The subcommittee for programming languages is JTC1/SC22. The working group that developed the ISO Modula-2 standard was JTC1/SC22/WG13.

  • Finding What C++ Lost: Tracking Referent Objects with GCC
    MEng Project Report Finding What C++ Lost: Tracking Referent Objects with GCC Alexander Lamaison Department of Computing Imperial College London <[email protected]> Supervisor: Paul H. J. Kelly <[email protected]> 16th June 2007 ii Abstract Pointer arithmetic in C and C++, though powerful, is inherently dangerous and a constant source of program flaws. Technologies exist to reduce these risks, one of which is Mudflap: an extension to GCC 4 that performs runtime bounds-checking. This has an number of weak- nesses, notably its inability to detect the case of pointers that stray between objects allocated adjacently. We have created MIRO, an improved version which uses the stricter approach of referent object tracking. As well as increasing the effectiveness of the checking, this allows us to provide more useful debugging information when violations occur. It requires no changes to existing C and C++ programs including non-compliant, but common, calculations involving invalid pointer values. Code compiled with MIRO can be mixed freely with unchecked code combining safety with performance and reducing the threshold to adoption. Acknowledgements I would like to thank, firstly, my supervisor and mentor Paul Kelly for guiding me through this project as well as the last four years of study and for always listening to my ramblings without complaint. Steven Lovegrove, my friend, in particular for helping me track down the source of the C++ STL problem but for help with many other problems too. Also John Wilander, Mariam Kamkar, Michael Zhivich, Tim Leek and Richard Lippmann for kindly donating the source code to their testbeds that were so invaluable throughout this project.

  • CPSC 213: Assignment 7
    CPSC 213: Assignment 7 Due: Monday, March 12, 2012 at 6pm. Late assignments are accepted until Wednesday, March 14 at 6pm with a 25% penalty per day (or fraction of a day) past the due date. This rule is strictly applied and there are no exceptions. Goal In this assignment you will investigate interrupts and asynchronous programming by reading and modifying a program that uses signals to trigger asynchronous actions. This assignment is closely modeled on the asynchronous disk read example discussed in the lecture and gives you a chance to experience this sort of programming first hand, using a software environment that mimics hardware interrupts. Interrupts, Signals and Asynchronous Programming Included with this assignment is a small C program called async.c. This program uses a Unix OS feature called “signals” to mimic hardware interrupts. In the boot procedure, the program registers interruptServiceRoutine as a signal handler for the SIGALRM signal and then tells the OS to deliver this signal to the program once every second. The program includes a method called doAsync that schedules an asynchronous event, sort of like a disk-read request. These events complete in order, one at a time, each time the SIGALRM is delivered to the program. The doAsync procedure enqueues events on a circular completion queue and interruptServiceRoutine dequeues these completion events when SIGALRMs arrive and delivers the completion by calling the completion routine with two parameters, a pointer and an int, whose meaning is determined by the completion routine. You will note the use of the type void*. This type is called an “opaque pointer” and is used to store pointers of any type.
