  • Behavioral Non-Portability in Scientific Numeric Computing
    Behavioral Non-portability in Scientific Numeric Computing B B Yijia Gu1( ), Thomas Wahl1, Mahsa Bayati2( ), and Miriam Leeser2 1 College of Computer and Information Science, Northeastern University, Boston, USA {guyijia,wahl}@ccs.neu.edu 2 Department of Electrical and Computer Engineering, Northeastern University, Boston, USA {mbayati,mel}@coe.neu.edu Abstract. The precise semantics of floating-point arithmetic programs depends on the execution platform, including the compiler and the tar- get hardware. Platform dependencies are particularly pronounced for arithmetic-intensive parallel numeric programs and infringe on the highly desirable goal of software portability (which is nonetheless promised by heterogeneous computing frameworks like OpenCL): the same program run on the same inputs on different platforms often produces different results. Serious doubts on the portability of numeric applications arise when these differences are behavioral, i.e. when they lead to changes in the control flow of a program. In this paper we present an algorithm that takes a numeric procedure and determines an input that may lead to different branching decisions depending on how the arithmetic in the procedure is compiled. We illustrate the algorithm on a diverse set of examples, characteristic of scientific numeric computing, where control flow divergence actually occurs across different execution platforms. 1 Introduction Many high performance computing applications make use of floating-point arith- metic. It is well known that floating-point expressions produce different results on different machines, due to lack of associativity, etc. Most practitioners assume that this affects only the last few bits of a computation, and can safely be ignored. In this paper, we present several examples where code run on different platforms on the same inputs can produce not just different results but different control flow.

  • Developing Portable Software
    DEVELOPING PORTABLE SOFTWARE James D. Mooney Lane Department of Computer Science and Electrical Engineering, West Virginia University, PO Box 6109, Morgantown, WV 26506 USA Abstract: Software portability is often cited as desirable, but rarely receives systematic attention in the software development process. With the growing diversity of computing platforms, it is increasingly likely that software of all types may need to migrate to a variety of environments and platforms over its lifetime. This tutorial is intended to show the reader how to design portability into software projects, and how to port software when required. Key words: software engineering; software portability 1. INTRODUCTION Most software developers agree that portability is a desirable attribute for their software projects. The useful life of an application, for example, is likely to be extended, and its user base increased, if it can be migrated to various platforms over its lifetime. In spite of the recognized importance of portability, there is little guidance for the systematic inclusion of portability considerations in the development process. There is a fairly large body of literature on aspects of portability. A comprehensive bibliography is provided by Deshpande (1997). However, most of this literature is based on anecdotes and case studies (e.g. Blackham (1988), Ross (1994)). A few seminal books and papers on portability appeared in the 1970s (e.g. Brown (1977), Poole (1975), Tanenbaum (1978)). Several books on software portability were published in the 1980s (Wallis (1982), Dahlstrand (1984), Henderson (1988), LeCarme (1989)). None of these publications provide a systematic, up-to-date presentation of portability techniques for present-day software.

  • Investigating Software Maintainability Development: a Case for ISO 9126
    IJCSI International Journal of Computer Science Issues, Vol. 11, Issue 2, No 2, March 2014 ISSN (Print): 1694-0814 | ISSN (Online): 1694-0784 www.IJCSI.org 18 InInvestigatingvestigating Software Maintainability Development: A case for ISO 9126 Ahmad Haboush, Mohammad Alnabhan, Anas AL-Badareen, Mohammad Al-nawayseh and Bassam EL-Zaghmouri Faculty of Information Technology, Jerash University Jerash, Jordan Abstract Software maintainability has been considered as a main characteristic in many software product quality models. However, these models have different definitions for maintainability and sub characteristics. ISO 9126 is one of the main and most frequently used models in software product quality. This model has been revised and replaced by ISO 25010 as a new model of software product quality. In addition to the many modifications that were performed on ISO 9126 model, maintainability was one of the main modified characteristics. However, it was developed unclearly without any standard base, and with no clear definition or evidence of how the sub characteristics were defined and modified. This paper investigates these modifications and the differences between the definitions of the maintainability in the two models, ISO 9126 and ISO 25010. As a result of this discussion, it has been concluded that both models ISO 9126 and ISO 25010 lack of a clear definition or standard base for defining software maintainability and its sub characteristics.

Unfortunately, it is often neglected from the software development cycle, and rather achieved by ad hoc methods in not very cost-effective ways. This thesis investigates portability in the context of mobile development. Previous research in this particular area has been hard to find, despite there obviously being special aspects surrounding it which are worth investigating further. The project was initiated with a literature study to find out the current state-of-the-art for portability. After this step the development of a mobile application was conducted, before which a market analysis had been carried out in order to explore which mobile platforms would be the most relevant to develop it for.

It consists of translat- ing code running on a specific platform, to run on a different one and adapt with the new hardware. This thesis aims to present code porting and find possible guidelines to be applied when being per- formed, and contributes at the same time to the state of the art of code porting in embedded systems. Also, test these selected guidelines in a case study to validate whether they can be applied for each action of code porting. The case study consists of an autonomous underwater vehicle having a proportional integral deivative (PID) that is ported into a new hardware according to the selected guidelines. 1 M¨alardalenUniversity Master Thesis Table of Contents 1 Introduction 3 1.1 Problem Formulation...................................3 1.2 Research Questions....................................3 1.3 Thesis Contribution...................................4 1.4 Thesis Outline......................................4 2 Research Method5 3 Related Work 6 3.1 Code porting.......................................6 3.2 AUVs and PIDs.....................................8 4 Case Study Design and Planning 10 5 Implementation 13 5.1 Header Files.......................................
