中文简介:
低点计算是高能物理学中大部分计算的核心。这些计算的正确性,速度和准确性至关重要。缺乏任何这些特征可能意味着新的,令人兴奋的物理学和令人尴尬的校正之间的差异。本讲座将研究在HEP应用中遇到的IEEE 754 2008浮点运算的实际方面。在描述了IEEE浮点运算的基本特征之后,演示将涵盖:通用硬件实现(SSE,x87)技术,用于提高求和,乘法和数据交换的精度,gcc和icc的编译器选项可以避免影响浮点运算危险
课程简介: loating-point computations are at the heart of much of the computing done in high energy physics. The correctness, speed and accuracy of these computations are of paramount importance. The lack of any of these characteristics can mean the difference between new, exciting physics and an embarrassing correction. This talk will examine practical aspects of IEEE 754-2008 floating-point arithmetic as encountered in HEP applications. After describing the basic features of IEEE floating-point arithmetic, the presentation will cover: common hardware implementations (SSE, x87) techniques for improving the accuracy of summation, multiplication and data interchange compiler options for gcc and icc affecting floating-point operations hazards to be avoided
关 键 词: 低点计算; 高能物理学; HEP应用; IEEE 754 2008浮点运算
