Scalable yet rigorous floating-point error analysis | Proceedings of the International Conference for High Performance Computing, Networking, Storage and Analysis 这篇工作讨论如何分析-统计 浮点数计算相对于真实计算的误差,主要关心一些复杂数学计算的实现(数值分析)。 这似乎还不是一个足够成熟的领域,比如不能...
Robust parallel computation in floating-point and SLI arithmetic In this paper we consider the parallel computation of vector norms and inner products in floating-point and a proposed new form of computer arithmetic, the... DW Lozier,PR Turner - 《Computing》 被引量: 13发表: 1992年 加载更多0...
In the first the bounds are derived for the rounding errors made in the fundamental floating-point arithmetic operations. In the second, these results are applied in the analysis of a number of computing techniques for the calculation of the eigenvalues of matrices. In each case thecomputed ...

Floating-Point Exception Error: Exploring the Causes and Solutions Introduction: In the world of computing, errors or exceptions are inevitable. One such error that programmers and users frequently encounter isthe "floating-point exception error." Often denoted as FPE, this error occurs when a progr...
A floating-point is a way of representing and performing arithmetic operations on real numbers in computing. It's a numerical data type that allows you to handle values with fractional parts and a wide range of magnitudes. The term "floating-point" refers to the fact that the decimal point ...
PARDISO produces a floating-point error in phase 22, if the coefficient matrix of a FEM analysis has zero pivots. Another problem is, that PARDISO doesn’t return the correct line number of the first pivot element (iparm[29]). In former versions PARDISO worked well in this regard...
Using a floating-point format with parameters and p, and computing differences using p digits, the relative error of the result can be as large as - 1. Proof A relative error of - 1 in the expression x - y occurs when x = 1.00...0 and y = ..., where = - 1. Here y has p...
point numbers on the error of accumulative sum in the process of single precision floating-point accumulation through experimental methods,and aimed to explore the law of caused calculation errors by the binding sequence,provided a basis for a method of selective binding for computing paradigm and ...
