( Fall 2007 ) Lecture 12 : Reed - Solomon Codes

We begin with the definition of Reed-Solomon codes. Definition 1.1 (Reed-Solomon code). Let Fq be a finite field and Fq[x] denote the Fq-space of univariate polynomials where all the coefficients of x are from Fq. Pick {α1, α2, ...αn} distinct elements (also called evaluation points) of Fq and choose n and k such that k ≤ n ≤ q. We define an encoding function for Reed-Solomon code as RS : Fq → ...

Fall-12: Introducing the basics of user-level multithreading

Current parallel libraries and languages often rely on user-level threads to allow for massive concurrency. However, even junior or senior students often have difficulties with the understanding of the pros and cons of user-level threading, due to a lack of concrete experience with its implementation. In this poster, we describe our effort to introduce this concept in the introductory Computer ...

A spreading metric on the graph G for a given MLA problem instance is an assignment, δ : E → Q, of lengths to the edges of the graph that has the following properties: • The volume of a spreading metric, ∑ (i,j)∈E δi,jwi,j, of graph G in the MLA problem instance provides a lower bound on the value of the optimal solution of the MLA problem. • It “spreads apart” (w.r.t. metric lengths) the nontr...
