Emily Gibson Hill to Give Talk on Intuitive Program Comprehension Tools

Emily Gibson Hill from the University of Delaware will give a talk on applying natural-language analysis to understanding large software systems.

Developing Natural Language-based Software Analyses & Tools to Expedite Software Maintenance

Friday, December 4, 11:15 a.m.
Parmly 405
Pizza lunch to follow

Abstract:  Today’s software is large and complex, with systems consisting of millions of lines of code. New developers to a software project face significant challenges in locating code related to their maintenance tasks of fixing bugs or adding new features. Developers can simply be handed a bug and told to fix it–even when they have no idea where to begin.

We can significantly reduce the cost of software maintenance by reducing the time and effort to find and understand code. In this talk, I will outline the challenges in finding and understanding code in a large software project as well as present some software engineering tools that can help. Specifically, I will present techniques that leverage the textual information from comments and identifiers as well as program structure to create intuitive software engineering and program comprehension tools.

Bio: Emily Hill is a PhD candidate at the University of Delaware in Computer and Information Sciences. While an undergraduate at a liberal arts college, Emily researched information retrieval systems, which influenced her thesis topic. Her interdisciplinary thesis focuses on developing natural language processing and information retrieval techniques to improve software engineering tools. Emily spends much of her research time analyzing the natural language clues developers
leave behind in identifiers and comments. Outside of research, Emily enjoys singing opera, fantasy football, and reading.

 

Week of Dec 7 is National Computer Science Education Week

The U.S. House of Representatives passed a resolution to raise the profile of computer science as a transforming industry that drives technology innovation and bolsters economic productivity. The resolution, H. RES. 558, designates the week of December 7 as “National Computer Science Education Week” in honor of Grace Murray Hopper, one of the outstanding pioneers in the field of computer science, who was born on December 9, 1906.

Honor’s Thesis Abstract — Pasko Paskov

A Parallel Algorithm for Derivation of Regression Coefficients on the Graphics Processing Unit

Pasko Shterev Paskov

Regression analysis is one of the most common methods of statistical inference, finding its roots into scientific research from all areas for more than two centuries. It is used widely due to its intuitive way to establish a relationship between observations of different variables, and therefore provide empirical proof for a hypothetical connection, or dependence, between them.  Regression is an invaluable tool for both research and commerce alike, and has understandably received much attention from software companies in the past two decades, as they realized the immense potential of computers to improve and facilitate the use of the method. Although the contribution of such software to the use of regression should not be understated, the massive amounts of information that have become available with the rise of the digital age has made it increasingly more time consuming, and at instances near impossible, for machines to derive the estimated coefficients of regression. This is a very computationally intensive problem, and improving the efficiency of the algorithm is crucial to time-sensitive applications of regression. The series of graphics cards introduced in the past two years has found wide recognition as providing an accessible alternative to parallel computer clusters for many applications. The architecture and parallel capabilities of the GPU entail a great potential for an improvement of regression analysis calculations. This thesis introduces a new parallel regression algorithm in CUDA for use on the GPU, and demonstrates that this algorithm is between four times faster for smaller datasets and six hundred times faster for larger, depending also on the GPU architecture.

A Parallel Algorithm for Fast Edge Detection on the Graphics Processing Unit

Alexander Jackson

Often, it is a race against time to make a proper diagnosis of a disease. In areas of the world where qualified medical personnel are scarce, work is being done on the automated diagnosis of illnesses. Automated diagnosis involves several stages of image processing on lab samples in search of abnormalities that may indicate the presence of such things as tuberculosis. These imageprocessing tasks are good candidates for migration to parallelism which would significantly speed up the process. However, a traditional parallel computer is not a very accessible piece of hardware to many. The graphics processing unit (GPU) has evolved into a highly parallel component that recently has gained the ability to be utilized by developers for non-graphical computations.

This paper demonstrates the parallel computing power of the GPU in the area of medical image processing. We present a new algorithm for performing edge detection on images using NVIDIA’s CUDA programming model in order to program the GPU in C. We evaluated our algorithm on a number of sample images and compared it to two other implementations; one sequential and one parallel. This new algorithm produces impressive speedup in the edge detection process.
