Graphics.c, a simplified graphics application programming interface for the X Window environment
No full textAn often overlooked area of graphics is the ability of application programs to create graphical images. Many programs exist which allow creation interactively, but few offer the same ability for noninteractive application programs. By allowing an application program to create graphical images more user friendly programs may be created by programmers.Thesis (M.S.)Department of Computer Scienc
Performance Evaluation Of The Parallel Fast Multipole Algorithm Using The Optimal Effectiveness Metric
No full textScalability measurements of parallel applications are of significant interest to the evaluation and characterization of various parallel algorithms, particularly in scientific computing. Previously, several metrics have been proposed and accepted by the community of researchers in parallel algorithm development. However, none of these have all the attributes required by an effective metric for parallel algorithm analysis. Recently, a new performance metric has been introduced: the optimal effectiveness (\Gamma opt ). It exhibits both qualitative and quantitative characteristics. This paper presents the performance evaluation of N-body simulations using the parallelized Fast Multipole Algorithm and two competing versions that include load balancing techniques. Using \Gamma opt , this paper reveals the inherent limitations of existing performance metrics and shows the advantages of employing the cost effectiveness metric for parallel applications. 1. INTRODUCTION Scalability measuremen..
Integrating Efficient Partitioning Techniques For Graph Oriented Applications
No full text. Load balancing and graph partitioning are areas of current research. Fractiling, a dynamic scheduling algorithm which balances loads by handling both predictable and unpredictable events, has been proven to improve application performance for N-body simulations. It operates by repeatedly subdividing the work into decreasing size chunks. For graph oriented applications, this means that a given graph would have to be partitioned many times throughout the execution of the application. Therefore to operate efficiently, when incorporated into graph oriented applications, Fractiling would require a highly efficient graph partitioning algorithm. This paper presents some of the current ongoing research being conducted by the NSF Engineering Research Center for Computational Field Simulation at Mississippi State University. This research seeks to improve the performance of graph oriented Computational Fluid Dynamic (CFD) applications by the integration of Fractiling and a highly efficient gr..

The group was a gathering of students--mostly women--interested in poetry, who met at the home of English Professor Victor L. O. Chittick [1921-1948] and also later at the home of Professor Lloyd Reynolds [1929-1969], who taught creative writing when first at Reed. The students would read their poetry and prose pieces to the group and sometimes discuss the work of published poets. The name came from Chittick's reference to the complete silence, the "Godawful Silence", that would meet his invitation to criticize. Members of the group included poet and Sappho translator Mary Barnard, author and poet Claudia Lewis, Dorothy Gill Wikelund, siblings Cecilia and Joe Gunterman, author Carolyn Bilderback, and many others

Fault-Tolerant System for Balancing the Load of Data-Parallel Applications
No full textIn distributed computing environments, fault--tolerance is an important objective, especially for parallel applications. Many distributed computing environments achieve fault--tolerance by periodic checkpointing. This has the advantage of relative ease of implementation and can be considered equivalent to task migration. However, there are two main disadvantages of such environments. One is that any work in progress after checkpoint- ing is lost when a fault occurs. The other is that these systems are heavily reliant on task migra- tion as the only mechanism for load balancing. This paper presents a system that overcomes these shortcomings by task duplication and by the integration of data migration into task migration as a load balancing mechanism. It also presents results of a preliminary implementation. Key Words: Distributed computing, Task Migration, Load Balancing, Fault--Tolerance Point of Contact: Samuel H.
