In this paper, we propose an On-Demand Content Delivery Grid system that supplements the traditional content delivery network to deal with problems such as the huge influx of network traffic in a short period of time and the high cost in renting a fixed number of servers. We present its system architecture and describe its implementation in details. An experimental high-definition movie streaming site was setup using our content delivery grid system to demonstrate its capabilities with performance analysis.

An alternative to Quiescence: Tranquility

An alternative to Quiescence: Tranquility

International Conference on Software Maintenance (ICSM)

作者： Yves Vandewoude Peter Ebraert Yolande Berbers Theo D'Hondt Department of Computer Science Leuven Belgium Programming Technology Laboratory Brussels Belgium

This paper revisits a problem that was identified by Kramer and Magee: placing a system in a consistent state before and after runtime changes (1990). We show that their notion of quiescence as a necessary and sufficient condition for safe runtime changes is too strict and violates the black-box design principle. We introduce a weaker condition, tranquility; easier to obtain, less disruptive for the system and still sufficient to ensure application consistency. We also present an implementation of this concept in a component middleware platform

Simulating Structural Plasticity of the Brain more Scalable than Expected

arXiv 2022年

作者： Czappa, Fabian Geiß, Alexander Wolf, Felix Laboratory for Parallel Programming Department of Computer Science Technical University of Darmstadt Germany

Structural plasticity of the brain describes the creation of new and the deletion of old synapses over time. Rinke et al. (JPDC 2018) introduced a scalable algorithm that simulates structural plasticity for up to one billion neurons on current hardware using a variant of the Barnes–Hut algorithm. They demonstrate good scalability and prove a runtime complexity of O(n log2 n). In this comment paper, we show that with careful consideration of the algorithm and a rigorous proof, the theoretical runtime can even be classified as O(n log n). © 2022, CC BY-NC-ND.

A Machine Learning Based Plagiarism Detection in Source Code

A Machine Learning Based Plagiarism Detection in Source Code

引用

作者： Nickolay Viuginov Petr Grachev Andrey Filchenkov Faculty of Information Technologies and Programming International Laboratory "Computer Technologies" ITMO University

Converting source codes to feature vectors can be useful in programming-related tasks, such as plagiarism detection on ACM contests. We present a brand-new method for feature extraction from C++ files, which includes both features describing syntactic and lexical properties of an AST tree and features characterizing disassembly of source code. We propose a method for solving the plagiarism detection task as a classification problem. We prove the effectiveness of our feature set by testing on a dataset that contains50 ACM problems and ～90 k solutions for them. Trained xgboost model gets a relative binary f1-score=0.745 on the test set.

International Workshop on Active Middleware Services

作者： G. Kaiser J. Parekh P. Gross G. Valetto Department of Computer Science Programming Systems Laboratory Columbia University USA Telecom Italia Laboratory Italy

Autonomic computing - self-configuring, self-healing, self-optimizing applications, systems and networks - is widely believed to be a promising solution to ever-increasing system complexity and the spiraling costs of human system management as systems scale to global proportions. Most results to date, however, suggest ways to architect new software constructed from the ground up as autonomic systems, whereas in the real world organizations continue to use stovepipe legacy systems and/or build ''systems of systems'' that draw from a gamut of new and legacy components involving disparate technologies from numerous vendors. Our goal is to retrofit autonomic computing onto such systems, externally, without any need to understand or modify the code, and in many cases even when it is impossible to recompile. We present a meta-architecture implemented as active middleware infrastructure to explicitly add autonomic services via an attached feedback loop that provides continual monitoring and, as needed, reconfiguration and/or repair. Our lightweight design and separation of concerns enables easy adoption of individual components, as well as the full infrastructure, for use with a large variety of legacy, new systems, and systems of systems. We summarize several experiments spanning multiple domains.

Using Shared Arrays in Message-Driven Parallel Programs

Using Shared Arrays in Message-Driven Parallel Programs

IEEE International Symposium on Parallel and Distributed Processing Workshops and Phd Forum (IPDPSW)

作者： Phil Miller Aaron Becker Laxmikant Kale Parallel Programming Laboratory Department of Computer Science University of Illinois Urbana-Champaign USA

This paper describes a safe and efficient combination of the object-based message-driven execution and shared array parallel programming models. In particular, we demonstrate how this combination engenders the composition of loosely coupled parallel modules safely accessing a common shared array. That loose coupling enables both better flexibility in parallel execution and greater ease of implementing multi-physics simulations. As a case study, we describe how the parallelization of a new method for molecular dynamics simulation benefits from both of these advantages. We also describe a system of typed handle objects that embed some of the determinacy constraints of the Multiphase Shared Array programming model in the C++ type system, to catch some violations at compile time. The combined programming model communicates in terms of these handles as a natural means of detecting and preventing errors.

作者： J. Fagerstrom L. Stromberg Programming Environments Laboratory Department of Computer and Information Science Linköping University Sweden

A paradigm and system are presented that will support a programmer when designing, programming, and testing a distributed application. The main point is that the structure introduced by the paradigm must be keep and used during design, programming, and testing. A structural model that is based on common structures in distributed systems has been developed. This structural model is used to describe the logical relationships between components in a system, and is also integrated into a programming environment.< >

The author presents a paradigm and system that will support a programmer who is designing, programming, and testing a distributed application. The main point is that the structure introduced by the paradigm must be kept and used during design, programming, and testing. One is not helped by a programming method which introduces a structure just to break it down again. A structural model has been developed which is based on common structures in distributed systems. This model is used to describe the logical relationships between components in a system. It is also integrated into the programming environment.< >

CHIP in plain logic

CHIP in plain logic

IEEE Pacific Rim Conference on Communications, computers and Signal Processing

作者： M.R. Levy M.H. van Emden Logic Programming Laboratory Department of Computer Science University of Victoria Victoria BC Canada

The programming language Prolog allows succinct representation of a wide variety of scheduling problems. To speed up execution, a new version called CHIP (Constraint Handling In Prolog) was introduced that maintains the programming advantages of Prolog. CHIP achieves its speed by keeping track of the sets of possible values for each variable. In this way, a search can be abandoned as soon as any such set becomes empty. This mechanism is made part of the unification algorithm. CHIP maintains the conventional orientation of logic towards single values. Thus, an awkward theoretical structure results from interfacing with set orientation in unification. This problem is solved by using a set-orientation for the entire logic.< >

Explorative research is a vital part of biological sciences. Biologists frequently have to examine and compare multiple (large) sets of biological data in an interactive and explorative manner. Exploring alternative ways of examining the data and managing the necessary resources often require substantial (manual) effort and time. In this paper, we present a concrete example of how VLAM, a grid-based workflow management system, can enhance experimentation. We discuss in detail the process of developing the SigWin-detector, an application in the domain of bioinformatics. We show that SigWin-detector can promptly identify regions of increased gene expression in transcriptome maps and periodicity in weather data. We also show that the workflow can be extended or partially modified. The individual modules can also be used to compose different experiments. SigWin-detector fulfills the requirements of interactive and explorative experimentation. ©2006 IEEE.
