This paper describes a testing and benchmarking framework built to support the community of computer scientists. The framework provides features for defining benchmarks, uploading program code and executing test runs on the test infrastructure. For every test run, the framework measures the performance of the execution in terms of execution time, resource consumption and the quality of the data output...
The peer-to-peer (P2P) paradigm operates in an uncontrolled voluntary environment and, as the shared resources contributed by the general public have no legal obligation with respect to resource provisioning, an incentive based approach is needed to motivate and encourage participants to continue with the project and attract new volunteers. The Berkeley Open Infrastructure for Network Computing (BOINC),...
This paper analyses the performance of a decentralized and fault-tolerant software layer for Desktop Grid resources management. The grid middleware under concern is named PastryGrid. Its main design principle is to eliminate the need for a centralized server, therefore to remove the single point of failure and bottleneck of existing Desktop Grids. PastryGrid (based on Pastry) supports the execution...
This paper presents a tool, the performance model manager, which addresses the complexity of the construction and management of a set of functional performance models on a computing server in a grid environment. The operation of the tool and the features it implements to achieve this goal are described. Integration of functional performance models with a GridRPC middleware, using the tool's interfaces...
The XML coded information is notorious for its verbosity over the actual effective payload. The solution for reducing the verbosity and the performance cost of XML has been the use of the alternative encoding schemes, other than pure text. The processing of the XML using computing resources sparingly is even more important in embedded, and otherwise restricted environments, when the services of the...
Web services based specifications have emerged as the underlying architecture for core grid services and standards, such as WSRF. XML is inextricably inter-twined with Web services based specifications, and as a result the design and implementation of XML processing tools plays a significant role in grid applications. These applications use XML in a wide variety of ways, including workflow specifications,...
Benchmarks are a central force in engineering progress, providing the objective ability to quantify improvement and justify design decisions. In previous work, we brought together the concepts of benchmarks and autonomic computing, describing a vision of benchmarks that quantitatively evaluate a computing system along the four core autonomic dimensions of self-healing, self-configuration, self-optimization,...
