Performance Monitoring and Visualization of Grid Scientific Workflows in ASKALON
نویسندگان
چکیده
The execution of scientific workflows in Grids can imply complex interactions among various Grid applications and resources spanning multiple organizations. Failures and performance problems can easily occur during the execution. However, online monitoring and detecting failures and performance problems of scientific workflows in Grids is a nontrivial task. So far little effort has been spent on supporting performance monitoring and visualization of scientific workflows for the Grid. In this paper we present an online workflow performance monitoring and visualization tool for Grid scientific workflows that is capable to monitor the performance and to detect failures of Grid workflows. We also support sophisticated visualization of monitoring and performance result. Performance monitoring is conducted online and Grid infrastructure monitoring is integrated with workflow monitoring, thus fostering the chance to detect performance problems and being able to correlate performance metrics from different sources.

Towards Workflow Sharing and Reuse in the ASKALON Grid Environment
As more Grid workflow applications are built, workflow sharing and reuse becomes important, because (i) building a Grid workflow application from scratch is still a challenging task for domain scientists, and (ii) reusing of established and validated workflows not only reduces workflow authoring time but also improves the quality of workflows. In this paper, we present a Grid workflow sharing a...
متن کاملWorkflow Conversion and Processing in the ASKALON Grid Environment
We present a novel approach for intermediate representation and processing of scientific workflows, applied in ASKALON Grid environment. We present the techniques used by us to make the representation self-contained and dynamic. In particular, we explain the principles of workflow conversion and speculative workflow prediction implemented by us. In a series of experiments we show the performanc...
متن کاملASKALON: A Development and Grid Computing Environment for Scientific Workflows
Most existing Grid application development environments provide the application developer with a nontransparent Grid. Commonly, application developers are explicitly involved in tedious tasks such as selecting software components deployed on specific sites, mapping applications onto the Grid, or selecting appropriate computers for their applications. Moreover, many programming interfaces are ei...
متن کاملASKALON: a tool set for cluster and Grid computing
Performance engineering of parallel and distributed applications is a complex task that iterates through various phases, ranging from modeling and prediction, to performance measurement, experiment management, data collection, and bottleneck analysis. There is no evidence so far that all of these phases should/can be integrated in a single monolithic tool. Moreover, the emergence of computation...
متن کاملOnline Performance Monitoring and Analysis of Grid Scientific Workflows
While existing work concentrates on developing QoS models of business workflows and Web services, few tools have been developed to support the monitoring and performance analysis of scientific workflows in Grids. This paper describes a Grid service for performance monitoring and analysis of Grid scientific workflows. The service utilizes workflow graphs and various types of performance data inc...
