Uniform Resource Visualization (urv): Software & Services

Computing environments continue to increase in scale, heterogeneity, and hierarchy, with resource usage varying dynamically during program execution. Computational and data grids and distributed collaboration environments are examples. To understand performance and gain insights into developing applications that efficiently use the system resources, performance visualization has proven useful. However, visualization tools often are specific to a particular resource or level in the system, possibly with fixed views, and thus limit a user’s ability to observe and improve performance. Information integration is necessary for system-level performance monitoring. Uniform resource visualization (URV) is a component-based framework being developed to provide uniform interfaces between resource instrumentation (called resource monitoring components, RMC) and performance views (called visualization components, VC). URV supports services for connecting VCs to RMCs, and creating multi-level views, as well as visual schema definitions for sharing and reusing visualization design knowledge.
