Paper Abstract

This paper describes a data visualization tool developed to support prototype development and testing of software standard interfaces in the open systems environment. The visualization capability is an extension of the Clemson Automated Testing System (CATS). CATS is a research facility which has proven valuable in exposing and addressing critical issues in emerging areas such as the IEEE POSIX real-time extensions. Preliminary investigations with CATS involving real-time interfaces and statistical reasoning about large scenarios of tests has motivated the need for a data visualization capability. Current approaches to testing open systems interfaces include very limited visualization aids, such as 2D bar charts to represent statistical information about the test results. The visualization tool developed in this work extends these capabilities by introducing realism and abstraction via raytracing and hierarchical data representations. These capabilities support a more meaningful analysis of system behavior in that a new, more descriptive set of questions is possible. Experimental results achieved with CATS and the visualization of system behavior with respect to deadlines for real-time systems are presented. Future applications for the data visualization tool in the open systems standards arena are proposed.
