An Experimental Analysis for Memory Usage of GOS Core

Abstract

As grid software and grid applications grow in size and complexity, memory usage experiment and analysis have become more and more essential. In this paper, we investigate an antitestcase-based approach to analyze the memory usage of GOS core software, and present a set of anti-testcases, which describe predefined memory problems of GOS core. This approach is applied with a set of automated test tools in controlled experiments including basic memory requirements, memory errors and memory usage of GOS core. With the experiment and analysis, we find several memory usage results of GOS core and they are valuable for other systems based on JVM, Tomcat and Axis. We also give some JVM memory configuration suggestions for better performance in the production server.
