IVD: An Integrated Performance Visualization and Debugging Tool for Parallel Applications

Karp, Alan H.; Hao, Ming C.; Singh, Vineet; Mackey, Milon; Chien, Jane



Abstract: IVD is a tool that simplifies the task of debugging parallel programs. Key features include the ability to group tasks into sets and perform standard debugging operations (e.g., single-step) simultaneously on any of these subsets. IVD integrates performance and data visualization, including the ability to visualize distributed arrays. Since IVD is independent of the visualizers and debuggers, programmers may use their favorite tools.
