This book presents new results in the construction and methodology of tools to support the development of parallel programs. It focuses on tools for debugging and performance analysis. We can observe two major trends in recent years: on one hand, tool developers want to solve the problem of tool interoperability. This question is crucial for application developers as they want to apply different tools from different producers to their programs at the same time. An infrastructure that provides interoperability could allow us to see synergetic effects when using multiple tools, thus increasing...
