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 the programmer's productivity during implementation and testing. parallel program development. While this tool automation is not a new area, there remains much to be done. Parallel program development remains the domain of the expert and aficionado. This area continues to be an important one for the programmers and users of high performance computing.
