The dynamic probe class library-an infrastructure for developing instrumentation for performance tools

The complexity of both parallel architectures and parallel applications poses several problems for the development of performance analysis and optimization tools. In this paper, we describe the motivations and the main aspects of the design of the Dynamic Probe Class Library (DPCL), an object based C++ class library that provides an infrastructure to reduce the cost of writing instrumentation for performance tools. Additionally, we present some of the performance tools built on top of DPCL, which demonstrate the power and flexibility of the library.
