Abstract
With complex codes moving to systems of increasing on-node parallelism using OpenMP, debugging these codes is becoming increasingly challenging. While debuggers can significantly aid programmers, existing ones support OpenMP at a low system-thread level, reducing their effectiveness. The previously published draft for a standard OpenMP debugging interface (OMPD) is supposed to enable the debuggers to raise their debugging abstraction to the conceptual levels of OpenMP by mediating the tools and OpenMP runtime library. In this paper, we present our experiences and the issues that we have found on implementing an OMPD library prototyp for a commonly used OpenMP runtime and a parallel debugger.
