Towards a parallel debugging framework for the massively multi-threaded, step-synchronous REPLICA architecture

Abstract

Modern chip-multiprocessors pack an increasing amount of computational cores with each generation. Along with new computational power comes a problem of managing a large pool of active threads. Traditional debuggers often deal with concurrency style multi-threading with emphasis on a single thread. The problem of thread management when debugging parallel programs is analyzed and solutions are suggested. A related debugging framework for the massively multi-threaded, synchronous REPLICA architecture is proposed.
