Abstract :
Developers of message-passing codes on massively parallel systems have to contend with difficulties that data-parallel programmers do not face, not the least of which is debuggers that do not scale with the degree of parallelism. In this paper, we present new scalable interaction paradigms and their embodiment in a time- and space-efficient debugger with scalable performance. The debugger offers scalable expression, execution, and interpretation of all debugging operations, making it easier to debug and understand message-passing programs
