Non-intrusive and interactive profiling in parasight
Ziya Aral, Ilya Gertner · 1988
Debugging the performance of parallel applications is crucial for fully utilizing the potential of multiprocessor hardware. This paper describes profiling tools in Parasight, a programming environment that is geared towards non-intrusive performance analysis and high-level debugging. In Parasight, profilers execute as observer programs which run concurrently with the target program and monitor its behavior. This design grew out of our experience in debugging and monitoring the performance of real parallel programs.
