Our goal in designing a new performance tool was to provide detailed, flexible performance information without incurring the space (and time) overhead typically associated with trace-based tools. Paradyn achieves this goal by dynamically instrumenting the application and automatically controlling this instrumentation in search of performance problems. Dynamic instrumentation lets us defer insertion until the moment it is needed (and remove it when it is no longer needed); Paradyn's Performance Consultant decides when and where to insert instrumentation VL - 28 SN - 0018-9162 CP - 11 M3 - 10.1109/2.471178 ER -
