VAMPIR

Abstract

The VAMPIR visualization tool analyzes the performance of message-passing programs. It displays post-mortem trace-files in a variety of graphical views. It provides flexible filter operations to reduce the amount of information to be displayed, as well as rapid zooming and forward/backward motion in time to allow to quickly focus on arbitrary time intervals. Thus, the user can easily identify performance bottlenecks at the appropriate level of detail. Information displayed includes message-passing, collective communication and application subroutine execution. The VAMPIRtrace MPI profiling library generates VAMPIR traces. It hooks into the MPI profiling interface which guarantees low tracing overhead. The effects of distributed clock drifts are corrected automatically. Tracing can be enabled/disabled during runtime.
