摘要: The expert tool environment provides a complete tracing-based solution for automatic performance analysis of mpi, Openmp, or hybrid applications running on smp cluster machines. describes problems using high level abstraction in terms common situations that result from an inefficient use the underlying programming model(s). set supported is extensible and can be custom tailored to application-specific needs. carried out along three interconnected dimensions: class behavior, call tree position, thread execution. Each dimension arranged hierarchy, so user view behavior varying levels detail. All dimensions are interactively accessible scalable but still accurate display. Colors provide assistance finding interesting nodes even case large trees.
