CubeGUI

Cube, which is used as performance report explorer for Scalasca and Score-P, is a generic tool for displaying a multi-dimensional performance space consisting of the dimensions (i) performance metric, (ii) call path, and (iii) system resource.

What CubeGUI can do for you

The Cube Software Framework facilitates the collection, processing, and analysis of application performance profiling data from Score-P and Scalasca. With this framework, users have access to a comprehensive set of tools for measuring and understanding application performance.

Cube (CUBE Uniform Behavioral Encoding) is suitable for analyzing a wide variety of performance data for parallel programs including MPI and OpenMP applications.

Cube has been designed around a high-level data model of program behavior called the cube performance space. The Cube performance space consists of three dimensions: a metric dimension, a program dimension, and a system dimension.

The metric dimension contains a set of metrics, such as communication time or cache misses. The program dimension contains the program's call-tree, which includes all the call paths onto which metric values can be mapped. The system dimension contains the components executing in parallel, which can be processes or threads depending on the parallel programming model. Each point of the space can be mapped onto a number representing the actual measurement for metric while the control flow of process/thread was executing call path. This mapping is called the severity of the performance space.

The display component CubeGUI can load such a file and display the different dimensions of the performance space using three coupled tree browsers. The browsers are connected in such a way that you can view one dimension with respect to another dimension.

CubeGUI

If the Cube file contains topological information, the distribution of the performance metric across the topology can be examined using the topology view. Furthermore, the display is augmented with a source-code display that shows the position of a call site in the source code.
