Scalable Performance Analysis of Large-Scale Applications
Analysis report examination

The results of the runtime summarization and/or the automatic trace analysis are stored in one or more reports (i.e., CUBE4 files) in the measurement experiment directory. These reports can be post-processed and examined using the scalasca -examine (or short square) command, providing an experiment directory name as argument:

  $ scalasca -examine [options] <experiment_name>

Post-processing is performed leveraging commands provided by the CubeLib component the first time an experiment is examined, before launching the Cube analysis report browser (CubeGUI). If the scalasca -examine command is provided with an already processed experiment directory, or with a CUBE4 file specified as argument, the viewer is launched immediately.

Instead of interactively examining the measurement analysis results, a textual score report can also be obtained using the -s option (see Section square – Scalasca analysis report explorer for further command-line options) without launching the viewer:

  $ scalasca -examine -s <experiment_name>

This score report is generated by Score-P's scorep-score utility and provides a breakdown of the different types of regions included in the measurement and their estimated associated trace buffer capacity requirements, aggregate trace size, and largest process trace buffer size, which can be used to set up a filtering file and to determine an appropriate setting for SCOREP_TOTAL_MEMORY to be used for subsequent trace measurements. See Section Optimizing the measurement configuration for more details.

The Cube viewer can also be directly used on an experiment archive—opening a dialog window to choose one of the contained CUBE4 files—or an individual CUBE4 file as shown below:

  $ cube <experiment_name>
  $ cube <file>.cubex

However, keep in mind that no post-processing is performed in this case, so that only a subset of Scalasca's analyses and metrics may be shown.
