scalasca  2.3.1
About: SCALASCA v2 (Scalable Performance Analysis of Large-Scale Applications) is an toolset to analyze the performance behavior of parallel applications and to identify opportunities for optimization. Note: Requires the instrumentation and measurement infrastructure Score-P and the CUBE4 GUI.

SCOUT Developer Documentation

This is the source code documentation for the parallel trace analysis component of the Scalasca toolset called SCOUT. It's task is to locate patterns of inefficient behavior in event traces of parallel applications and to quantify associated waiting times separately for every call path and process/thread. To achieve scalability, SCOUT performs this pattern search in parallel by replaying the recorded tarce information, exchanging required event data on-the-fly.

The entire functionality is encapsulated in the namespace scout.
