Vampir v4

Overview

Vampir allows visual modelling of the parallel performance of your code. Based on tracefiles generated by programs built against VampirTrace libraries it is possible to see where bottlenecks are occuring within the code. Vampir allows you to understand the application behaviour, analyse load balancing, learn about communication patterns and identify communication hotspots.

It does this by providing tools that show detailed timeline views of events and communication, statistical analysis of program execution, statistical analysis of communication operations, system snapshots and animations, and dynamic calling trees.

Restrictions on Use

We are licensed for Vampir on both newton and wren. However newer versions will not be made available for wren. Also tracefiles generated with previous versions of VampirTrace may not work with this newer version.
