Triva - Three dimension-Interactive Visualization Analysis

Participants : Lucas Schnorr [ corespondant ] , Guillaume Huard.

Parallel applications use grid infrastructures to obtain more performance during their execution. The successful result of these executions depends directly on a performance analysis that takes into account the grid characteristics, such as the network topology and resources location. Triva is a software analysis tool that implements a novel technique to visualize the behavior of parallel applications. The proposed technique explores 3D graphics in order to show the application behavior together with a description of the resources, highlighting communication patterns, the network topology and a visual representation of a logical organization of the resources. We have used a real grid infrastructure in order to execute and trace applications composed of thousands of processes. http://triva.gforge.inria.fr under GNU GPL licence.
