Treffer: G.: Pajé trace file format

Pajé is an interactive and scalable trace-based visualization tool which can be used for a large variety of visualizations including performance monitoring of parallel applications, monitoring the execution of pro-cessors in a large scale PC cluster or representing the behavior of distributed applications. Users of Pajé can tailor the visualization to their needs, without having to know any insight nor to modify any component of Pajé. This can be done by defining the type hierarchy of objects to be visualized as well as how these objects should be visualized. This feature allows the use of Pajé for a wide variety of visualizations such as the use of resources by applications in a large-size cluster or the behavior of distributed Java applications. This report describes the trace format used by Pajé. Traces include three different kind of informations: definition of the formats of the event, definition of the type hierarchy of the objects to be visualized, definition of the formats of the events of the trace and a set of recorded events, complying with the format definition, to be
