The X Window based visualization environment VAMPIR has been developed to support performance analysis of message-passing programs.

VAMPIR translates a given trace file into a variety of graphical views

	single time system snapshots: panels that show system activities at a particular point of time;
	animation: option to look at a sequence of system snapshots to investigate the dynamic behavior;
	statistics: the component that summarizes system behavior for the time under investigation;
	time-line system view: detailed view of system activities, which are visualized on a time axis.

Moreover, it provides flexible filter operations to reduce the amount of information displayed. The most interesting part of VAMPIR is the powerful zooming feature that allows to identify problems at any level of detail.

VAMPIR is based on the research tool PARvis, which was originally developed by Forschungszentrum Jülich. VAMPIR is available as PALLAS product.

VAMPIR supports MPI, PVM, and PARMACS. The current implementation is available for a variety of different hardware platforms (IBM RS/6000, Sun Sparc, DEC MIPS computers (Ultrix), DEC Alpha, HP, and Silicon Graphics).
The VAMPIR trace library is suitable for Fortran 77, Fortran 90, C and C++ programs.
