23 pages           Performance Oriented Specification for 
                     Heterogenous Parallel Systems using 
		        Graphical Based Specifications
..
Today, multiprocessor systems can be used even for the solution of small 
problems. In contrast to this advantage in the development of hardware 
solutions there are only a few methods to specify and to generate 
efficient parallel programs especially in the area of heterogenous 
systems.
..
In the report we intend to show that Petri Nets are a suitable descrip-
tion language for doing so. An important point in this favour is that 
Petri Nets can  represent both aspects influencing the quality of a 
solution in an uniform model: the software and the hardware on which the 
generated program will be executed.  In that way the executable program 
can be derived by compiling the corresponding part of the model.   ...
