It is based on the assumption that a higher acceleration can be achieved in an easier way, if the problem is alread tackled early at the modeling stage [STOP 95]. The user adds hints about the communication behavior and frequencies of object classes to the simulation model. Based on this information, an object graph is generated and distributed to a selected number of partitions. The distribution phase is fully automatic. As a result a distribution of the problem nearby the communication optimum is generated. In the next phase the distributed simulation program (code) is generated. In a final step the user only has to code the methods of the object classes and run the simulation. The major advantage of this approach is that the user is freed from the difficult task of finding a good distribution for the problem to be simulated, which is an important factor for the overall performance of the simulation. Another advantage is the possibility to vary model information (hints) about the communication, and get a new (quasi optimal) version of the simulation automatically generated.}, issn = {1-565-55099-4}, language = {EN}, pdf = {https://www.itec.aau.at/bib/files/1996-0020-StBo.pdf}, talktype = {none} }
