In order to enhance the performance of modern computers; the current development is towards placing multiple cores on one chip instead of inreasing the clock rates. To gain a speed-up from this architecture; software programs have to be partitioned into several independent parts. A common representation of these parts is called a task graph or data dependency graph. The authors of this article have developed a module for the OpenModelica Compiler (OMC); which creates; simplifies and schedules such task graphs. The tasks are created based on the BLT (block lower triangular)-structure; which is derived from the right hand side of the model equations. A noticeable speed-up for fluid models on modern six-core CPUs can be achieved.
