Experiences and Results of Parallelisation of Industrial Hard Real-time Applications for the parMERASA Multi-core
Résumé
The EC FP-7 project parMERASA (Multi-Core Execution of Parallelised Hard Real-Time Applications Supporting Analysability, Oct. 1, 2011 until Sept. 30, 2014) provides a timing analysable system of parallel hard real-time applications running on a scalable multi-core processor. parMERASA goes one step beyond mixed criticality demands: It targets future complex control algorithms by parallelising hard real-time programs to run on predictable multi-/many-core processors. A software engineering approach was developed to ease sequential to parallel program transformation by developing and supporting suitable parallel design patterns that are analysable. The following sequential hard real-time programs were parallelised by applying the pattern-oriented parallelisation approach: 3D path planning and stereo navigation algorithms (Honeywell International s.r.o.), diesel engine management system (DENSO AUTOMOTIVE Deutschland GmbH), and the control algorithm for a dynamic compaction machine (BAUER Maschinen GmbH). The paper reports on parallelisation approach, experiences made during parallelisation with applications, tools and multi-core architecture, scalability of applications and quantitative results reached.
