Large drilling machine control code — Parallelisation and WCET speedup

Abstract

Hard real-time applications in safety-critical domains — namely avionics, automotive, and machinery — require high-performance and timing analysability. We present research results of the parallelisation and WCET analysis of an industrial hard real-time application, i.e. the control code of a large drilling machine from BAUER Maschinen GmbH. We reached a quad-core speedup of 2.62 for the maximum observed execution time (MOET) and 1.93 on the WCET compared to the sequential version. For the WCET analysis we used the measurement-based WCET analysis tool RapiTime.
