Patrick Bellasi



Patrick Bellasi is a Senior Software Engineer at ARM Ltd (Cambridge) working as a Linux scheduler specialist on Energy Aware Scheduling for ARM big.LITTLE technology.

He developed the EAS ‘SchedTune’ extension to provide per-task energy-vs-performance tuning which has been merged into the Android Common Kernel. He is also responsible for configurable tooling (LISA, BART, TRAPpy) used to analyse scheduler behaviour in product applications.

Previously, Patrick has been a Post-Doc at Politecnico di Milano, working in cooperation with STMicroelectronics in different projects related to SoCs energy optimization and run-time resource management of experimental many-core architectures.
