Associate Professor Oliver Sinnen


Oliver Sinnen is a Associate Professor in the Department of Electrical, Computer, and Software Engineering at University of Auckland, New Zealand, where he leads the Parallel and Reconfigurable Computing (PARC).

Oliver Sinnen graduated in Electrical and Computer Engineering at RWTH Aachen University, Germany. Subsequently, he moved to Portugal, where he received his PhD from Instituto Superior Técnico (IST), University of Lisbon, Portugal in 2003. He was visiting instructor/professor for several months at École Normale Supérieure (ENS), Lyon, France in 2008, 2012 and 2015.

Oliver's work in the Parallel and Reconfigurable Computing (PARC) lab focuses on three research lines: task scheduling for parallel systems, software engineering for parallel computing and reconfigurable computing with FPGAs.

In task scheduling he has worked on scheduling models, in particular on models that precisely consider communication, and on optimal scheduling approaches. He is the sole author of the monograph "Task Scheduling for Parallel Systems", Wiley 2007. Oliver was the PI of a Marsden fund on Optimal Task Scheduling on Parallel Systems.

His work on software engineering for parallel computing has produced various language extensions, tools and libraries for parallel programming with Java: Pyjama (OpenMP for Java), Parallel Task, Parallel Iterator, available as Open Source.

In reconfigurable computing, Oliver has worked on domain specific high level synthesis and the use of high level languages, in particular OpenCL for FGPAs. He is part of the mega-science project the Square Kilometer Array (SKA) for which he develops low-power, high-performance solutions of radio astronomy algorithms on FPGAs. In particular he is working on Pulsar Search  in the Central Signal Processor (CSP) package.  He is a founding member of the  NZ SKA Alliance. He is also member of Te Pūnaha Ātea -- Space Institute at the UoA.
