Dr Zheng WangSenior Lecturer
Dr. Zheng Wang was appointed as a Lecturer in the School of Computing and Communications at Lancaster University in September, 2013. Before joining Lancaster, he was a Research Associate at the University of Edinburgh, following the completion of his PhD in 2011. Prior to that he was a research staff member in IBM Research.
Dr. Wang's research focus is in the areas of parallel compilers, runtime systems and the application of machine learning to tackle the challenging optimisation problems within these areas. My research interests include:
- Compiler-based parallelism mapping: how to map a parallel program to the underlying hardware to achieve the best (energy-efficient) performance.
- Code generation and optimisation for heterogeneous many-cores: I am interested in how can compilers generate efficient code for the emerging heterogeneous many-core systems, such as a CPU-GPGPU system.
- Auto-parallelising compilers: I am currently investigating the use of dynamic analysis together with machine learning to develop a new approach that gives scalable performance for many-cores.
- Runtime scheduling: how to schedule multiple concurrently running tasks in a multi-tasking environment to maximise the system-level performance (e.g. throughput or energy-efficiency).
- Research into energy efficient computing through system software including just-in-time compilers and operating systems
