About
Teaching
I am involved in teaching the following courses:
- TDT4255 Computer Design
- TDT01 Architecture of Computing Systems
- DT8123 Advanced Computing
I also supervise project and master thesis topics within computer architecture and design. Current project and master thesis topics are available at IDIs web pages. I often co-supervise projects and masters with local and national industry partners such as ARM, Nordic Semiconductor and Silicon Labs (formerly Energy Micro).
The topics and reports of my supervised master theses can be found on NTNU Open.
Research
The main goal of my research is to contribute to designing faster and more energy-efficient computers. More specifically, I investigate how computer hardware can specialize to the current application – to improve efficiency – while retaining sufficient generality to be efficient across diverse applications – to enable reuse. I am affiliated with the NTNU's Computer Architecture Lab (CAL) and currently serve as the deputy head of the Computing research group.
I am currently involved in the following research projects:
- Project Manager and PI of the Balancing Compute and Memory Performance in Reconfigurable Accelerators with Analytical Modeling (BAMPAM) project. BAMPAM is a young research talents project funded by the Norwegian Research Council program IKTPLUSS.
- Scientific advisor in the Boosting Widening Digital Innovation Hubs (BOWI) Horizon 2020 project.
We recently completed the TULIPP Horizon 2020 project, see our recently published book for more details. A key contribution is the STHEM utilities which makes it possible to non-intrusively estabilsh the energy consumption of source code constructs such as procedures and loops [video]. To make full use of STHEM, you need the Lynsyn power measurement unit which can be bought from Sundance.
I currently supervise/mentor the following PhD students and post docs:
- Fatemeh Ghasemi (main supervisor)
- Björn Gottschall (main supervisor)
- Lukas Liedtke (main supervisor)
- Joseph Rogers (main supervisor)
- Truls Asheim (co-supervisor)
- Anders Gaustad (co-supervisor)
- Amund Bergsland Kvalsvik (co-supervisor)
- David Metz (co-supervisor)
