Background and activities
Teaching
I am involved in teaching the following courses:
- TDT4255 Computer Design
- TDT4295 Computer Design Project (course wiki)
- DT8105 Computer Architecture 2
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
My main research area is memory systems for Chip Multiprocessors (CMPs). CMPs are often referred to as multi-core architectures. In addition, I am interested in heterogeneous computer systems, energy efficiency, computer architecture simulation, compilers and system software.
I am currently involved in the following research projects:
- Work Package leader in the EU Horizon 2020 project Towards Ubiquitous Low-power Image Processing Platforms (TULIPP)
- Principal investigator in the EU Horizon 2020 project Run-time Exploitation of Application Dynamism for Energy-efficient Exascale computing (READEX)
- Project Manager and PI for the Energy efficient high Performance computing research InfrastruCture (EPIC) project
- Principal investigator for the Reducing Power Consumption in Microprocessors (RPCM) project with Trondheim SME MyWo AS
- Project manager for the Single-ISA Heterogeneous MAny-core Computer (SHMAC) project
- Vectorized PARSEC Benchmarks (ParVec)
I currently supervise/mentor the following PhD students and post docs:
- Nico Reissmann (main supervisor)
- Björn Gottschall (main supervisor)
- Dr. Asbjørn Djupdal (mentor)
- Benjamin Bjørnseth (co-supervisor)
- Even Låte (co-supervisor)
- Lahiru Rasnayake (co-supervisor)
- Mostafa Koraei (guest researcher)
I have supervised/metored the following PhD students and post docs:
- Main supervisor for Dr. Yaman Umuroglu (2012-2018), next employer Xilinx
- Co-supervisor for Dr. Yahya Yassin (2012-2018), next employer Mode Sensors
- Mentor for Dr. Ananya Muddukrishna (2016-2018), next employer ÅF
- Mentor for Dr. Mohammed Sourori (2015-2017), next employer Accenture
- Co-supervisor for Dr. Odd Rune Strømmen Lykkebø (2012-2017), next employer Nnaisense
- Mentor for Post doc. Dr. Juan Manuel Cebrian (2012-2014), next employer UPC/BSC
- Mentor for Post doc. Dr. Nikita Nikitin (2013-2014), next employer Mentor Graphics
