The position

Are you interested in doing Computer Science research and improving yourself in this area? A PhD position is available at the Department of Computer Science at UiT The Arctic University of Norway. The research topic of this PhD is Accurate and Scalable Simulation of Edge Systems.You will be part of the Cyber-Physical Systems group.

General information about the position.The position is for a period of four years. The nominal length of the PhD programme is three years. The fourth year is distributed as 25 % each year and will consist of teaching and other duties. The objective of the position is that you complete research training to the level of a doctoral degree. Admission to the PhD programme is a prerequisite for employment, and the programme period starts on commencement of the position.

The workplace is at UiT in Tromsø. You must be able to start in the position within a reasonable time after receiving the offer. Preferably Winter/spring 2026. 

The project 

Edge systems play an important role within the computing continuum. They are at the core of various applications including:
• Environmental (agriculture, climate changes, monitoring)
• Smart Cities (traffic, security and emergencies) 
• Industrial (logistics, smart grids) 
• Health Care

Edge systems are complex. They comprise numerous heterogeneous distributed nodes. These nodes are computing, storing, monitoring, actuating, etc. To couple with these use-cases, edge nodes are based on various computing hardware such as classical computers, single-board computers or micro-controllers. Edge systems network is also complex and unique. It must permit edge nodes to coordinate and exchange information locally and remotely with other systems (e.g., Cloud). To address use-case specific constraints, a wide range of communication technologies are used (e.g., LoRa, Wi-Fi, Nb-IoT etc). On top of that, edge systems are highly dynamic. Nodes can be mobile and prone to connection drops. In extreme cases, node failures are common.

Because of this complexity, being able to rigorously study edge systems and distributed systems in general is crucial. Multiple approaches are available to study distributed systems (e.g., analytical models, emulation prototyping etc). Simulation is a key approach to study distributed systems. It enables researchers to perform complex studies in an easy and flexible way compared to other approaches. Moreover, simulation can be used as a building block and can be part of Digital Twins, which is commonly associated with edge systems use-cases.

This PhD project focuses on proposing a simulation approach that leverages the distributed memory architecture to perform distributed simulations on heterogeneous clusters. Following this approach requires rigorous parallelization of code and extensive validation experiments. Ultimately, distributed simulation would allow to leverage the computational power of cluster nodes and run simulations at scale. These nodes could be monitored and bench-marked during simulation runs. Combining these measurements to the current model predictions could address the problems raised by state-of-the-art shared memory approaches.
 

Duties of the position:• To address these research challenges, you will start your PhD with an in-depth literature study of edge systems, distributed systems and simulation. 
• You will perform experimental studies of computer systems with the emphasis on the time and energy consumption predictions. From this background, you will be able to provide the requirements and anticipate the challenges raised by the problem statement. 
• You will pursue with the design and the evaluation of a first prototype. You will perform extensive experiments to identify potential weaknesses and strength of your solution. 
• You will investigate strategies to overcome these weaknesses and evaluate them through numerous experiments. 
• You will compare the predictions of current state of the art simulators with the solution that you propose. 
• During your PhD, you will document your research work and publish into Computer Science conferences
and journals. 
• You will have the opportunity to perform teaching assignments in various Computer Science
courses and collaborate with researchers in this area.
