Effective resource sharing protocols will benefit industry

Dec 22, 2017 | Research/Cooperation

Technology in industry is developing all the time to be able to perform increasingly more tasks. To be able to manage this, computer systems steering the technology need to be more powerful. This is something that MDH researcher Sara Afshar has been taking a closer look at.


– My research is about developing faster and high efficient computer systems that will be able to perform a lot of tasks within a certain time interval. This type of system is used for example in applications that steer machines in industry, says Sara Afshar, doctoral student in Embedded Systems, at MDH. 

In her doctoral thesis, “Lock-Based Resource Sharing for Real-Time Multi-Processors”, the focus lies on the resource management of multiprocessor systems with time demands. A processor can be compared to the brain of a computer system, and it steers what tasks a system should perform. In each processor, one or more programmes are run, where each programme is responsible for performing a particular task in the system. A multiprocessor system consists of several processors which together create a more powerful system that can perform a lot of tasks. Such a system also means that the programmes share the system’s resources, such as memory for example. So that the resources are able to be shared in a secure and correct way, and that the system’s tasks are performed in time, a technique called a resource sharing protocol is used.

– But today’s resource sharing protocols aren’t powerful enough. Therefore my colleagues and I have produced new and more efficient types of protocol which considerably improve their performance, based on a time perspective, compared with what was previously possible. With such efficient resource management solutions, the amount of resources used in a system is reduced, which in turn means that industry can produce systems that are more powerful but cost less, says Sara Afshar.

On 19 December she defended her doctoral thesis in Computer Science and Engineering, at 13:30 in the Kappa Hall at MDH in Västerås.

– After the public defence of my thesis I would like to continue within a similar research domain, to solve the technical problems facing companies and industries, says Sara Afshar.
