Institution Background

University of Tartu (UT), founded in 1632 is one of the oldest universities in Northern and Eastern Europe. UT Institute of Computer Science offers degrees on all levels of higher education. The Institute is a key research partner in the Estonian Center of Excellence in Computer Science and in the Software Technology and Applications Competence Centre – an R&D centre conducting industry-driven research projects involving industry partners.


Research Group Background

The Distributed Systems (DS) research group is covering the wide area of parallel and High Performance Computing (HPC) and distributed systems. The research group has vast experience in the fields of HPC, parallel algorithm design, very large problem solution methods, desktop computing environments, parallel software engineering, real-time analysis, and mobility predictions of big data originating from location-aware services like mobile networks. The group is performing quite a few challenging research projects. For example, automatic parallelisation of numerically intensive codes is a study to adapt methodology, languages and parallel application development strategies to the changing state of the art parallel and distributed computing environments. One such system has been developed in the research group: the Friend-to-friend (F2F) computing environment. The research group has been developing a parallel solvers for large sparse systems of linear equations as well as performing research on speeding up such calculations using GPU clusters and other networked performance boosting hardware components.

Mobile & Cloud Lab, which recently emerged from DS research group, conducts research and teaching in the mobile computing and cloud computing domains. The research topics include cloud computing, mobile application development, mobile cloud, mobile web services and migrating scientific computing and enterprise applications to the cloud.
