Project description

The School of Electrical Engineering and Computer Science (EECS) invites applications for two doctoral student positions in Computer Science. The ScaLab (Scalable Parallel System Laboratory) is located in the main campus in Stockholm. ScaLab focuses on designing and optimizing algorithms, computer systems software, and architecture to improve the scalability of large-scale parallel computing systems, including high-performance computing and data centers. The doctoral students will work in a diversified research group with close interaction with other research groups in Sweden, Europe, and USA.
The doctoral students will work on the software ecosystem for converged high-performance computing and cloud computing systems. In particular, the system architecture will consist of multiple heterogeneous nodes equipped with multi-core processors, accelerators like GPUs, diverse memories like HBM and NVM, and disaggregated memory and storage. The doctoral students will have opportunities to research designing and developing open-source middleware solutions to be integrated into Kubernetes plugins, MPI, system software, and libraries, to improve the scalability and efficiency of large-scale applications in science, machine learning, and data analytics. The doctoral students will also have opportunities to develop advanced system-level characterization and optimization techniques for heterogeneous computing systems. The doctoral student will collaborate with multiple leading research teams within the project, build international collaboration, and develop research and project management skills. The research is carried out within the EU horizon projects OpenCUBE and IO-SEA.

Third-cycle subject: Computer Science

Supervision: Associate Professor Stefano Markidis and Assistant Professor Ivy Peng.
