We seek one (1) graduate student enrolled in a University MSc Program, to join our team contributing to the DEEP-SEA project. The candidate will participate in the R&D activities of FORTH in the context of the project DEEP-SEA: “DEEP – SOFTWARE FOR EXASCALE ARCHITECTURES”. The EuroHPC Research & Innovation project DEEP-SEA starts in April 2021 and will last for 3 years. It aims at improving software support for highly heterogeneous systems, which combine different processing units and diverse memory technologies. DEEP-SEA adopts the modular supercomputing architecture (MSA), and considers heterogeneity and performance at both the node level and at the system cluster level. Composability, programmability, portability, malleability, and reliability are targeted with a comprehensive system software and programming environment, which combines traditional models (MPI, OpenMP, OmpSs, GASPI) with higher-level, hardware-agnostic approaches (NabLab, DaCe).
