NLAFET: Parallel Numerical Linear Algebra for Extreme Scale Systems


Today’s most powerful supercomputers are composed of hundreds of thousands of computing cores (CPUs and accelerators) connected in high speed networks that make up a massively parallel high performance computing (HPC) system. To effectively utilize this capacity, access to efficient and scalable parallel algorithms and software is necessary.

NLAFET is one of the high-profile extreme-scale computing research projects funded by the European Commission within the Future and Emerging Technologies (FET) program under Horizon 2020. The purpose of NLAFET is to tackle these challenges with the goal to minimizing the gap between the peak capabilities of the hardware and the performance realized by HPC applications. Achieving this requires a co-design effort including developing novel parallel algorithms, exploration of advanced scheduling strategies and runtime systems, offline and online autotuning, as well as avoiding communication and synchronization bottlenecks. In this presentation we give an overview of the project, discuss some of the challenges and how we are addressing them.
