In this video from ISC 2019, Thomas Lippert from the Jülich Supercomputing Centre describes how the modularity approach is paving the way forward for HPC in Europe.
After that, Bernhard Frohwitter and Hugo Falter from ParTec discuss how the company supports modular supercomputing for enhanced user productivity.
"Looking at the challenges future supercomputing architectures have to overcome, the question arises if the leap to Exascale computing can only be achieved by special-purpose next-gen systems with diverging properties. The novel concepts the DEEP and DEEP-ER projects put forward challenge this idea and contrast it with a modular approach to future supercomputers: The system features different types of processors that facilitate different concurrency levels. It also employs a fine-grained memory hierarchy with new technologies like non-volatile and network attached memory and a massively parallel file system to just mention a few building blocks. All these components can be seen as pool of resources HPC application scientists can choose from. Designing this sophisticated architecture was only possible through a continuous co-design effort and vivid exchange between hardware, system software, and application developers. All in all, this novel architecture allows for diverging properties within a single system and its modular concept could also allow for integrating completely new technologies like bio or quantum computing once available."
