based on a dynamic, modular su- percomputing which


architecture, Forschungszentrum


Jülich developed together with European and international partners in the EU’s DEEP re- search projects. In a modular supercomput-


er, various computing modules are coupled together. This en- ables program parts of complex simulations to be distributed over several modules, ensuring that the various hardware prop- erties can be optimally utilized in each case. Its modular con- struction also means that the system is well prepared for inte- grating future technologies such as quantum computing or neuro- morphic modules, which emulate the neural structure of a biologi- cal brain. In its basic configuration,


JUPITER will have an enor- mously powerful booster module with highly efficient GPU-based computation accelerators. Mas- sively parallel applications are accelerated by this booster in a similar way to a turbocharger, for example to calculate high- resolution climate models, devel- op new materials, simulate com- plex cell processes and energy systems, advance basic research, or train next-generation, compu- tationally intensive machine- learning algorithms. One major challenge is the

energy that is required for such large computing power. The av- erage power is anticipated to be up to 15 megawatts. JUPITER has been designed as a “green”


supercomputer and will be pow- ered by green electricity. The en- visaged warm water cooling sys- tem should help to ensure that JUPITER achieves the highest efficiency values. At the same time, the cooling technology opens up the possibility of intel- ligently using the waste heat that is produced. For example, just like its predecessor system JUWELS, JUPITER is set to be connected to the new low-tem- perature network on the Forschungszentrum Jülich cam- pus. Further potential applica- tions for the waste heat from JUPITER are currently being in- vestigated by Forschungszen- trum Jülich. Web: www.fz-juelich.de r

chained, honeycomb lattice design. The researchers laser etched the chained, honeycombed design onto a sample of silica.


Modulating Current Nodes in the design allow


the researchers to modulate the current without bending or stretching the photonic wires, an essential feature needed for con- trolling the flow of light and thus information in a circuit. The new photonic material


overcomes drawbacks of contem- porary topological designs that offered less features and control, while supporting much longer
