JEDI

JUPITER Exascale Development Instrument

JEDI is the first module of the exascale supercomputer JUPITER and was installed in April 2024 by the ParTec-Eviden supercomputer consortium .

The JEDI development system is one of the first systems in the world to use the latest generation of accelerators from NVIDIA: the NVIDIA GH200 Grace Hopper Superchip, which combines the NVIDIA Hopper GPU and the NVIDIA Grace CPU on a single module. Based on Eviden’s latest BullSequana XH3000 architecture, the system includes its highly efficient hot water cooling system, Direct Liquid Cooling, which requires significantly less energy than conventional air cooling, and allows the heat generated to be reused downstream.

The JUPITER precursor JEDI already has the same equipment as the subsequent JUPITER booster module. Scientists are able to access the hardware at an early stage of development as part of the JUPITER Research and Early Access Program (JUREAP) in order to optimise their codes. In doing so, they are supported by experts from the Jülich Supercomputing Centre.
