I will present the exascale system JUPITER of Jülich Supercomputing Centre (JSC), the first exascale system in Europe. A joint European and German effort, JUPITER provides computing resources to the diverse European and German scientific communities. After a brief introduction into HPC also for HEP, I will discuss the development of the project and describe the system architecture and performance. By providing over one exaflop, JUPITER increased the resources of the JSC by about a factor of twelve. Such an abrupt increase poses a challenge to the user communities to adapt their software suites to take full advantage of JUPITER. I will briefly outline JSC's approach to support the user communities in their efforts. Finally, I will present several other architectures deployed or planned at JSC, ranging from quantum computing or analog computers to neuromorphic architectures.
