Hunter is HLRS’s upcoming next-generation supercomputer. Installation will begin in the fall of 2024, and the new system is expected to begin operating in the first half of 2025.

Hunter is based on the HPE Cray EX4000 supercomputer, which is designed to deliver exascale performance to support large-scale workloads across modeling, simulation, artificial intelligence, and high-performance data analytics. Hunter will transition away from Hawk’s emphasis on CPU processors to make greater use of more energy-efficient GPUs. It will be based on the AMD Instinct™ MI300A accelerated processing unit (APU), which combines CPU and GPU processors together with high-bandwidth memory into a single package, enabling fast data transfer speeds, impressive HPC performance, easy programmability, and great energy efficiency. This will slash the energy required to operate Hunter in comparison to Hawk by approximately 80% at peak performance. Hunter is conceived as a transitional system that will enable HLRS system users to prepare for its upcoming exascale system, Herder, currently scheduled to arrive in 2027.
