HLRS To Upgrade Supercomputing Capabilities With AMD-Powered Herder System

The High-Performance Computing Center Stuttgart (HLRS) is set to upgrade its supercomputing capabilities with the introduction of Herder, a new system that will feature a combination of CPUs and GPUs from AMD. Specifically, Herder will comprise 1488 Instinct MI430X accelerators and 372 Epyc processors of the upcoming Venice type, which boasts the Zen 6 architecture and 2-nanometer technology from TSMC. This new system marks a departure from the previous Hunter system, which utilized Instinct MI300A accelerators that integrated CPU and GPU on a single carrier.

The Instinct MI430X accelerators will come equipped with 432 GByte of High Bandwidth Memory (HBM4), capable of transmitting 19. 6 TByte → s, resulting in a system-wide total of nearly 643 TByte of HBM4. Herder’s architecture will feature two CPUs and eight GPUs on a motherboard from HPE’s new Cray GX5000 platform. The system will also employ liquid cooling, with the waste heat being utilized to heat the Vaihingen campus of the University of Stuttgart. Expected to be operational by the end of 2027, Herder is predicted to deliver a peak performance of at least 340 Petaflops in double-precision ← →
