Yesterday we heard the German HLRS center will build a new supercomputer
with 10,000 64-core AMD EPYC "Rome" processors and now there's word that the future Perlmutter supercomputer from the US Department of Energy (DOE) will feature the unannounced AMD EPYC "Milan" and a future NVIDIA "Volta-Next" GPU. The DOE isn't at liberty to disclose the core counts for Milan, which uses a 7nm+ Zen 3 chip, so their slides were based on the specifications of Rome. Each node will feature four NVIDIA "Volta-Next" GPUs, but similarly, the DOE isn't allowed to disclose specifications.
The Rome processors AMD recently announced will come with the 7nm process and the Zen 2 microarchitecture, while the Milan CPUs will come with the Zen 3 microarchitecture built on the 7nm+ process. The slide also lists 8 channels of DDR memory with >=256 GiB of memory per node, but the speaker again specified that the memory capacity figure is based on Milan's specifications either matching or exceeding that of Rome.
