“I can’t give you all the specs, but is at least 10× greater than Sierra performance on average figures of merit,” said Quinn.

“I cut these words out of investors document and that’s what it says: it’s a 3D chiplet design with AMD CDNA3 GPUs, Zen 4 CPUs, cache memory and HBM chiplets.” “It’s the first time we’ve publicly stated this,” said Quinn, associate director for HPC at LLNL. Now, we know a bit more about that AMD hardware: El Capitan will be powered by AMD’s forthcoming MI300 APUs. A render of El Capitan.Įl Capitan, an HPE-built, AMD-powered exascale system, is on track to deliver at least 2 exaflops of peak performance courtesy of tightly packaged AMD GPUs and CPUs bundled into HPE Cray XE racks and tied together with Slingshot-11 networking. Quinn revealed that AMD’s forthcoming MI300 APU would be the computational bedrock of El Capitan, which is slated for installation at LLNL in late 2023.

Since 1987 - Covering the Fastest Computers in the World and the People Who Run ThemĪdditional details of the architecture of the exascale El Capitan supercomputer were disclosed today by Lawrence Livermore National Laboratory’s (LLNL) Terri Quinn in a presentation delivered to the 79th HPC User Forum at Oak Ridge National Laboratory (ORNL).
