AMD's MI300 Zen 4/CDNA 3 3D processors will power the 2+ Exaflop El Capitan Supercomputer
AMD's taking their 3D chipmaking technology to new heights with their MI300 series accelerators, bringing together CPU and GPU compute to create an APU (Accelerated processing unit) that can take AMD's supercomputing performance to new heights while remaining power-efficient and spatially efficient.
The Lawrence Livermore National Laboratory (LLNL) has confirmed that their El Capitan supercomputer will be powered by AMD's MI300 accelerators, and that the system is on track to deliver at least 2 exaflops of of peak performance.
AMD's MI300 chips are a 3D chiplet based accelerator design that features both Zen 4 CPU cores and a CDNA 3 graphics component. Add on a lot of cache memory and HBM chiplets, and El Capitan's chips will be able to pack a tonne of performance into a small space and deliver breakthrough system performance. The system's projected to deliver over two Exaflops of peak performance with under 40 megawatts of power. This tight power budget is to reduce the running costs of the supercomputer.
AMD's MI300 APUs leverage AMD's 4th generation infinity architecture, and El Capitan will interconnect a huge number of AMD MI300 APUs using HPE Cray XE system racks and Slingshot-11 networking. AMD provides the compute, and Cray help to tie everything together.
AMD revealed their MI300 accelerator at their Financial Analysts day this month, highlighting how it utilises AMD's latest processors packaging technologies to their fullest. Multiple chip designs are brought together within a single MI300 chip, making them a strong option for all kinds of computational tasks.
