AMD has true provided a critical take in the HPC sector with its subsequent-era EPYC and Radeon accelerators powering the 2 Exaflop El Capitan supercomputer of the U.S. Division of Energy or DOE, which must peaceful be operational by 2023.
AMD’s EPYC Genoa & Radeon Instinct HPC Accelerators To Pressure 2 Exaflop ‘El Capitan’ Supercomputer
All three giants including Intel, AMD & NVIDIA had been competing to take the contract for DOE’s most unique supercomputer, but it surely seems admire AMD obtained on each the CPU & GPU entrance. The El Capitan supercomputer may possibly be constructed by HPE’s Cray supercomputing division which can possibly well possibly verbalize the next-era accelerators from AMD to raise this exaflop monster to life by 2023. The supercomputer may possibly be deployed on the Lawrence Livermore Nationwide Laboratory and may possibly possibly well possibly moreover very properly have the capability to connect up to 2 quintillion calculations per 2d.
“We inquire when or now not it is brought to the laboratory in 2023, this may possibly well possibly be the fastest supercomputer on the earth,” said Invoice Goldstein, director of the Livermore lab
All the scheme will cost $600 million to assemble and may possibly possibly well possibly moreover very properly be on the least sixteen instances faster than the Sierra (IBM Energy 9 + NVIDIA Volta) supercomputer that’s in the meanwhile deployed at LLNL. As for the specs of the scheme itself, we know that EPYC Genoa may possibly be powering the CPU facet while a subsequent-era Radeon Instinct accelerator will strength the GPU facet of issues. The total scheme will bask in lower than 40MW when it turns into operational.
The next are a list of AMD technologies to be included in the El Capitan supercomputer:
- Subsequent-era AMD EPYC processors, codenamed “Genoa” featuring the “Zen four” processor core. These processors will support subsequent-era memory and I/O subsystems for AI and HPC workloads,
- Subsequent-era Radeon Instinct GPUs in step with a peculiar compute-optimized structure for workloads including HPC and AI. These GPUs will verbalize the next- era excessive bandwidth memory and are designed for optimum deep learning performance,
- The 3rd Gen AMD Infinity Architecture, which is able to provide a excessive-bandwidth, low latency connection between the four Radeon Instinct GPUs and one AMD EPYC CPU included in every node of El Capitan. As properly, the 3rd Gen AMD Infinity Architecture involves unified memory across the CPU and GPU, easing programmer make a choice up entry to to accelerated computing,
- An enhanced model of the originate-source ROCm heterogenous programming ambiance, being developed to tap into the combined performance of AMD CPUs and GPUs, unlocking most performance.
AMD EPYC Genoa – Post-7nm Zen four Cores, SP5 Socket Platform, DDR5 Memory, PCIe 5.zero Protocol
The AMD EPYC Genoa processors in step with the Zen four core structure had been a mystery unless AMD officially unveiled them of their most unique roadmap in the direction of the EPYC Rome originate. Right now in-arrangement with a deliberate originate for 2021, the Genoa lineup will elevate a peculiar purpose of aspects to the server landscape.
AMD provided that EPYC Genoa may possibly be acceptable with the unusual SP5 platform which brings a peculiar socket, so SP3 compatibility will exist up unless EPYC Milan. The EPYC Genoa processors will moreover characteristic support for trace spanking unusual memory and unusual capabilities. It seems admire AMD would indubitably be jumping on board the DDR5 bandwagon in 2021. It’s miles moreover mentioned that unusual capabilities may possibly be provided on EPYC Genoa which sounds admire a trot on the unusual PCIe 5.zero protocol which is able to double the bandwidth of PCIe four.zero, offering 128 Gbps link speeds across an x16 interface.
Summing all the pieces up for EPYC Genoa, we are taking a stare upon the next main aspects:
- Post-7nm Zen four cores
- SP5 Platform With Original Socket
- PCIe 5.zero Make stronger
- DDR5 Memory Make stronger
- Originate in 2021
On the Radeon Instinct facet, we are indubitably taking a stare upon a grand highly efficient and possibly sub-7nm GPU basically based mostly fully graphics accelerator. AMD is in the meanwhile prepping to originate its Radeon Instinct Mi100 accelerator which is codenamed ‘Arcturus’ and reportedly aspects up to 8192 circulate processors and 32 GB of HBM2e memory.
The GPU is unquestionably a beast by itself, but it surely’s deliberate for a 2020 originate and to arrangement tremendous that they proceed to be future proof, the El Capitan supercomputer may possibly be indubitably deploying one thing more moderen than the Radeon Instinct Mi100. The true graphics card or accelerator has now not been mentioned, but it surely is mentioned that the unusual GPU presents a peculiar compute structure which is:
- Optimized for HPC and AI
- Intensive Mixed Precision Ops for Optimized Deep Studying Efficiency
- Subsequent-Generation High Bandwidth Memory
- Maximize Efficiency With Multi-GPU Scaling
In step with the featureset, we are indubitably taking a stare upon one thing beyond HBM2e and PCIe Gen four which is able to be readily accessible by 2021 while El Capitan will change into operational in 2023. The GPU is moreover said to be particularly designed for Compute / AI / HPC workloads that intention that it may possibly possibly well be a personalized arrangement for the said phase and now not a chip that you just may possibly possibly well possibly be make a choice up to be aware in the user location, grand admire NVIDIA’s bask in HPC accelerators.
Also, the third main characteristic of El Capitan may possibly be that every AMD CPU / GPU accelerator may possibly be equipped with the third Generation Infinity Cloth interconnect. Talked about as Infinity Cloth 3.zero, the unusual interconnect will allow a excessive-bandwidth & low-latency connection between the CPU & GPU, allow a unified memory across CPU & GPU while the full coherent nature of the platform would support total performance and simplify programming.
In the run posted by AMD, it seems admire every node would beget four Radeon accelerators straight linked to an AMD EPYC Genoa processor by Infinity Cloth 3.zero. It might most likely be worn as properly as to Cray’s bask in Slingshot fabric which in the meanwhile pushes up to 200 Gb/s of bandwidth, but future versions may possibly possibly well possibly offer even more interconnect bandwidth to the El Capitan infrastructure. The difference here is that Slingshot is more of a node-to-node channel while Infinity Cloth is nearer to a CPU-GPU interconnect.

It’s moreover mentioned that there may possibly be cache coherency between the CPU & GPU as a change of true memory which is able to be a mammoth deal for future HPC platforms. A run showcasing advantages of a heterogeneous platform used to be showcased by AMD and shared by Addison Snell over at his Twitter feed which presents us a honest valid advice of what to inquire from the future compute & acceleration platforms. With that said, AMD has its Financial Analyst Day the next day, so we can indubitably inquire more cramped print on Zen four and the said Radeon Instinct accelerators in the direction of the presentation.
