High Performance Computing

High Performance Computing is a Sub-Project of the OCP Server Project serving the HPC, supercomputing and high performance data analytics markets with open hardware platforms from system level down to silicon. It focuses on modular, flexible and composable heterogeneous multi-processor systems that scale to thousands of processors energy-efficiently, with data centricity measured by the Flops : Bytes/s : Bytes Depth ratio and success judged by an Application Performance Density Metric. Work proceeds in three phases - metrics, white-paper concepts, demonstrator prototypes - stays within the rack, coordinates with Rack & Power, and emphasizes HPC in the cloud. Workstreams cover interconnect, system management, thermal management and emulation FPGA module design.

About This Sub-Project

High Performance Computing (HPC) is a Sub-Project under the OCP Server Project.

The HPC project has been established in the Open Compute Project to service the needs of the High Performance Computing, Supercomputing and High Performance Data Analytics segments of the computing industry, and to serve them with open hardware platforms delivering solutions in the market from system level down to silicon.

Approach

This project will proceed in three phases, in chronological order: defining metrics, creating white paper concepts, and building demonstrator prototypes. Radical ideas will be encouraged, including potentially testing them out to prove their viability. These ideas will be open for all other OCP Projects to observe and pull from as they see fit.

The aspect of efficient interoperability between the different heterogeneous processors and memory/storage media will also be considered, in a way that contributes to the Hardware Management Project.

While leveraging existing projects within OCP is highly desired, the HPC project shall not be constrained by them, but instead inspired by them. A particular area of focus will be HPC in the cloud and shared cloud HPC infrastructures.

The project will also consider how to successfully transfer the technology outputs from the phase 1 and phase 2 efforts to other OCP groups.

Workstreams

Scope

The project will focus on modular, flexible & composable heterogeneous multi-processor systems that can scale to hundreds or thousands of processors in an energy-efficient way to service the needs of the target market.

  • Data centricity : a critical factor, with a focus on supporting the classic compute ratio metric of Flops : Bytes/s : Bytes Depth. True composability will be demonstrated when this ratio can be easily tuned to an HPC application’s specific needs.
  • Measure of success : the Application Performance Density Metric, which acts as a proxy for many other metrics including efficiency and cost, assuming the proposed solutions deliver on the modular, flexible & composable requirements. Other sub-metrics will provide lower-level measurements that drive toward the best application performance.
  • Rack-level boundary : the project constrains its efforts to within the rack level of the HPC system and will communicate with the Rack & Power Project on any potential needs that appear to deviate from that project’s efforts.

Welcome to the OCP High Performance Computing (HPC) Sub-Project.

We have been working on redefining an Open Industry Standard Computing Architecture for today’s computing needs and it’s called the “High Performance Compute Module – Wall of Compute” HPCM-WoC. Our most recent efforts have culminated in choosing a POC for an ASIC Emulation Application using the HPCM-WoC architectural approach.

We have created a proposal for this POC in response to the DOE/ORNL’s New Frontiers RFP, which you are welcome to review here : –

A Platform for the Development & Deployment of Domain Specific Supercomputers

We also presented an overview of this POC at the OCP Global Summit – 2024 here : – Building a Digital Twin, Asic Emulation Platform, Using the OCP HPCM Wall of Compute – Recording Slides

For more details on the motivation behind the OCP HPC SubProject’s efforts as well as a brief overview of the HPCM Module, see : –
