High-performance, cloud and edge computing

High-performance, cloud and edge computing provide the processing and storage capacity for simulation, analytics and digital services. They are both an enabler of risk analysis and a critical dependency for society. Data and Compute stewards this page for the Nexus Consortium.

01In brief

The short answer.

High-performance, cloud and edge computing provide the processing and storage capacity for simulation, analytics and digital services. Computing capacity determines how fast and at what resolution risks can be modelled. In the Nexus Consortium, Data and Compute stewards its canonical page, and 7 other platforms apply it, including Nexus Foundry as well as Climate and Hazards.

03The method

What high-performance, cloud and edge computing covers.

  1. 01

    Core methods

    parallel and distributed computing; workload scheduling; virtualisation and containerisation; capacity planning; fault-tolerant system design; performance benchmarking.

  2. 02

    Data and instruments

    system performance logs; job scheduler records; energy and cooling telemetry; benchmark results; service availability records.

  3. 03

    Validation

    Systems are tested through benchmarks, load testing and failover exercises. Numerical reproducibility is checked across hardware and software configurations.

  4. 04

    Limits

    Concentration in few providers or regions creates shared points of failure. Energy, water and supply chain constraints limit capacity growth.

  5. 05

    Use in risk decisions

    Computing capacity determines how fast and at what resolution risks can be modelled. Its concentration is itself a systemic dependency for finance, health and government services.

04Reference practice

Computing practice is measured by performance, efficiency and reproducibility.

05In systemic risk work

Compute sets the resolution of what can be known.

Ensemble size, model resolution and the number of scenarios explored are limited by compute. For systemic risk, compute is also a dependency: public services and science rely on a small number of providers. Reproducibility requires recording the software environment and hardware where results depend on them.

  • Record software versions and random seeds.
  • Note when results depend on hardware precision.
  • Assess continuity of access to compute for critical analysis.
  • Applications on Data and Compute and Nexus Foundry.
07Stewardship

Who maintains this page.

Data and Compute stewards high-performance, cloud and edge computing: it keeps this description current and reviews how the method is applied across the platforms.

08Key terms

Terms used on this page.

Each term as this page uses it. Where a standard-setting body defines the term, the wording follows that body.

11Questions

Questions and answers.

Why does one institution host every method page?
GCRI hosts the STEM Commons so that each method has one canonical description. Platforms link to it rather than repeat it, which keeps definitions consistent.
How do I suggest a correction to a method page?
Write to integrity@therisk.global with the passage and the reason.

The current service level is R0: information and enquiries. An enquiry receives a reference and names the next step; applications, payments, compute allocations and registrations open only when their team, terms and review capacity exist.
