HPC User Site Census: Weather and Climate Applications

December 4, 2019|Addison Snell, Christopher G. Willard Ph.D., Laura Segervall

EXECUTIVE SUMMARY

Intersect360 Research surveyed the High Performance Computing (HPC) user community to complete its eleventh Site Census study. The study is a look at their
current computer system installations, storage systems, networks, middleware, and application software supporting these computer installations.

This report provides a detailed analysis of the weather, climate, and environment modeling applications installed among respondents to our HPC User Site Census survey. Our
goal in this analysis is to provide an overview of the weather and climate applications space, including the breadth of applications and those that
are most commonly used.

Our Site Census survey results can be found in many reports, including the following:

HPC System Configurations and Technologies
HPC System Vendors Installed
HPC Storage Configurations and Technologies
HPC Storage Vendors Installed
HPC Networking Technologies
HPC Processing Technologies (Including Accelerators)
HPC Operating System Installations
HPC Middleware and Tool Installations
HPC Application Installations (segmented into application domains):
- Biosciences
- Business: Business intelligence, analytics, pattern recognition, ERP, CRM, security, complex event processing, general business
- Chemistry
- Computational Fluid Dynamics (CFD)
- Engineering: Structural analysis, electronic design automation (EDA), general engineering
- Finance and economics
- Geophysics
- Physics
- Scientific research
- Visualization and image analysis
- Weather modeling, climate modeling, environment modeling

Weather simulation and climate modeling are classic applications in HPC, the fifth-most cited application domain in our most recent Site Census survey
analysis, with 186 (7.5%) of the 2,466 mentions. In weather and climate modeling, no ISV applications were mentioned at all from survey respondents.
This is the only application domain in which one of the three application source categories (ISV, in-house, open-source) failed to appear. The majority
of application mentions in the weather and climate category were open-source, accounting for over three-quarters (77%) of application mentions.

Purchase Reports

Single User Access

Single-User Access ($490): Report is for the sole use of one person, such as for forecasting or product planning. Redistribution or sharing of the reports is prohibited, even internally within the purchasing organization or department. Citation of quotes or data, such as on a web site, in a press release, or for enterprise use, requires approval from Intersect360 Research.

Enterprise Usage

Enterprise-Wide Usage ($2,400): Report can be shared within the purchasing organization—for example, across product, strategy, sales, or forecasting teams. This does not extend to partner organizations, such as suppliers or resellers, but does include contractors working for the purchasing organization. Public citation of quotes or data, such as on a web site or in a press release, requires approval from Intersect360 Research. Advisory service clients are granted enterprise-wide usage rights for all reports in the subscribed service (HPC Advisory Service or Hyperscale Advisory Service), but not reprint rights unless purchased separately.

Reprints

Reprints ($4,800 per report): Full redistribution rights for some or all of a report, such as for PR purposes, including email, print, web, or other distribution. The reports may not be edited in any way except as approved by Intersect360 Research (such as to excerpt a section or to highlight particular text). An organization must have enterprise usage of a report—either through individual report purchase or advisory service access—to purchase reprints. Contact Intersect360 Research to purchase.
