HPC Software Survey: Primary Applications— Weather and Climate Modeling


Intersect360 Research surveyed the High Performance Computing (HPC) user community on their software usage for HPC. The complete study analyzes users’ current operating systems, middleware, developer tools, and primary applications across 11 different application domains, including:

  • the overall mix of in-house, open-source, and commercial software
  • the mix of public cloud versus on-premises computing, by application
  • scalability and performance on various processing elements, by application domain
  • the overall adoption of machine learning.

Our goal in this analysis is to provide an in-depth analysis of how HPC software trends. Intersect360 Research surveyed members of the HPC user community worldwide across industry, government, and academia.  The survey was conducted in the fourth quarter of 2021 and received responses from 238 qualified sites, yielding tens of thousands of data points for analysis with respect to HPC software.

Intersect360 Research defines HPC as the use of servers, clusters, and supercomputers—plus associated software, tools, components, storage, and services—for scientific, engineering, or analytical tasks that are particularly intensive in computation, memory usage, or data management. Intersect360 Research reports available in this HPC Technology Survey report series include the following segmentations:

  • Operating Systems and Middleware: including operating systems, HPC job management tools, workflow and workload management tools, and software for cluster management, monitoring, and provisioning
  • Compilers and Developer Tools: including languages, compilers, and programming environments for HPC software development
  • AI Adoption: including machine learning frameworks and current levels of organizational AI engagement
  • Primary Application Software: 11 distinct reports covering applications used, typical and maximum job scalability, affinity to cloud computing, and impressions of performance by processor type, for 11 application domains, as follows:
    • Primary Application Software—Biosciences: including pharmaceuticals, biochemistry, genomics, agricultural engineering, cryo-EM, etc.
    • Primary Application Software—Business Analytics
    • Primary Application Software—Chemistry
    • Primary Application Software—Computational Fluid Dynamics (CFD)
    • Primary Application Software—Engineering: including computer-aided engineering (CAE), finite element analysis (FEA), noise-vibration-harshness testing (NVH), materials science, etc.
    • Primary Application Software—Finance: including banking, trading, pricing, risk management and value-at-risk (VaR), econometric modeling, insurance, etc.
    • Primary Application Software—Geophysics: including seismic modeling, reservoir simulation, geology, etc.
    • Primary Application Software—Physics: including pharmaceuticals, biochemistry, genomics, agricultural engineering, cryo-EM, etc.
    • Primary Application Software—Scientific Research: including general fields of scientific inquiry not covered elsewhere
    • Primary Application Software—Visualization
    • Primary Application Software—Weather and Climate Modeling: including earth science and ocean modeling

This report provides a detailed examination of primary application software in Weather and Climate Modeling. 82 respondents provided data on applications in the Weather and Climate Modeling category, for a total of 118 unique application mentions, an average of 1.44 applications per respondent, concentrated into relatively few applications. We listed six primary applications for end users to select from, based on their appearance in prior open-response surveys. Additionally, we received 10 write-ins of additional applications; most of which were mentioned by only one respondent. Weather and Climate Modeling applications showed more scalability in typical and maximum usage than application in any other HPC domain. Intersect360 Research clients should carefully heed the data and insights in this report in planning their future developments for all HPC technologies and services.
