Addison Snell Laura Segervall Christopher G. Willard Ph.D. HPC User Site Census: Middleware and Developer Tools


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 examination of middleware and developer tools installed among responding High Performance Computing (HPC) user sites. Our goal in this analysis is to provide an overview of the middleware and developer tools space, including the breadth of packages 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):
      • 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


Middleware and developer tools are software packages that are employed in support of primary applications, but which are not primary applications in of themselves. 797 HPC sites provided data for this analysis, yielding 1,163 mentions of middleware or developer tools or their categories. Middleware is a diverse arena, not only in the types of tools that are classified as middleware or development tools, but also in the many packages themselves named by respondents to our survey. Only two named packageseach accounted for over five percent of total mentions of primary middleware, and only three more were over three percent.
