Addison Snell Laura Segervall Christopher G. Willard Ph.D. HPC User Site Census: System Configurations and Technologies


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 HPC systems and technologies installed among responding HPC user sites. Our goal in this analysis is to provide an overview of how HPC systems are configured, including the breadth of technologies 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
The majority of HPC systems deployed are distributed-memory architectures, particularly clusters and blades. Dual-socket nodes remain common. Intersect360 Research continues to see increases in the amount of memory configured per node and the connection rate of accelerators.
