2015 HPC User Site Census: Applications

July 2016
This report is part of our HPC User Site Census series and provides an examination of the primary application software found at a sample of HPC user sites. We surveyed a broad range of users about their current computer system installations, storage systems, networks, middleware, and applications software supporting these computer installations.
 
Our goal in this analysis of applications is to examine the suppliers, products, and primary usage of the application software packages in use at all HPC sites. Using our primary usage categories, we have created two super segments: High Performance Technical Computing (HPTC) applications and High Performance Business Computing (HPBC) applications. We examine these two super segments in this report.
 
Key findings of the Site Census surveys include the following:
 
  • 791 unique packages representing 2,044 mentions were listed by all sites: 574 were HPTC applications and 217 were HPBC applications. About three-fourths of HPTC packages and nine-tenths of HPBC packages are mentioned only once in the survey, indicating the diversity of application needs and the experimental nature of the HPC market.
  • Chemistry, biosciences, fluid dynamics, structural analysis, and business intelligence were the top five HPC usage categories for application software. Structural analysis returned to the top five after having been displaced by weather/environmental modeling. The broad category of business Intelligence was the only HPBC usage category in the top five.
  • The leading application software packages in HPTC were Ansys’ Fluent, Gaussian, GROMACS,  NAMD, and VASP. All are chemistry applications except Ansys’ Fluent. The leading application software packages in HPBC were Hadoop and those provided by Oracle and Amazon. All of these top packages were used at multiple sites.
  • Commercial sites still prefer ISV-based applications over open-source applications. For HPTC applications, 56% of the applications mentioned were ISV-based applications compared to 20% open-source. For HPBC, 39% of the applications mentioned were ISV-based, compared to 10% open-source.
