BRII Comparisons

To highlight the benefits users can expect from transitioning to the new petaflop system BRII, we gathered performance data of common benchmarks and applications on the other IU systems.

We plan to provide data on the following benchmarks/applications:

The HPC-systems benchmarked include:

  • BigRed
  • Quarry
  • BRII Test System (This system is similar in architecture to Big Red II but smaller in size. The system is provided by Cray for testing purposes.)
