Benchmarks Overview

Ansys benchmarks provide comprehensive and fair comparative information concerning the performance of Ansys solvers on available hardware platforms. The benchmarks can be used to compare performance of different hardware platforms when running Ansys solvers. To accomplish this goal, Ansys provides the suite of simulation cases that make up the Ansys benchmark suite to its hardware partners for their use in benchmarking hardware performance; then the data is reported to Ansys and compiled for this site. Cases are selected to represent typical usage and cover a range of mesh sizes and physical models.

Benchmarking Terminology

Ansys Fluent Benchmarks

This benchmark suite provides Ansys Fluent hardware performance data measured using sets of benchmark problems selected to represent typical usage. The Ansys Fluent benchmark cases range in size from a few hundred- thousand cells to more than 100 million cells. The suite contains both pressure-based (segregated and coupled) and density-based implicit solver cases using a variety of cell types and a range of physics. These cases are used by hardware vendors to benchmark their hardware systems and the resulting performance data is then included in these pages. For further descriptions of benchmark problems, please go to the benchmark page related to the case you are interested in.

Ansys Mechanical Benchmarks

This benchmark suite provides Ansys Mechanical hardware performance data measured using sets of benchmark problems selected to represent typical usage. The Ansys Mechanical benchmark cases range in size from 650,000 degrees of freedom to over 14 million degrees of freedom. The suite contains both PCG and Sparse equation solver benchmark cases as well as covering a wide variety of analysis types including static, transient, modal, cyclic symmetry modal and harmonic. Additionally, both thermal and structural physics are covered. These cases are used by hardware vendors to benchmark their hardware systems and the resulting performance data is then included in these pages. For further descriptions of benchmark problems, please go to the benchmark page related to the case you are interested in.

Benchmarking Terminology

Rating

Rating is the primary metric used to report performance results of the benchmarks. It is defined as the number of benchmarks that can be run on a given machine (in sequence) in a 24 hour period. It is computed by dividing the number of seconds in a day (86400 seconds) by the number of seconds required to run the benchmark. A higher rating means faster performance.

Speedup

Speedup is the ratio of wall-clock time required to complete a given calculation using a single processor to that of the equivalent calculation performed on a concurrent machine. Its value ranges from 1 to the number of processors used for the parallel run. When the speedup is equal to the number of processors used, the speedup is called perfect or linear. Sometimes the speedup will exceed the number of processors. This is referred to as super-linear speedup, and is often caused by the availability and use of larger amounts of "fast" memory (e.g. cache or local memory) compared to the single processor run.

Efficiency

Efficiency is the speedup normalized by the number of processors used, presented as a percentage. It indicates the overall utilization of the CPUs during a parallel calculation. An efficiency of 100% indicates that each CPU is completely occupied with computation during the course of a run, and corresponds to a linear speedup. An efficiency of 60% indicates that each CPU is performing useful computation only 60% of the time. The remaining time is spent waiting for other functions, such as parallel communication or work on other processors, to complete.
