Sun Fire X2270 M2 Achieves Leading Single Node Results on ANSYS FLUENT Benchmark

Oracle's Sun Fire X2270 M2 server produced leading single node performance results running the ANSYS FLUENT benchmark cases as compared to the best single node results currently posted at the ANSYS FLUENT website. ANSYS FLUENT is a prominent MCAE application used for computational fluid dynamics (CFD).

  • The Sun Fire X2270 M2 server outperformed all single node systems in 5 of 6 test cases at the 12 core level, beating systems from Cray and SGI.
  • For the truck_14m test, the Sun Fire X2270 M2 server outperformed all single node systems at all posted core counts, beating systems from SGI, Cray and HP. When considering performance on a single node, the truck_14m model is most representative of customer CFD model sizes in the test suite.
  • The Sun Fire X2270 M2 server with 12 cores performed up to 1.3 times faster than the previous generation Sun Fire X2270 server with 8 cores.

Performance Landscape

Results are presented for six of the seven ANSYS FLUENT benchmark tests. The seventh test is not a practical test for a single system. Results are ratings, where bigger is better. A rating is the number of jobs that could be run in a single day (86,400 / run time). Competitive results are from the ANSYS FLUENT benchmark website as of 25 June 2010.

Benchmark Description

The following description is from the ANSYS FLUENT website:

The FLUENT benchmarks suite comprises of a set of test cases covering a large range of mesh sizes, physical models and solvers representing typical industry usage. The cases range in size from a few 100 thousand cells to more than 100 million cells. Both the segregated and coupled implicit solvers are included, as well as hexahedral, mixed and polyhedral cell cases. This broad coverage is expected to demonstrate the breadth of FLUENT performance on a variety of hardware platforms and test cases.

The performance of a CFD code will depend on several factors, including size and topology of the mesh, physical models, numerics and parallelization, compilers and optimization, in addition to performance characteristics of the hardware where the simulation is performed. The principal objective of this benchmark suite is to provide comprehensive and fair comparative information of the performance of FLUENT on available hardware platforms.

About the ANSYS FLUENT 12 Benchmark Test Suite

    CFD models tend to be very large where grid refinement is required to capture with accuracy conditions in the boundary layer region adjacent to the body over which flow is occurring. Fine grids are required to also determine accurate turbulence conditions. As such these models can run for many hours or even days as well using a large number of processors.
