Sun Blade X6275 M2 Delivers Best Fluent (MCAE Application) Performance on Tested Configurations

This Manufacturing Engineering benchmark highlights the performance advantage the Sun Blade X6275 M2 server module offers over IBM, Cray, and SGI solutions as shown by the ANSYS FLUENT fluid dynamics application.

A cluster of eight of Oracle's Sun Blade X6275 M2 server modules delivered outstanding performance running the FLUENT 12 benchmark test suite.

  • The Sun Blade X6275 M2 server module cluster delivered the best results in all 36 of the test configurations run, outperforming the best posted results by as much as 42%.
  • The Sun Blade X6275 M2 server module demonstrated up to 76% performance improvement over the previous generation Sun Blade X6275 server module.

Performance Landscape

In the following tables, results are "Ratings" (bigger is better).
Rating = No. of sequential runs of test case possible in 1 day: 86,400/(Total Elapsed Run Time in Seconds)

The following table compares results on the basis of core count, irrespective of processor generation. This means that in some cases, i.e., for the 32-core and 64-core configurations, systems with the Intel Xeon X5670 six-core processors did not utilize quite all of the cores available for the specified processor count.

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.

Key Points and Best Practices

  • ANSYS FLUENT has not yet been certified by the vendor on Oracle Enterprise Linux (OEL). However, the ANSYS FLUENT benchmark tests have been run successfully on Oracle hardware running OEL as is (i.e. with NO changes or modifications).
  • The performance improvement of the Sun Blade X6275 M2 server module over the previous generation Sun Blade X6275 server module was due to two main factors: the increased core count per processor (6 vs. 4), and the more optimal, iterative dataset partitioning scheme used for the Sun Blade X6275 M2 server module.
