Sun Fire X2200 M2 running Fluent CFD Beats Woodcrest & Clovertown
Friday Mar 30, 2007
The Sun Fire X2200 M2 server beats Woodcrest on large CFD models. The X2200 M2 Cluster beats all currently posted Opteron cluster results (dual core HP XC4000 2.2GHz, HP DL145 G2 2.2GHz, HP XW9300 2.4GHz, and HP DL585 2.6GHz) for all "cpu" levels and for all test cases. All clusters had the high performance Infiniband interconnects.
The X2200 M2 beats the IBM X3650 2.66GHz quad core Clovertown across the board at all cpu levels and for all test cases.
Tests were run on the official version of Fluent (lnxamd64 V6.3.26 build). The Sun Opteron server numbers were generated under 64-bit SUSE SLES 9 SP 3. Sun many customers that use Solaris, Linux, and windows so we show benchmarks on all of these.
Although the X2200 M2 cluster has the best performance on the larger and more complex tests, "FL5L3". It is most closely representative of actual customer benchmarks (requires over 9GB of memory, best run using several cpu's). FL5L3 simulates turbulent flow through a transition duct.
Note that the X2200 M2 cluster results shown in following table are consistently better than those obtained on the two Woodcrest cluster systems at the same "cpu" levels and for all indicated "cpu" levels (4 to 32).
The efficiency of the Sun X2200 M2 cluster is superb at well above 90% up to 32 cores. This essentially perfect scalability is contrasted with the Woodcrest clusters where scalability has dropped off and efficiency is below 70% at and above 4 cores.

Benchmark Description
Nine industrial CFD applications ranging in size from 32,000 to 10,000,000 cells have been selected to demonstrate the performance of FLUENT on a variety of hardware platforms. 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 problems selected represent a range of simulations typical of those which might be found in industry. The principal objective of this benchmark suite is to provide comprehensive and fair comparative information of the performance of FLUENT on available hardware platforms.
