Bench CFX/Fluent with xeon5520
I've run two different case (one Fluent with 1M cells and one with CFX with 2M cells) on single CPU's.
The results are: Testcase: Fluent 6.2, MRF, ca 1M cells Start with 200iter, measure from 150iter Time CPU 23m30s core2 3.16GHz 24m36s xeon 3GHz 27m50s core2 3.0GHz 28m02s xeon5520(nehalem) 2.26GHz 29m43s core2 2.8GHz Testcase: CFX 12, ca 2M cells 20iterations Time CPU 1517s xeon5520 (nehalem) 2.26GHz 1296s xeon 3GHz 1603s core2 3.0GHz Thus it seems that nehalem at 2.26GHz is similar to a core2 at 3GHz, I was expecting more from this CPU. Has anyone similar experiance? /Jonas Ps core2 at 2.8Ghz is a oc e6300 (1.86GHz) with 800MHz DDR2 Ds |
The strength of the Nehalem becomes evident when using more than one core on the CPU. Try the benchmarks by running a 2-way parallel run on each machine, or by running the benchmark on a machine where another job is running at the same time.

Thanks for the numbers! Interesting results.
