Hello,
I have two identical systems, down to the sticks of memory manufactures, CPU's, motherboards, hard drives, etc. They are Dual Xeon Quad Core E5450's with 4GB of RAM on an Intel 5100 chipset. I have one that is running Ubuntu Linux 9.04 x64, and using the 6.2.18 BOINC client. It gives me the following CPU Benchmark numbers: 2,678 Floating Point MIPS 11,921 Integer MIPS The other is running Windows Server 2008 x64, and using the 6.6.20 BOINC client. It gives me the following CPU Benchmark numbers: 2,710 Floating Point MIPS 8,175 Integer MIPS Why on earth would the Floating Point MIPS numbers hardly change between the OS's & BOINC versions, but the Integer MIPS numbers drop by around 45%??? It doesn't make any sense to me. |

You shouldn't try to use raw benchmarks for comparison between different platforms. It's a complete waste of time.
If you want to draw comparisons, try computing credit per CPU second. |

It doesn't make any sense to me. You should better ask Berkeley (or maybe the Ubuntu people) why they are releasing versions of Boinc with so inconsistent benchmarks. I can only confirm that 6.2.18 which comes with Ubuntu 9.04 and 6.2.14 which came with Ubuntu 8.10 were actually showing those exaggerated benchmarks (I use a Q6600 with 20 % OC and I see about the same numbers as yours). After seeing 6.2.14 doing that I installed 6.2.15 which had a normal benchmark, i.e. similar to the Windows one. When my beta 9.04 will have been refreshed with the official version I will install Boinc 6.2.19 to see if it is better. Cheers. Jean. |
