Models and frequencies make the MIPS Dhrystone value of evilkats seem strange. It is even higher than my hyperprocessor. evilkats any particularities on your rig, as your value seems stellar. ![]() [Edit 1 times, last edit by Hypernova at Oct 7, 2010 2:31:20 PM] |

Linux is much better at it Fine but how. The code is compiled for the CPU. Once Linux has loaded it in RAM and it executes it is a matter of processor performance. I am talking only of the benchmarks. It is CPU and RAM. It is hardware that runs the benchmark not Linux. The only thing I see is that the executable code compiled under Linux is much more effective that the one compiled under Windows. But why. The code is generated for a given processors using the right instruction libraries available to carry the mathematical calculations. I really miss here a clear explanation. ![]() |

this is what a few of my system looks like:
----------------------------------------Benchmark results: Number of CPUs: 16 2538 floating point MIPS (Whetstone) per CPU 6509 integer MIPS (Dhrystone) per CPU quantity vs quality I guess ![]() |

evilkats BOINC client version 6.10.58 for x86_64-pc-linux-gnu Processor: 4 GenuineIntel Intel(R) Core(TM)2 Quad CPU Q9550 @ 2.83GHz [Family 6 Model 23 Stepping 7] 2769 floating point MIPS (Whetstone) per CPU 14393 integer MIPS (Dhrystone) per CPU I sense a problem here. Models and frequencies make the MIPS Dhrystone value of evilkats seem strange. It is even higher than my hyperprocessor. evilkats any particularities on your rig, as your value seems stellar. It is strange becase the same banchmarks on the Windows XP are 2977 floating point MIPS (Whetstone) per CPU 5923 integer MIPS (Dhrystone) per CPU These came from the 2 identical HP desktops. One is running Windows XP, and on the other I installed Ubuntu 10.04 64-bit. What I do notice on Linux, is that my claimed points are almost always higher than what I receive. ![]() |

The code is generated for a given processors using the right instruction libraries available to carry the mathematical calculations. I really miss here a clear explanation. Code Libraries and compilers! No one writes an entire program. The program they write calls code. written by others. The efficiency of that other code makes a difference. http://en.wikipedia.org/wiki/Library_%28computing%29 People write abstract code to solve problems. The efficiency of the compiler determines the exact steps that are executed on a CPU. How efficient a compiler is makes a big difference in the speed of the created program. These are different in Windows and Linux. http://en.wikipedia.org/wiki/Compiler As to the specifics of what makes Windows so inefficient, this would take some careful research, which is made difficult without the source code. |

Well, I'm wondering that my results are not as bad as I thought...
----------------------------------------Although my Macbook is already 3 years old, the results don't seem to be SO bad in comparison... OS: Mac OS 10.6 32 Bit BOINC version: 6.10.17 CPU: Intel T7400 Core 2 Duo 2.16 GHz Number of CPUs: 2 2132 floating point MIPS (Whetstone) per CPU 6996 integer MIPS (Dhrystone) per CPU ![]() |
