It allows one more options when compiling a kernel for CPU families. Complete list included at the bottom of this post. I tested it using three different x86_64 machines running a generic x86-64 kernel and an otherwise identical kernel running with the optimized gcc options.<br /><br />Conclusion:<br />There are small but real speed increases using a make endpoint to running with this patch.<br /><br />Patch: <br />http://repo-ck.com/source/gcc_patch/kernel-36-gcc47-1.patch.gz<br /><br />Details:<br />1) Three test machines: Intel Xeon X3360, Intel i7-2620M, Intel Core i7-3660K.<br />2) All ran the make benchmark (linked below) 35 times while booted into a 'generic' kernel. Then all ran the same make benchmark 35 times after booting into an optimized kernel. Below are the optimizations chosen for each machine.<br />2a) X3360 = core2<br />2b) i7-2620M = corei7-avx<br />2c) i7-3660K = core-avx-i<br />3) Analyzed resulting distributions for statistical significance via ANOVA plots that clearly show statistically significant albeit small differences.<br /><br />Links to ANOVA plots:<br />http://s19.postimage.org/68urcofzn/corei7_avx.png<br />http://s19.postimage.org/ozwomuak3/core_avx_i.png<br />http://s19.postimage.org/d0l6fj4z7/core2.png<br /><br />References:<br />Bash script that controls the benchmark: https://github.com/graysky2/bin/blob/master/bench<br />Log file generated by script: http://repo-ck.com/bench/compile_time_optimization.txt.gzgrayskyhttps://www.blogger.com/profile/16133632514577609343noreply@blogger.comtag:blogger.com,1999:blog-6469704299235308349.post-65633561317139253122012-12-08T23:36:01.384+11:002012-12-08T23:36:01.384+11:00Get yourself an E5.

B...Many thanks, Con, for sharing these two with us.<br />Both are impressive contributions to encourage you in moments...<br /><br />Con, do you have a mascot or a special attitude to one of your countries animals? Maybe we can improve Teb's T-shirt idea by having a Tux kissing your mascot? And replacing the 'other' with 'ONLY' :-)<br /><br />@graysky: Great and beautiful work! Could you provide the approx. size of the video-benchmarked file? Just to find how it fits into the RAM of the tested unicore Athlon system (1GB) when decompressed. And how is the base utilisation of memory used by this system and desktop when running the tests, is it swapping? What desktop do you use when testing?<br /><br />Best wishes to all of you!<br /><br />ManuelAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-6469704299235308349.post-4357395249670657832012-11-14T02:34:59.621+11:002012-11-14T02:34:59.621+11:00My other scheduler?
