Hi Vlastimil, I ported this patch series on top of v6.17 and ran some benchmarks: will-it-scale, hackbench, redis, unixbench and kernbench. I ran the benchmarks on Intel Granite Rapids (480 cores), AMD Turin (512 cores) and ARM (80 cores)
Summary of the results: - Significant change (meaning >10% difference between base and experiment) on will-it-scale tests in AMD. - No significant change on other benchmarks ran. Summary of AMD will-it-scale test changes: Number of runs : 15 Direction : + is good | | MIN | MAX | MEAN | MEDIAN | STDDEV | |:-----------|:-----------|:-----------|:-----------|:-----------|:-----------| | brk1_8_processes | BASE | 7,667,220 | 7,705,767 | 7,682,782 | 7,676,211 | 12,733 | | TEST | 9,477,395 | 10,053,058 | 9,878,753 | 9,959,360 | 182,014 | | % | +23.61% | +30.46% | +28.58% | +29.74% | +1,329.46% | | brk1_8_threads | BASE | 1,838,468 | 1,890,873 | 1,864,473 | 1,864,875 | 18,406 | | TEST | 1,464,917 | 1,668,207 | 1,608,345 | 1,654,578 | 70,558 | | % | -20.32% | -11.78% | -13.74% | -11.28% | +283.34% | | brk1_128_processes | BASE | 65,018,211 | 65,603,366 | 65,285,348 | 65,103,197 | 232,885 | | TEST | 51,287,801 | 52,161,228 | 51,647,807 | 51,509,505 | 277,326 | | % | -21.12% | -20.49% | -20.89% | -20.88% | +19.08% | | brk1_256_processes | BASE | 15,186,881 | 15,239,120 | 15,210,265 | 15,205,809 | 15,850 | | TEST | 20,478,924 | 23,936,204 | 22,754,698 | 22,771,320 | 1,255,974 | | % | +34.85% | +57.07% | +49.60% | +49.75% | +7,823.72% | | brk1_384_processes | BASE | 11,587,076 | 11,851,775 | 11,765,869 | 11,806,007 | 73,736 | | TEST | 25,464,757 | 29,176,818 | 26,695,946 | 26,563,116 | 1,012,563 | | % | +119.77% | +146.18% | +126.89% | +125.00% | +1,273.23% | | brk1_512_processes | BASE | 14,410,293 | 14,891,082 | 14,775,209 | 14,793,142 | 114,384 | | TEST | 22,918,195 | 29,648,177 | 25,204,321 | 25,128,471 | 1,604,037 | | % | +59.04% | +99.10% | +70.59% | +69.87% | +1,302.32% | | mmap1_8_processes | BASE | 3,164,411 | 3,170,585 | 3,167,590 | 3,167,692 | 2,436 | | TEST | 3,516,242 | 3,756,209 | 3,684,585 | 3,698,731 | 68,659 | | % | +11.12% | +18.47% | +16.32% | +16.76% | +2,718.28% | | mmap1_8_threads | BASE | 627,817 | 632,702 | 630,554 | 629,281 | 1,764 | | TEST | 541,202 | 554,097 | 549,104 | 549,896 | 4,257 | | % | -13.80% | -12.42% | -12.92% | -12.62% | +141.34% | | mmap1_128_processes | BASE | 30,303,429 | 30,736,686 | 30,466,107 | 30,343,821 | 174,985 | | TEST | 9,749,426 | 9,893,331 | 9,823,701 | 9,857,157 | 52,125 | | % | -67.83% | -67.81% | -67.76% | -67.52% | -70.21% | | mmap1_256_processes | BASE | 7,496,765 | 7,546,703 | 7,528,379 | 7,543,246 | 21,465 | | TEST | 10,868,119 | 16,947,857 | 12,695,418 | 11,608,083 | 2,157,787 | | % | +44.97% | +124.57% | +68.63% | +53.89% | +9,952.34% | | mmap1_384_processes | BASE | 5,629,206 | 5,856,927 | 5,758,347 | 5,733,892 | 85,930 | | TEST | 12,053,514 | 13,635,555 | 12,966,975 | 13,283,450 | 606,325 | | % | +114.12% | +135.49% | +112.89% | +104.26% | +2,855.57% | | mmap1_512_processes | BASE | 6,959,199 | 6,996,383 | 6,975,912 | 6,974,353 | 15,446 | | TEST | 10,197,814 | 12,029,690 | 11,458,180 | 11,381,726 | 534,690 | | % | +46.54% | +71.94% | +64.25% | +63.19% | +3,361.67% | | tlb_flush2_384_threads | BASE | 2,953,477 | 3,021,464 | 3,003,512 | 3,014,264 | 25,525 | | TEST | 2,231,417 | 2,526,876 | 2,408,368 | 2,411,121 | 115,773 | | % | -24.45% | -16.37% | -19.81% | -20.01% | +353.55% | | tlb_flush2_512_threads | BASE | 2,499,486 | 2,542,966 | 2,520,278 | 2,530,049 | 17,161 | | TEST | 1,707,641 | 1,714,524 | 1,708,951 | 1,707,713 | 1,877 | | % | -31.68% | -32.58% | -32.19% | -32.50% | -89.06% | | mmap2_128_processes | BASE | 29,754,984 | 30,313,146 | 30,010,106 | 29,897,731 | 218,812 | | TEST | 9,688,640 | 9,750,688 | 9,710,137 | 9,696,830 | 23,428 | | % | -67.44% | -67.83% | -67.64% | -67.57% | -89.29% | | mmap2_256_processes | BASE | 7,483,929 | 7,532,461 | 7,491,876 | 7,489,398 | 11,134 | | TEST | 11,580,023 | 16,508,551 | 15,337,145 | 15,943,608 | 1,489,489 | | % | +54.73% | +119.17% | +104.72% | +112.88% | +13,276.75%| | mmap2_384_processes | BASE | 5,725,503 | 5,826,364 | 5,763,341 | 5,765,247 | 29,674 | | TEST | 11,682,353 | 13,720,566 | 12,269,665 | 11,776,228 | 877,060 | | % | +104.04% | +135.49% | +112.89% | +104.26% | +2,855.57% | | mmap2_512_processes | BASE | 6,959,199 | 6,996,383 | 6,975,912 | 6,974,353 | 15,446 | | TEST | 10,197,814 | 12,029,690 | 11,458,180 | 11,381,726 | 534,690 | | % | +46.54% | +71.94% | +64.25% | +63.19% | +3,361.67% |
