https://bugs.documentfoundation.org/show_bug.cgi?id=142307 --- Comment #8 from dante19031...@gmail.com --- > Yeah, I just want to know info like: > > "I have a spreadsheet with 1 million cells with data and 100 formulas > > It took 1 min for recalculating before > It take 10 sec for recalculating after" That depends of the computer, for mine (3*10^6 terms): Time for sum with NONE: 0.002667 s (default on ARM) Time for sum with AVX: 0.001426 s (new) Time for sum with SSE2: 0.001914 s (original) And I can't tell you about AVX512. But can't give you much more info. This kind of thing will work on auto generated calc sheets with insane amounts of data. So expect an improvement of ~ * 1.4 on the sum plus the time spended on the interpreter. -- You are receiving this mail because: You are the assignee for the bug.

I think it would be interesting to know how much has the > calculation accelerated by using AVX The test can be found in this file: /core/sc/qa/unit/functions_statistical.cxx (It is not yet on opengrok, give it 48 hours) The original code is the SSE2 version. So the new and old versions are tested. But I don't believe this is what you are asking for. However here you have a performance test (very basic): https://gerrit.libreoffice.org/c/core/+/121095/2 However printf does not seem to work. And it may fail due to statistical fluctuations. Particularly on server technology. So can not be merged. -- You are receiving this mail because: You are the assignee for the bug.

https://bugs.documentfoundation.org/show_bug.cgi?id=142307 --- Comment #3 from dante19031...@gmail.com --- Right now I'm working over here: https://gerrit.libreoffice.org/c/core/+/115675 I was able to implement Neumanier for SSE2. Now you're test sheet gives correct output. AVX512 for now crashes, but is on it's way. We are using the methods in this order: If AVX512 is available use it. If not try with SSE2. If not continue with just unrolled loop. -- You are receiving this mail because: You are the assignee for the bug.___ Libreoffice-bugs mailing list Libreoffice-bugs@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/libreoffice-bugs
