sse2 vs avx

Posted 1 Nov 2019 by noxcivi If you show me an example that a Ryzen 3000's advantage is less than 3% for using avx/fma over sse2, I will be quiet on this topic forever. My guess was that it would be much more and that is why I wanted to mention the missing options for the users. |

Posted 30 Oct 2019 by noxcivi I have to dig up this topic. This project is very limited in allowing the users to decice which app will run. It is all decided by whatever algorithm. Now, I have a new CPU that would be faster with the avx version but my machine will not get that version, because the old CPU was slower on avx. The avx-FLOPS for my machine are outdated, but cannot become refreshed as I will not get avx tasks. This is a loop I cannot escape on my own. Using an app_info.xml is a shitty workaround because it creates a new "generic local app"-profile on the servers statistics. I'd like to use the avx version the official way. |

Posted 30 May 2018 by noxcivi An issue on my end is a pretty high error rate on sse2 tasks with my ryzen pc. avx runs flawless now. |
