Thanks to petri33 who send me nicely its own binaries, my GTX 1080 rocks now !
It takes around 4 minutes to complete a wu (blc or classic :)

Thanks for your help :)


Thank you for volunteering to test a Linux version.

And additional you could try to speed up your CPU a little by using MBv8_8.05r3345_avx_linux64_CPU.7z from lunatics.

Is there some similar Windows binary to test, I would gladly volunteer... ;)

Message 1812813 - Posted: 26 Aug 2016, 19:25:43 UTC - in response to Message 1812491.  

I'm using currently SSE4.2 . What is the difference between SSE4.2 and AVX ?

Maybe a little help page from lunatics website would be helpful ;)

Start reading from https://en.wikipedia.org/wiki/SIMD and use the included links to SSE4.x and AVX to gain the knowledge you want. (Maybe even available in your mother language)

From lunatics side : AVX is more advanced vector extension and allows more data parallelism than SSE4.2, so it can crunch faster if the hardware supports it.

Compare the SSE4.2 runtimes of your Ci7 6700 @ 4GHz to the AVX runtimes of my Ci5 6500T @2.8GHz (running on 3 of 4 cores) to get the idea how much faster it could be.

With the Windows applications, huge, as we don't actually have a SSE4.2 application- it reverts back to SSSE3 (which is still pretty good). However the Lunatics Windows AVX application performs much better than the stock AVX application, which is better than the SSSE3 application.

Raistmer has stated that lunatics AVX is 10% faster than stock AVX, he's the developer so me thinks he knows.

ok thanks...I will switch to the avx binary so
Thanks for the advice :)
