Any chances to get optimizations included in the app ? WUs seem so slow ...


Yep. I will try to do some optimizations in free time.

FIrst I have to look in new source(models).

AVX2 version.

Download:

You should get up to ~30% speedup depends on cpu type, on new Intel Skylake even more.


My laptop trashed all the units using this one, I reverted to the old one and it is fine again.


^ Same result. On W7 i5 2400



AVX2 is available only on i3/i5/i7/xeon 4th gen or newer processors. So only i3/i5/i7 4xxx+ or Xeon v3+

Last month was very busy for me. I hadn't time to finish what I started in August.

Yesterday I finally finished rewrote model to perform from SSE2/SSE3 instructions and replaced Intel SVML functions with open source replacement (Logarithm form GROMACS 5.1, exponential from Herumi fmath). This is almost the same code as used by Crunch3r, exp is faster than Intel SVML, log is almost as fast as intel.


All this gives about 30% speed improvement over 1.4.1
