Next step I'm implementing matrix * matrix for large matrices with .NET 7 SIMD, starting to be 30-40% faster than Tensorflow, which is 😎 but I'm still 30-40% slower than MKL! 😅
Not that bad for a first try, but I will have to dig further if 1) I can optimize things further with some fancy AVX2 instructions, 2) If I can improve cache locality usage when going //

@logicalerror @aras @gekido the process creep completely suffocated me to be honest. I lost the will to do anything under it.

Friday fun playing around with #fortnite #uefn running round a scan the Natural History Museum (inspired by tweet below). This platform is insanely good!

@dneto @gfxstrand nearly did that in my youth - and if I had I would be blind now (had undiagnosed Keratoconus!). So glad I was too poor to afford it at the time!

@xoofx I think when I did it I used Robin Green's 2003 GDC talk approach, but turning log2 into log, and then using:

ln(x) = ln(2n × f )
= ln(2n )+ ln f
= nln2+ln f

I had to avoid a divide when I did this 10 years ago because it was slow on the GPU I was working on I remember!

@xoofx what did you use to do the range reduction? I vaguely remember the last time I did a low ULP variant of these years ago there were some tricks needed to get the input down to the range for the polynomial approximation!

FUN FACT about Verse now that UEFN is out: the floating point is not quite IEEE-754 double, but it's close. Specifically the functional logic programming part of Verse (which is to say, its foundation) requires a few axioms that IEEE floats don't satisfy, so the float semantics are slightly tweaked.

@MouseByTheSea thanks man!
