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 //

Storyteller is an amazing little game. Not long, but a lovely concept and I had a lot of fun playing! https://store.steampowered.com/app/1624540/Storyteller/

It’s been years in the making and we’re finally ready to show the world: don’t miss Yeoul’s EuroLLVM keynote, “-fbounds-safety: enforcing bounds safety for production C code”! https://discourse.llvm.org/t/the-2023-eurollvm-program/69514

@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!

@jupiter it's amazing how popular the skookum script derived concurrency model has been with our alpha users and the internal teams that made the experiences in Verse - I'm glad you liked it!

@xoofx there was a question in the Q&A about it - but basically we've got a VM, GC, and transactional memory!

@daniel_collin glad to see this finally public man!

I think this slide is important for the many people who asked what the future direction of the Verse language is - we're going to bring it to UE!

The team did a bit of a deeper dive into the Verse language specifically in a later session - can check out the recording here https://www.youtube.com/live/teTroOAGZjM?feature=share&t=22503

@gabrielesvelto that’s still 50-60 million cars on the road. I agree the demand for cars could be down, but there is zero way for rural communities to exist without cars, and trust me I’d rather be on a train!

@gabrielesvelto I get your ICE comments - but cars in general? In a remote community like mine there are zero alternatives to cars!

Dependent Types mentioned in a GDC talk! Never thought I’d see the day 😀
