In fairness, "SIMD support" is not exactly "the compiler can reduce code to AVX instructions" but more like "you can now write non-portable custom assembly-like code to make your code faster".
- smegsicle 3y agobut i assume a somewhat nicer interface than the internal VOP intrinsic stuff that sbcl has always had
- rice7th 3y agoStill better than no SIMD at all imo
- koito17 3y agoYup. I used to use Clozure CL all the time, but since the code I write tends to involve lots of number crunching, SB-SIMD and Loopus are indispensible. Even before SB-SIMD, SBCL has always seemed like the best Common Lisp implementation for any arithmetic. Or at least this seems to be case when you benchmark CCL against it :)
- ravi-delia 3y agoThat's what I mean by "willing to hack"! Getting the compiler to use SIMD instructions is actually pretty easy- you just specify where to use them and let it handle them. Then you pinky promise that your array really is made of floats and turn safety off.
