  • sb-simd

    Discontinued A convenient SIMD interface for SBCL.

    • For SBCL-specific, Marco and Bela have put in a ton of work at sb-simd - may be the OP finds the relevant simd interface there!

  • bmas

    Basic Mathematical Subprograms - SIMD operations on strided vectors of floats, doubles, u/int/64/32/16/8

    • (Shameless plug) I recently added AVX2 256-bit simd based integer copy instructions to BMAS - and this is accessible through bmas (extremely thankful to C2FFI!) And I'm wanting to try memcpy to see if that gets any further benefit, hoping to try some time during the week.
