Correct me if I'm wrong, but I don't know of any current SIMD hardware that supports more than 64 bits of precision. An exception would be the x87 FPU (88 bits)

Correct me if I'm wrong, but I don't know of any current SIMD hardware that supports more than 64 bits of precision. An exception would be the x87 FPU (88 bits), but you can't do SIMD with that, so I don't think anybody interested in high-preformance linalg routines uses it.
- graycat 9y agoApparently my wish for 64 bit data, 128 bit products, and 128 bit addition is not reasonable on current hardware. So, I my wish will go unfulfilled.
