Expand description
MXFP (OCP Microscaling) quantization descriptor (scheme tag 0x05).
A block quantization format standardised by the Open Compute Project
Microscaling specification (OCP MX v1.0). Each contiguous block of elements
along a chosen axis shares a single float8_e8m0 exponent-only scale stored
in a dedicated buffer. Unlike per-block affine, MXFP requires exact
divisibility — partial trailing blocks are not permitted.
See docs/spec/quantization/mxfp.md for the normative definition.
