TL;DR of the article, generated automatically.

Paper on mantissa bits needed for fixed-point double-precision matrix multiply.

  • Proof: 53 bits plus a span capacity and constant keep the classic bound.
  • Tests: cuBLAS on B200 gets grade A on Test 2c, double at widest ranges.
  • Caveat: bound holds in exact arithmetic, on every input tested.
