Mixed-Precision Operators
The practice of mixing different precisions such as FP16/BF16 and FP32 within a single forward computation. Compute-intensive operators run at lower precision to improve throughput, while numerically sensitive stages retain FP32 to prevent error accumulation.
Timeline (last 90 days)
The core technologies of this optimization scheme are dynamic VRAM paging and a new generation of mixed-precision operators.
Mixed-precision operators mean mixing FP16/BF16 with FP32 within the same forward computation, using low precision for compute-intensive operators to improve throughput and retaining FP32 in numerically sensitive parts to avoid overflow and the accumulation of rounding errors.
The benefit of mixed-precision operators depends on whether the graphics card supports the corresponding low-precision instructions; older cards may not achieve the same acceleration.
