// This file contains tests for sparse MMA (mma.sp.sync) operations with KIND variants.
|
|
// The kind::f8f6f4 variant was introduced in PTX ISA 8.7 for sm_90+ architectures.
|
|
//
|
|
// Based on PTX ISA documentation:
|
|
// https://docs.nvidia.com/cuda/parallel-thread-execution/#warp-level-matrix-instructions-for-sparse-mma
|
|
//
|
|
// KIND::F8F6F4 enables:
|
|
// - Additional FP8 types: e3m2, e2m3, e2m1
|
|
// - F16 accumulator for m16n8k64 FP8 operations
|
|
// - Mixed-precision FP8 computations
|
|
//
|
|
// Requirements:
|
|
// - ONLY works with ordered metadata (sp::ordered_metadata)
|
|
// - ONLY for shape m16n8k64
|
|
// - ONLY for FP8 types (not integers or other floats)
