General Matrix Multiplication (GEMM) operation that computes C = A × B^T. This is a fundamental linear algebra operation used in neural networks for layer computations, attention mechanisms, and other matrix transformations. Variants:
  • FP16 GEMM: Uses 16-bit floating point (FP16) inputs for A and B matrices
  • FP8 GEMM: Uses 8-bit floating point (FP8) inputs for A and B matrices, with scaling factors to maintain numerical stability
Axes (3 dimensions):
  • M: variable
  • N, K: constant
Inputs (2 or 4 tensors):
  • A: [M, K]
  • B: [N, K]
  • Scaling factors for FP8 GEMM:
    • A_scale: [M]
    • B_scale: [N]
Outputs (1 tensor):
  • C: [M, N]
