Module Contents

tilelang.language.random.rng_init(seed, seq=None, off=0, generator='curandStatePhilox4_32_10_t')

Initialize CUDA curand random number generator state

參數:

  • seed (PrimExpr) -- Random seed value.

  • seq (PrimExpr) -- Sequence number for parallel random number generation.

  • off (PrimExpr) -- Offset number for parallel random number generation.

  • generator (StringImm) -- Set random generator. See https://docs.nvidia.com/cuda/curand/group__DEVICE.html

回傳:

state -- The random number generator state handle.
