def causal_conv1d_channel_last_fwd_gpu_no_bias[x_dtype: DType, weight_dtype: DType, output_dtype: DType, kNThreads: Int, kWidth: Int, kNElts: Int, x_LT: TensorLayout, weight_LT: TensorLayout, output_LT: TensorLayout](batch: Int, dim: Int, seqlen: Int, width: Int, x: TileTensor[x_dtype, x_LT, MutUntrackedOrigin], weight: TileTensor[weight_dtype, weight_LT, MutUntrackedOrigin], output: TileTensor[output_dtype, output_LT, MutUntrackedOrigin], x_batch_stride: UInt32, x_c_stride: UInt32, x_l_stride: UInt32, weight_c_stride: UInt32, weight_width_stride: UInt32, out_batch_stride: UInt32, out_c_stride: UInt32, out_l_stride: UInt32, silu_activation: Int8)

Optimized causal conv1d implementation for channel last data layout using SIMD operations (no bias).

Key optimizations:

  1. SIMD vectorization for input/output operations across channels
  2. Efficient memory access patterns with coalesced loads
  3. Vectorized weight loading and computation
  4. Optimized activation function with SIMD operations
  5. Better thread utilization and memory bandwidth usage
