Mojo function
max
max[val_type: DType, simd_width: Int, //](val: SIMD[val_type, simd_width]) -> SIMD[val_type, simd_width]
Computes the maximum value across all lanes in a warp.
This is a convenience wrapper around lane_group_max that operates on the entire warp. It performs a parallel reduction using warp shuffle operations to find the global maximum value across all lanes in the warp.
Parameters:
- val_type (
DType): The data type of the SIMD elements (e.g. float32, int32). - simd_width (
Int): The number of elements in the SIMD vector.
Args:
- val (
SIMD[val_type, simd_width]): The SIMD value to reduce. Each lane contributes its value to find the maximum.
Returns:
A SIMD value where all lanes contain the maximum value found across the entire warp.
