Mojo function

min

min[type: DType, width: Int, //, *, block_size: Int, broadcast: Bool = True](val: SIMD[type, width]) -> SIMD[type, width]

Computes the minimum value across all threads in a block.

Performs a parallel reduction using warp-level operations and shared memory to find the global minimum across all threads in the block.

Parameters:

type (DType): The data type of the SIMD elements.
width (Int): The number of elements in each SIMD vector.
block_size (Int): The total number of threads in the block.
broadcast (Bool): If True, the final minimum is broadcast to all threads in the block. If False, only the first thread will have the complete min.

Args:

val (SIMD[type, width]): The SIMD value to reduce. Each thread contributes its value to find the minimum.

Returns:

If broadcast is True, each thread in the block will receive the minimum value across the entire block. Otherwise, only the first thread will have the complete result.
