warp.tile_scan_min_inclusive(

a: Tile[Scalar, tuple[int, ...]],

) → Tile[Scalar, tuple[int, ...]]

Kernel

Inclusive min scan across the tile.

This function cooperatively performs an inclusive min scan (cumulative minimum) across the tile.

param a:

The input tile. Must be a tile of type float32, int32, or uint32.

returns:

A new tile containing the inclusive min scan result.

Example:

@wp.kernel
def scan_example(input: wp.array(dtype=int)):
    t = wp.tile_load(input, shape=(4,))
    s = wp.tile_scan_min_inclusive(t)
    print(s)

input = wp.array([3, 1, 4, 2], dtype=int)
wp.launch_tiled(scan_example, dim=[1], inputs=[input], block_dim=16)

Prints:

[3, 1, 1, 1] = tile(shape=(4), storage=register)
