cuda.tile.sqrt#

cuda.tile.sqrt(x, /, *, rounding_mode=None, flush_to_zero=False)#

Perform sqrt on a tile.

Parameters:

  • x (Tile)

  • rounding_mode (RoundingMode) – The rounding mode for the operation, only supported for float types, default is RoundingMode.RN when applicable.

  • flush_to_zero (const bool) – If True, flushes subnormal inputs and results to sign-preserving zero, default is False.

Return type:

Tile

Examples

tx = ct.full((4,), 4.0, dtype=ct.float32)
print(f"{ct.sqrt(tx):.1f}")

import cuda.tile as ct
import torch

@ct.kernel
def kernel():
    tx = ct.full((4,), 4.0, dtype=ct.float32)
    print(f"{ct.sqrt(tx):.1f}")


torch.cuda.init()
ct.launch(torch.cuda.current_stream(), (1,), kernel, ())
torch.cuda.synchronize()

Output

[2.0, 2.0, 2.0, 2.0]
