helion.language.atomic_and(target, index, value, sem='relaxed')[source]#

Atomically apply bitwise AND with value to target[index].

Parameters:

target (Tensor) – Tensor to update (integer/bool dtype).
index (list[object]) – Indices selecting elements to update. Can include tiles.
value (Tensor | int | bool) – Value(s) to AND with.
sem (str) – Memory ordering semantics. One of "relaxed", "acquire", "release", "acq_rel". Defaults to "relaxed".

Returns:

The previous value(s) stored at target[index] before the update.

Return type:

torch.Tensor
