asc.experimental.asctile.device_print

asc.experimental.asctile.device_print(*values: Any, sep: str | None = None, end: str | None = None) → None

Print values during kernel execution on the device.

Outputs values to the device console. Strings are printed as-is, scalars are formatted by type, and tensors are dumped in full.

Parameters:

  • values – Values to print (strings, scalars, or tensors).

  • sep – Separator between values (default " ").

  • end – Line terminator (default "\n").

Note

Only active when debug=True is set in the JIT decorator. The built-in print() function dispatches to this function inside JIT kernels.

Examples

Print a mix of strings, scalars, and tensors:

@asctile.jit(debug=True)
def kernel():
    x = asctile.zeros([128], asctile.float32)
    asctile.device_print("block", asctile.block_idx(), "tensor", x)
