nki.language.multiply#

nki.language.multiply(x, y, dtype=None)[source]#

Multiply the inputs, element-wise.

((Similar to numpy.multiply))

Warning

This API is experimental and may change in future releases.

Parameters:

  • x – a tile or a scalar value.

  • y – a tile or a scalar value.

  • dtype – (optional) data type to cast the output type to (see Supported Data Types for more information);

Returns:

a tile that has x * y, element-wise.

Examples:

import nki.language as nl

# nki.language.multiply -- element-wise multiplication of two tiles
a = nl.full((128, 512), 3.0, dtype=nl.float32, buffer=nl.sbuf)
b = nl.full((128, 512), 4.0, dtype=nl.float32, buffer=nl.sbuf)
c = nl.multiply(a, b)
expected = nl.full((128, 512), 12.0, dtype=nl.float32, buffer=nl.sbuf)
assert nl.equal(c, expected)

# nki.language.multiply -- scaling every element by a scalar
a = nl.full((128, 512), 3.0, dtype=nl.float32, buffer=nl.sbuf)
c = nl.multiply(a, 4.0)
expected = nl.full((128, 512), 12.0, dtype=nl.float32, buffer=nl.sbuf)
assert nl.equal(c, expected)
