dpctl.tensor.put returns incorrect result

[vlad-perevezentsev]

The code below works incorrectly in dpctl when dpctl.tensor.put needs to rewrite the duplicate index of an element with a different value

import dpctl.tensor as dpt

x = dpt.ones((5,))
ind = dpt.asarray([0, 0])

dpt.put(x, ind, [10, 20])
x
> usm_ndarray([10., 1., 1., 1., 1.])

import numpy
a = numpy.ones((5,))
numpy.put(a, [0, 0], [10, 20])
a
> array([20., 1., 1., 1., 1.])

put parallelizes assignments, and the present input results in race condition.

[oleksandr-pavlyk]

#1653 adds a docstring note for dpt.put warning of the race condition, and provides sample code for resolving it for 1D case.

This addition resolves this issue, which we intend to closed in a few days.

Closing this issue as resolved now that #1653 is in and #1384 is closed
