Update/dpctl memcpy async

[reazulhoque]

This updates API changes in dpctl for memcpy. IntelPython/dpctl#557

[oleksandr-pavlyk]

This will presently make it break, since no such package is yet available on the channels.

@oleksandr-pavlyk
If API changed then dpctl version should be 0.10.0 (dev0).
0.9.1 is a patch version.
Right?

[oleksandr-pavlyk]

To play nice with multi-versioning on Linux - yes.

[PokhodenkoSA]

Suggested change

	- dpctl >=0.9.1.dev*
	- dpctl >=0.10.0*

[oleksandr-pavlyk]

Wouldn't it be better to create a function:

def synchronous_memcpy(q, dst, src, size):
     event = dpctl_functions.queue_memcpy(q, dst, src, size)
     dpctl_functions.event_wait(event)
     dpctl_functions.event_delete(event)

and use it throughout, perhaps even in dpctl_functions module?

[oleksandr-pavlyk]

Opinions?

[PokhodenkoSA]

About dpctl API I would like to propose to try to avoid breaking changes:

def queue_memcpy(..., wait=True): 
    ...
    if (wait):
        dpctl_functions.event_wait(event)
        dpctl_functions.event_delete(event)
        return None
    return event

def queue_memcpy_async(...):
    return queue_memcpy(..., wait=False)

[PokhodenkoSA]

@reazulhoque It is not necessary to use dev here. Just >=0.9.1*

Suggested change

	- dpctl >=0.9.1.dev*
	- dpctl >=0.9.1*

[PokhodenkoSA]

Suggested change

	- dpctl >=0.9.1.dev*
	- dpctl >=0.10.0*

[PokhodenkoSA]

Waiting for dpctl 0.10.0dev0 upload to channels.

[PokhodenkoSA]

I think we can merge it.
