Multiplication and shared memory are totally unrelated.

You need to give better explanation.

Shared memory does not have any relationship with 64bit multiplication.

In java Long is 64 bit. I don't see the issue of implementing anyway.

Memory can be shared in couple of ways. Read the following stackoverflow[^] for better understanding.

And if you have exclusive problem sharing a 64 bit memory then you may need to take special look on your data type
