http://cas.ee.ic.ac.uk/people/gac1/pubs/FelixFPT17.pdf WebUsing shared memory (memory shared with CPU) isn't always going to be faster. Using a modern graphics card It would only be faster in the situation that the GPU/CPU are both performing oepratoins on the same data, and needed to share information with each-other, as memory wouldn't have to be copied from the card to the system and vice-versa. greenland exploration
