One of the largest stumbling blocks to generate a significant increase in the performances of the GPGPU, and more generally with calculations shared between the main frame and the graphics processor is related to the fact that it is necessary to transfer the data from the main memory of the machine to that of the graphics card where they will be treated and then the data is transferred in the opposite direction so that it can be used.Intel, which continues to work on its Larrabee project decided to solve this problem with an innovative technique. They will create a virtual memory shared between the two elements and in which each unit will be able to pick according to its needs without having to pass through the PCI-Express bus, a true bottle neck. We do not know yet the details of the procedure, but it seems very promising on paper, we are waiting to see what Larrabee will give us, however it continues to be delayed. As a reminder, Intel wants to go an opposite direction to that of
