Optimization guide memory allocation

I'm trying to implement the guide's suggestions for memory allocation, p 1-9. Can't understand what it means, though :-(

In the CL_MEM_ALLOC_HOST_PTR, without VM case it states zero copy between (PC's?) CPU and what?

In my case I need it for transfers between my PC's CPU and my card's GPU where i run the kernel.  Is that the right case?

No speed improvements, and wrong results due to synchronization issues.

What is the difference between that and the default case without any flags?
