Meaning of VM in OpenCL Programming Guide?

Hi,

I notice that the OpenCL Programming Guide changelog indicates that the table of memory behaviour has been updated to include whether or not "VM" is enabled.  I don't know what term this refers to, and it is not defined within the guide itself.  Virtual machine?  Virtual memory?  Something else?

Thanks.

I also confused about the VM, i think it should be Virtual Memory. But don't know how to disable and enable it.

I try all mem flags and can not achieve the peak bandwidth of data transfer, only about 3~6 GB/s.
