Hi,
never tested. I would expect it to work, however, it will be slow(er).
Basically, the physical memory address space must be shared. In 64-bit systems this should be possible.
If you get it work: please feel free to share your experience :-)

best,
Ralf

Thank you for your answer. "Basically, the physical memory address space must be shared" is a correct statement. Currently, I am conducting an experiment using the GPUDev library in DPDK.
