"BAR1 Memory Usage
BAR1 is used to map the FB (device memory) so that it can be directly accessed by the CPU or by 3rd
party devices (peer-to-peer on the PCIe bus)."
but i don’t get this one… what’s the thing with directly acces by the CPU?
Technically this might be possible but OEMs won’t support different Tesla boards in the same server. Therefore you should use the same boards for a specific server.
