[P2P (Peer-to-Peer) GPU Bandwidth Latency Test]
|
||
|
|
Device: 0, NVIDIA H100 PCIe, pciBusID: c1, pciDeviceID: 0, pciDomainID:0
|
||
|
|
|
||
|
|
***NOTE: In case a device doesn't have P2P access to other one, it falls back to normal memcopy procedure.
|
||
|
|
So you can see lesser Bandwidth (GB/s) and unstable Latency (us) in those cases.
