Hi All,
I am running p2pBandwidthLatencyTest on DGX-1, but it got failed as following:
/////////////////////////////
***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) in those cases.

Unidirectional P2P=Disabled Bandwidth Matrix (GB/s)
Cuda failure p2pBandwidthLatencyTest.cu:105: ‘unspecified launch failure’

If I run it in another system with only two P100, p2pBandwidthLatencyTest can run correctly, what’s the problem on my DGX-1 setting ?
