I am facing issue running applications with NVBit that use cudaDeviceEnablePeerAccess in the program. nvbit tools such as instr_count give cudaErrorPeerAccessUnsupported error. One such example is simpleP2P in cuda samples (cuda/samples/0_Simple/simpleP2P).

simpleP2P runs successfully without NVBit.

I am running nvbit on nvidia DGX-2 with cuda driver version 418.116.00

Tried to repro this on latest version of NVBit, but all run as expected on DGX-2.
Closing for now, please reopen with more info if this issue still exists.
