Hi Ross and Chris,
Good news!
Is there any theoretical possibility one to obtain access to this development version for test purpose?
Regards,
Filip

The development version of Amber14 currently does not support P2P for
CUDA_VISIBLE_DEVICES="0,1" or
CUDA_VISIBLE_DEVICES="2,3".
it gives the error:
cudaDeviceEnablePeerAccess all CUDA-capable devices are busy or unavailable
Work-around:
To get around this issue, root must disable exclusive compute mode on the
relevant cards using "nvidia-smi -c 0"
[root.compute-0-1 ~]# nvidia-smi -c 0
Set compute mode to DEFAULT for GPU 0000:02:00.0.
Set
compute mode to DEFAULT for GPU 0000:03:00.0.
Set compute mode to DEFAULT for GPU 0000:83:00.0.
Set compute mode to DEFAULT for GPU 0000:84:00.0.
And now....

Ross has submitted this bug to NVIDIA, but this work-around will suffice in
the interim.
Happy simulating!
