[gmx-users] NVML does not come separate starting from Cuda 8.0

[Åke Sandgren]

CUDA 8.0.61_375_26 does not contain the actual NVML lib, only stubs.
And NVML is still separate from the CUDA package as far as i can see.

The libnvidia-ml.so in <CUDA>/lib64/stubs is much smaller than the
actual library.
