- what does setting
torch.backends.cudnn.deterministic
toTrue
orFalse
do?
On my GTX1080, when I run waveglow, the speed is dramatically slower if I turn torch.backends.cudnn.deterministic = False
compared to True
. However, the speed is not changed on some GPUs whether I turn this on or off – ex. GTX 1050Ti’s speed of running waveglow as not impacted.
So what does torch.backends.cudnn.deterministic
do? and why does it impact speed on some GPUs and not others?
- What does
torch.backends.cudnn.benchmark
do? and what impact on speed does it have?
