[Pw_forum] ATOMIC_POSISTIONS nonexistent when using space groups

[Gunnar Palsson]

Filippo,

I would be very grateful if you could send me the files to swap! I think you are probably right that it is a curiosity exercise but I’d like to take a whack at it. There might be room in our budget to go for a card like the GTC 1080 down the road, which looks very cool indeed.

Best regards,
Gunnar

Future NVIDIA gaming cards based on Pascal architecture will have a huge single precision perfemance (> 5TFlops per card)  and a decent double precision one as well (~1.4 TFlops). All of this needs to be assessed and tested but it is going to be substantially better than Maxwell-based cards for codes that need double precision.
