Correct--the note on the git commit even says so, although I don't expect
users to see that sort of thing. Once 2080Ti is in our hands we'll have it
tested and posted. Ross will be running some additional benchmarks today
so we can add official 2080 numbers, and the most important thing I can
think of is pretty easy to change (one line), so we may know sooner rather
than later how much performance tuning can benefit us on this peculiar
architecture. (And I do mean peculiar--even NVIDIA doesn't see this as the
new normal).
TBH, if you are considering a new GPU cluster, I would look seriously at
the Titan-V. Full double-precision calculations, $3000 per GPU. Multi-GPU
applications exist, but the peak performance point for almost anything is
going to be single GPU, and if you have people looking to do their own
custom coding then doing everything in double precision will take off one
layer of complexity. Four times as expensive as GTX-1080Ti (if you can
still get those), 1.75x the performance. It's a trade-off between time and
money.
