Thank you René.
So are the 64 K80 boards on Hypnos 64 cards (with 2 GPUs each), or 64 GPUs (32 actual cards)?

Best,
Andrei

Hi Andrei,

I have currently no performance data for the P100 available but if I
remember correct one P100 is two times faster than one k80 (with on K80
I mean one card with two sockets).
For V100 I have currently no numbers in my head but due to improvements
of the shared memory atomics a V100 should be faster than a P100.

best regards,

René
