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

Dear all,

In you experience, how does PIConGPU performance vary across different Tesla cards, such as the K80, P100 and V100?

Is it fair to say, for instance, that one P100 is equivalent to two K80s?

Best regards,
Andrei
