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 On 08/31/2018 09:52 AM, Andrei Berceanu berceanu@runbox.com wrote: > 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 -- René Widera Phone: +49 351 260 3543 Institute of Radiation Physics http://www.hzdr.de/crp Helmholtz-Zentrum Dresden - Rossendorf (HZDR) Bautzner Landstr. 400 | 01328 Dresden | Germany Board of Directors: Prof. Dr. Dr. h. c.
