Eloisa The general consensus (I heard that as well from TACC staff) is that a KNL node is about as fast as a modern Xeon node. That agrees with what I measured on Cori.
The per-core performance is lower (maybe by a factor of two or three) because the cores are slower, but there are also more cores. -erik On Wed, Feb 22, 2017 at 5:53 PM, Haas, Roland <[email protected]> wrote: > Hello Eloisa, > > yup, widely off.
