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.
Roland, Erik,
thanks for the tips. I will try the stampede configuration (the machine I am trying this on is CINECA's Marconi, for the record) and see if it improves things.
