Re: [Users] ET on KNL.

Hi all,

still on the KNL topic, I realize there was a question I ignored, and which perhaps is worth pursuing.

Eloisa: does Carpet report the vector size of the KNL as 8? From the wikipedia entry, I would expect that to be the case, but I think you mentioned to me that it was reporting 4.

That's correct. In my output I find:

=============================================================== INFO (Vectors): Using vector size 4 for architecture AVX (64-bit precision) ===============================================================

Is this not supposed to be so? And in this case, is there anything I can do about it?

Eloisa, are you using LoopControl?

Yes.
