It still should be beneficial from the point of view of core local caches.

Hi Andriy and Adam,
I did also the same thing as suggested.

My result of dgemm GotoBLAS performance was following.

Contrary to Adam's result, Hyper Threading makes the performance worse.

Do you know how gotoblas on Linux was obtained?
Was it built from source?
Has it come pre-packaged?
If so, can you find out details of its build configuration?
