[Numpy-discussion] Atlas and dual core

[Keith Goodman]

Is there much speed to be gained by compiling atlas for a dual core system?

I'm running Ubuntu on a Macbook. It's the first time I've had a dual
core system.

My one line benchmark shows that the Macbook is slow compared to my
(old) desktop.

>> t1=time.time();x=randn(500,1000);x =
x*x.T;a,b=linalg.eigh(x);t2=time.time();print t2-t1
1.31429600716

My desktop is less than half of that.
