[SciPy-user] singular value decomposition

Hi All,

I have code that needs to repeatedly perform an svd on a matrix (2304,  
2304) shape. It seems to take forever to do (I haven't timed it, but  
approximately two hours passed on the first trial (without completion)  
and I am now running a second to make sure nothing went wrong.

Is this because I am not linked to an optimized BLAS/LAPACK library or  
something else?

I have access to mkl. Is it possible to link an already installed  
scipy to mkl, or would I have to reinstall?
