Dear All,
could anyone please tell me how to get a BLAS optimized to a particular machine and how install CLAPACK using this optimized BLAS.


thanks a lot

LInux or Windows?

For Linux, you can use ATLAS, GOTO BLAS, MKL or ACML. See http://en.wikipedia.org/wiki/Automatica ... a_Software
For WIndows, depending how you are developing, I would recommend ACML or MKL.

Hi there,

i tried compiling ATLAS with cygwin but i am getting following error:

can anyone help me with this:-

Is it that 64bit ATLAS compilation is not supported by cygwin, if so, what are my options?
