The reason why I would like to use ATLAS is that R FAQ said :
The savings can be appreciable: on a 2.6GHz P4 and a 1000 x 1000 matrix svd

is tuned to a particular chip we can't

saving 8 seconds of computation time is worth going through the ATLAS hassle?
For some of us, the 'hassle' is typing
$ sudo apt-get install atlas3-base
which gives you the low-hanging fruit of basic Atlas. Locally

hi everyone:
I have a Dell Server that has a Xeon processor, and I would like to use the
best ATLAS posted in the R website. I find that R has ATLAS for core2duo and
P4. I am not sure which one of these two is best suited for Xeon processor, or
is that neither of these two is good and I should
