Can I get ATLAS in rpm or .deb or some other format?
Our only supported format is a compressed tarfile. If you really feel the need for .rpm or .deb versions, other parties (eg, Debian, SuSE) provide them (note that we can’t answer questions on ATLAS installed in this way, however, since we don’t know much about them). ATLAS provided by third parties may not be as up-to-date, or may run slower than compiled ATLAS (eg., some companies compile only a couple of x86 libraries, so that they would use the same library for the P4 and P4E chips, even though ATLAS should tune itself separately to all the x86 variants for maximal performance).
