R is not supported under Cygwin, so that won't help, and is in any case unnecessary.
However, under Windows you can make use of ATLAS, and that is fully documented: we even provide versions of Rblas.dll for common chips. Part of my point was that a mobile Athlon will very likely need different tuning from your Athlon XP. The R developers have gone to considerable trouble to make ATLAS-tuned versions possible under Windows, so why ignore their efforts, Mr Borasky? On Wed, 23 Jul 2003, M.
