Dear All,
does anyone saw any instructions or may be just a ready makefile for compilation Atlas for further using with lf95?
Or may be you have an information about comparison of lapackmt/blasmt Laney's libraries versus Atlas for Intel/AMD processors?

my experience on compilation is currently next:
1. compiling Atlas with
F77 = /usr/bin/g77
F77FLAGS = -fomit-frame-pointer -O
gives good results for futher using with g77, but complains about undefined references if I try to compile any fortran 90/95 code with lf95
2. compiling Atlas with
F77=lf95
F77FLAGS= -O
gives realy bad perfomance comparing to prebuilt blasmt/lapackmt
3. compiling Atlas with
F77=lf95
F77FLAGS= --o2 --warn --quiet --tp4 --prefetch --ntrace
later complains about undefined references if I try to compile f90 code with lf95
For all compilation I used built complete LAPACK library as described on http://math-atlas.sourceforge.net/errata.html#completelp
gcc version: 3.3.1 on SuSE Linux
Linking for f90 codes:
-latlaslapack -lf77blas -lcblas -latlas
Architecture: Athlon XP 2800+ 2.08GHz/333MHz (Barton) with 512Kb L2 cache
Any help/suggestions would be welcome.
