The ATLAS (Automatically Tuned Linear Algebra Software) project is an ongoing
research effort focusing on applying empirical techniques in order to provide
portable performance. At present, it provides C and Fortran77 interfaces to
a portable, efficient BLAS implementation, as well as enhanced versions of a
few routines from LAPACK. To link with ATLAS shared libraries:
Serial (thread-safe) Fortran77 BLAS:
-lf77blas
Multi-threaded Fortran77 BLAS:
-lptf77blas
Serial (thread-safe) C BLAS:
-lcblas
Multi-threaded C BLAS:
-lptcblas
ATLAS-enhanced LAPACK, serial (thread-safe) interface:
-lalapack -lf77blas -lcblas
ATLAS-enhanced LAPACK, multi-threaded interface:
-lalapack -lptf77blas -lptcblas
===> The following configuration options are available for atlas-math-3.10.3_2,1:
ARCHDEF=off: Use a specified architectural default
DATA=on: Install tuning data and logs from the build
DOCS=on: Build and/or install documentation
TSC=off: If WALL_TIMER is enabled, use the TSC
WALL_TIMER=off: Use less robust timing with higher resolution
===> Use 'make config' to modify these settings
Backout to 3.5.5
a) newer version build fails like:
/usr/local/lib/libatlas.so: undefined reference to `ATL_dpKBmm_b1'
/usr/local/lib/libatlas.so: undefined reference to `ATL_dpKBmm_b0'
b) Define PORTEPOCH=1

build both threaded/non-threaded libraries
which introduced some kludge...
