Automatically Tuned Linear Algebra Software (ATLAS)
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. If you want to link software to ATLAS rather than the standard BLAS, simply use -lf77blas -latlas (order is important), or -lptf77blas -latlas for the threaded library (which is primarily useful on SMP machines), in place of the usual -lblas. Corresponding pure C versions of the ATLAS libraries are also included, in libcblas and libptcblas. The ATLAS-enhanced LAPACK routines are also provided. To link software with this library instead of the standard LAPACK, use -L/usr/local/lib/gcc-4.2.3 -L/usr/local/lib/gcc-4.2.3/gcc/i386-portbld-freebsd7.0/4.2.3 -lalapack -lf77blas -lcblas -latlas -lgfortranbegin -lgfortran -lm, or -L/usr/local/lib/gcc-4.2.3 -L/usr/local/lib/gcc-4.2.3/gcc/i386-portbld-freebsd7.0/4.2.3 -lalapack_r -lptf77blas -lptcblas -latlas -lgfortranbegin -lgfortran -lm for the threaded library, in place of the usual -llapack. Note that -L/usr/local/lib/gcc-4.2.3 -L/usr/local/lib/gcc-4.2.3/gcc/i386-portbld-freebsd7.0/4.2.3 depends on your environment.
