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
|
|
portably efficient BLAS implementation, as well as a few routines from LAPACK.
|
|
|
|
PLEASE REBUILD YOUR KERNEL WITH
|
|
options CPU_ENABLE_SSE
|
|
TO ENABLE SSE1/SSE2 SUPPORT BEFORE MAKING ATLAS!
|
|
IT SIGNIFICANTLY IMPROVES PERFORMANCE.
|
|
|
|
If you use blas, you can simply change flags when linking,
|
|
from -lblas to -lf77blas -latlas -lblas (order is important)
|
|
get a significantly performance increase.
|
|
|
|
LAPACK subroutines are partially implemented.
|
|
You change from -llapack to -lalapack to get better performance.
