Hi Luc, the Blas library in LAPACK is a reference implementation. It is not optimized and sucks big time : it's just a model of the functions performed by the library. The performance of ATLAS is much (MUCH) better. I would advise you to find the time to look into it :-)) Cheers. -- Patrick Geoffray --------------------------------------------------------------- | Myricom Inc | University of Tennessee - CS Dept | | 325 N Santa Anita Ave. | Suite 203, 1122 Volunteer Blvd. | | Arcadia, CA 91006 | Knoxville, TN 37996-3450 | | (626) 821-5555 | Tel/Fax : (865) 974-0482 | ---------------------------------------------------------------
