92.1 Introduction
A significant amount of execution time in complicated linear algebraic programs is known to be spent in a few low-level operations. Consequently, reducing the overall execution time of an application program leads to the problem of optimizing these low-level operations. Such low-level optimizations are highly machine-dependent and are a matter for specialists. A separation has, therefore, been made by the computational linear algebra community: On the one hand, highly efficient, machine-dependent building blocks of linear ...
