OPTIMIZATION OF THE GENERAL FORM MATRIX OPERATIONS FOR PENTIUM PRO PROCESSOR

Bruce Greer C., S.V. Kazakov, S.V. Sivolgin
VANT. Ser.: Mat. Mod. Fiz. Proc 1997. Вып.4. С. 3-10.

      Multilevel optimization of matrix float operations for Pentium Pro processor is described using one BLAS library program as an example. The upper levels of optimization increase the efficiency of using cache memory. The lower optimization level takes into account specific features of a microprocessor architecture. Performance plots for different algorithms are given.



PARALLELIZATION OF BLAS LIBRARY OF MAJOR LINEAR ALGEBRA OPERATIONS USING COMMON MEMORY

V.V. Lunev, D.M. Obuvalin, I.N. Orlov, S.V. Sivolgin
VANT. Ser.: Mat. Mod. Fiz. Proc 1997. Вып.4. С. 60-68.

      The results of works on creation of high-perfomance parallel BLAS library for systems with shared memory under OS Windows NT and UNIX are given. Parallel algorithms for this library programs are described and their efficiency for different processor numbers is estimated. The new formula for parallelization efficiency estimation is proposed.
