Orthogonal Factorizations: ScaLAPACK Computational Routines

This section describes the ScaLAPACK routines for the
factorization of matrices. Routines for the
factorization as well as for generalized
factorizations are also included. For the mathematical definition of the factorizations, see the respective LAPACK sections or refer to [SLUG].
"Computational Routines for Orthogonal Factorizations"
lists ScaLAPACK routines that perform orthogonal factorization of matrices.

Product and Performance Information


Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
