# ScaLAPACK Routines

This chapter describes the Intel® Math Kernel Library implementation of routines from the ScaLAPACK package for distributed-memory architectures. Routines are supported for both real and complex dense and band matrices to perform the tasks of solving systems of linear equations, solving linear least-squares problems, eigenvalue and singular value problems, as well as performing a number of related computational tasks. All routines are available in both single precision and double precision.

### Note

ScaLAPACK routines are provided only with Intel® MKL versions for Linux* and Windows* OSs.

Sections in this chapter include descriptions of ScaLAPACK computational routines that perform distinct computational tasks, as well as driver routines for solving standard types of problems in one call.

Generally, ScaLAPACK runs on a network of computers using MPI as a message-passing layer and a set of prebuilt communication subprograms (BLACS), as well as a set of BLAS optimized for the target architecture. Intel MKL version of ScaLAPACK is optimized for Intel® processors. For the detailed system and environment requirements see Intel® MKL Release Notes and Intel® MKL User's Guide.
