Intel® oneAPI

Math Kernel Library

implements 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.

Intel® oneAPI Math Kernel Library

ScaLAPACK routines are written in FORTRAN 77 with exception of a few utility routines written in C to exploit the IEEE arithmetic. All routines are available in all precision types: single precision, double precision, complexm, and double complex precision. See the

mkl_scalapack.h

header file for C declarations of ScaLAPACK routines.

See descriptions of ScaLAPACK computational routines that perform distinct computational tasks, as well as driver routinesfor solving standard types of problems in one call. Additionally,

Intel® oneAPI

Math Kernel Library

implements ScaLAPACKAuxiliary Routines, Utility Functions and Routines, and Matrix Redistribution/Copy Routines. The library includes routines for both real and complex data.

The

<install_directory>

/examples/scalapackf

directory contains sample code demonstrating the use of ScaLAPACK routines.

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.
