PBLAS Routines

The PBLAS routines perform operations with distributed vectors and matrices.

  • PBLAS Level 1 Routines perform operations of both addition and reduction on vectors of data. Typical operations include scaling and dot products.

  • PBLAS Level 2 Routines perform distributed matrix-vector operations, such as matrix-vector multiplication, rank-1 and rank-2 matrix updates, and solution of triangular systems.

  • PBLAS Level 3 Routines perform distributed matrix-matrix operations, such as matrix-matrix multiplication, rank-k update, and solution of triangular systems.

Intel MKL provides the PBLAS routines with interface similar to the interface used in the Netlib PBLAS (part of the ScaLAPACK package, see http://www.netlib.org/scalapack/html/pblas_qref.html).

Optimization Notice

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.
