Parallel Basic Linear Algebra Subprograms (PBLAS) is an implementation of Level 2 and 3
BLAS intended for distributed memory architectures.
It provides a computational backbone for
ScaLAPACK The ScaLAPACK (or Scalable LAPACK) library includes a subset of LAPACK routines redesigned for distributed memory MIMD parallel computers. It is currently written in a Single-Program-Multiple-Data style using explicit message passing for interproce ...

LAPACK ("Linear Algebra Package") is a standard software library for numerical linear algebra. It provides routines for solving systems of linear equations and linear least squares, eigenvalue problems, and singular value decomposition. It al ...
. It depends on Level 1 sequential BLAS operations for local computation and
BLACS for communication between nodes.
