%description
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 interprocessor communication.
It assumes matrices are laid out in a two-dimensional block cyclic
decomposition.

Like LAPACK, the ScaLAPACK routines are based on block-partitioned
algorithms in order to minimize the frequency of data movement
between different levels of the memory hierarchy. (For such machines,
the memory hierarchy includes the off-processor memory of other
processors, in addition to the hierarchy of registers, cache, and
local memory on each processor.) The fundamental building blocks
of the ScaLAPACK library are distributed memory versions (PBLAS)
of the Level 1, 2 and 3 BLAS, and a set of Basic Linear Algebra
Communication Subprograms (BLACS) for communication tasks that arise
frequently in parallel linear algebra computations. In the ScaLAPACK
routines, all interprocessor communication occurs within the PBLAS
and the BLACS. One of the design goals of ScaLAPACK was to have the
ScaLAPACK routines resemble their LAPACK equivalents as much as
possible.
