%global _description %{expand:
SuiteSparse:GraphBLAS is a complete implementation of the GraphBLAS
standard, which defines a set of sparse matrix operations on an
extended algebra of semirings using an almost unlimited variety of
operators and types. When applied to sparse adjacency matrices,
these algebraic operations are equivalent to computations on graphs.
GraphBLAS provides a powerful and expressive framework for creating
graph algorithms based on the elegant mathematics of sparse matrix
operations on a semiring.

SuiteSparse:GraphBLAS is used heavily in production. It appears as
the underlying graph engine in the RedisGraph database by Redis,
and as the built-in sparse matrix multiply in MATLAB R2021a, where
C=A*B is now up to 30x faster than in prior versions of MATLAB (on
my 20-core NVIDIA DGX Station).

The development of this package is supported by Intel, NVIDIA
(including the donation of the 20-core DGX Station), Redis,
MIT Lincoln Lab, MathWorks, IBM, and Julia Computing.}
