Books

Graph Algorithms in the Language of Linear Algebra (SIAM, 2011) by Jeremy Kepner and John R. Gilbert
 This is the best reference on the topic of linear algebrabased graph processing. However, note that GraphBLAS effort was not yet started when this book was written. Therefore, there are some differences between the notation of GraphBLAS documents and the one used in this book.

Mathematics of Big Data: Spreadsheets, Databases, Matrices, and Graphs (MIT Press, 2018) by Jeremy Kepner and Hayden Jananthan
 An updated version of paper Mathematical Foundations of the GraphBLAS is reprinted in this book (Chapter 6, p81113)
 This book is currently the latest detailed reference on semiringbased computations, including graph algorithms. It also covers many other topics such as associative arrays. The book is not intended to be a GraphBLAS reference, but it can be used for providing a background in linear algebra (see e.g. Chapter 8, “Visualizing the Algebra of Associative Arrays”).

Path Problems in Networks (Morgan & Claypool Publishers, 2010) by John S. Baras and George Theodorakopoulos.
 This book is about the algebraic path problem – a semiringbased generalization of shortest path problem. The mathematical foundations of semiringbased graph analysis are described. Basic ideas to create new semirings to solve new problems are described.
 The section 3.1 “Alternative viewpoints: paths and matrices” (p1719) provides a matrixbased framework for the algebraic path problem which is highly relevant to GraphBLAS.
 The table on pages 5859 contains 29 different semirings and respective applied problems.

Wrappers
 Python wrappers:

pygraphblas: a Python wrapper for SuiteSparse:GraphBLAS aiming to provide a Pythonic AP

grblas: a Python wrapper for SuiteSparse:GraphBLAS with a new highlevel syntax that provides a 1:1 mapping between the C API and Python
 This library and all dependencies can be installed with conda for OS X and Linux

daskgrblas: mirrors the grblas API and uses dask for outofcore or distributed computation

PyGB: a Python wrapper for GBTL

SuiteSparseGraphBLAS.jl: a Julia wrapper for SuiteSparse:GraphBLAS

rustgraphblas: a Rust wrapper

graphblasjavanative: a Java wrapper
 MATLAB wrapper: builtin for SuiteSparse:GraphBLAS
