The GraphBLAS 3.0 Project

The GraphBLAS C API is mature with an updated specification (version 2.1) and a compliant implementation (SuiteSparse GraphBLAS). We are now focused on GraphBLAS 3.0; the next major GraphBLAS revision. Potential changes include: (1) a separate math spec to make new language bindings easier to write, (2) better support for user-defined types, rank promotion, and enhanced non-blocking execution, (3) expanded scope of GraphBLAS to address a wider range of applications, and (4) support for complex heterogeneous and distributed systems.
