The (Ch) (I)mplementation of (N)umerical (G)raph (O)peratio(n)s is a GraphBLAS-like library written in Chapel. The docs, such as they are, are here

Chingon is (will be) designed to be similar to a Property Graph, in that the vertices will have attributes, but is not a database. It is more akin to igraph, Pregel or Giraph but, alas, considerably humbler in scope.

Please do consider contributing to the project. We can assist by being very nice and providing a delicious cup of coffee when in Pasadena, CA.

At the moment, we are only aware of one other GraphBLAS implementation. Some impressive work has been done at the Lawrence Berkeley National Lab by Azad and Buluc that has not (yet) been open-sourced. However, using Linear Algebra to tackle graph routines is a clear step forward in the intersection of Network analytics and High Performance Computing.

• Notably, that of Azad and Buluc
• Chingon uses NumSuch for the underlying statistical methods. It's inception is a response to this ticket and this earlier ticket
• Chingon is attempting to be compatible with Mason.
• Chingon uses the heck out of the CDO Project.
