The D4M 3.0 release augments Accumulo support with Graphulo, and adds SciDB support. Graphulo enables graph algorithms in Accumulo with GraphBLAS kernels implemented as server-side iterators for Accumulo. Examples are included that demonstrate matrix multiply, breadth first search, Jaccard coefficient, k-Truss, and NMF (non-negative matrix factorization). SciDB is a popular database for multidimensional data with an array data model. D4M 3.0 includes a SciDB connector for fast ingest and query of data.
