- Zoltan2 is a package in the Trilinos scientific computing toolkit/library that provides partitioning, load-balancing, and other combinatorial scientific computing features. It is fully parallel and has been used on supercomputers with hundreds of thousands of cores. It is the successor to the well-known Zoltan package, but has better support for new architectures (such as KNL, GPU) and tighter integration into Trilinos.
- The Combinatorial BLAS (CombBLAS) is an extensible distributed-memory parallel graph library offering a small but powerful set of linear algebra primitives specifically targeting graph analytics. It powers the HipMCL protein clustering software of the ExaBiome project and provides a foundation for the GraphBLAS standardization effort.
- Approximate-weight perfect matching (AWPM) code helps distributed sparse solvers such as SuperLU_dist and STRUMPACK to scale to larger concurrencies by eliminating serial bottlenecks. AWPM code is part of CombBLAS. Read more about AWPM here.
- KokkosKernels is a library for shared-memory parallel graph and (sparse & dense) matrix kernels. Although KokkosKernels is primarily funded and developed by SNL/ATDM, ExaGraph contributes to the graph algorithms, such as graph coloring.
