DescriptionThe ESSEX project is funded by the German DFG priority programme 1648 “Software for Exascale Computing” (SPPEXA). In 2016 it has entered is second funding phase, ESSEX-II.

ESSEX investigates programming concepts and numerical algorithms for scalable, efficient and robust iterative sparse matrix applications on exascale systems. Starting with successful blueprints and prototype solutions identified in ESSEX-I, the second phase project ESSEX-II aims at delivering a collection of broadly usable and scalable sparse eigenvalue solvers with high hardware efficiency for the computer architectures to come. ESSEX-II is now entering its third year, and we are working towards providing efficient and easily usable software components:

- GHOST, the General Hybrid Optimized Sparse Toolkit, a collection of highly parallel sparse linear algebra building blocks. Heterogeneous parallelism among CPUs, GPUs, and Xeon Phi ist fully supported. (Released)

- PHIST, the Pipelined Hybrid-Parallel Iterative Solver Toolkit. It provides general-purpose block Jacobi-Davidson Eigensolvers, Krylov methods, and a preconditioning interface. C, C++, Fortran 2003 and Python bindings are available, as well as mutiple backends (including GHOST). (Released)

- CRAFT, the Checkpoint/Restart and Automatic Fault Tolerance Library. It allows to efficiently add C/R and AFT functionality to C++ programs and supports shrinking and non-shrinking recovery as well as fully asynchronous checkpointing. (Released)

- RACE, the Recursive Adaptive Coloring Engine, provides efficient block multicoloring with performance superior to existing libraries. (Release in 2018 planned)

- ScaMaC, the Scalable Matrix Collection, allows the parallel generation of large sparse matrices from diverse applications fields in Quantum Physics. (Release in 2018 planned)
