====== DBCSR - A Sparse Matrix Library ======

{{ :dbcsr_logo.png?nolink&300 |}}


DBCSR is a standalone sparse matrix library designed to efficiently perform sparse matrix matrix multiplication, among other operations. It is MPI and OpenMP parallel, and can exploit accelerators. 

It is used in[[ http://www.cp2k.org/ | CP2K]], where it provides core functionality for [[ doi>10.1021/ct200897x | linear scaling electronic structure theory]]. A general overview of the library [[ doi>10.1016/j.parco.2014.03.012 | has been published]]. A discussion of recent developments, in particular GPU work, [[ doi>10.1002/9781118670712.ch8 | has appeared as a chapter]] in 'Electronic Structure Calculations on Graphics Processing Units', John Wiley and Sons, ISBN 9781118661789, and is available as a {{ :gpu_book_chapter_submitted.pdf |preprint }}. The use of one-sided MPI and a 2.5D algorithm to reduce communication is shown to be effective for sparse matrix matrix multiplication in [[https://arxiv.org/abs/1705.10218 | this manuscript]].

DBCSR is made available for integration in other projects, see the [[https://github.com/cp2k/dbcsr|github webpage]].
