Trilinos is a collection of open source software libraries, called ''packages'', intended to be used as building blocks for the development of scientific applications. The word "Trilinos" is Greek and conveys the idea of "a string of pearls," suggesting a number of software packages linked together by a common infrastructure. Trilinos was developed at Sandia National Laboratories from a core group of existing algorithms, and utilizes the functionality of software interfaces such as the BLAS, LAPACK, and MPI (the Message Passing Interface for distributed-memory parallel programming).〔(【引用サイトリンク】 publisher = Sandia National Laboratories )〕 Several supercomputing facilities provide an installed version of Trilinos for their users. These include the National Energy Research Scientific Computing Center (NERSC),〔(【引用サイトリンク】url=http://www.nersc.gov/users/software/programming-libraries/math-libraries/trilinos/ )〕 Blue Waters at the National Center for Supercomputing Applications, and the Titan supercomputer at Oak Ridge National Laboratory. Cray supercomputers come with Trilinos installed as part of the Cray Scientific and Math Libraries. == Features == Trilinos contains packages for: * Constructing and using sparse graphs and matrices, and dense matrices and vectors. * Iterative and direct solution of linear systems. * Parallel multilevel and algebraic preconditioning. * Solution of non-linear, eigenvalue and time-dependent problems. * PDE-constrained optimization problems. * Partitioning and load balancing of distributed data structures. * Automatic differentiation. * Discretizing partial differential equations. Trilinos supports distributed-memory parallel computation through the Message Passing Interface (MPI). In addition, some Trilinos packages have growing support for shared-memory parallel computation. They do so by means of the Kokkos package in Trilinos, which provides a common C++ interface over various parallel programming models, including OpenMP, POSIX Threads, and CUDA. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Trilinos」の詳細全文を読む スポンサード リンク
