Welcome to the Trilinos Project Home Page
We have FINALLY begun to migrate to trilinos.org! We will be moving existing content to the new server and adding new content. During the move, there will be some content on the old server, and some on the new server. Please excuse our mess during the move to trilinos.org. In the end, it will be worth the inconvenience. The initial focus of the move will be on user-focused Trilinos-level content, then user-focused package-level content. The focus will then shift to developer-focused content including issue tracking, and other tools like some of the mail lists.
The Trilinos Project is an effort to develop algorithms and enabling technologies within an object-oriented software framework for the solution of large-scale, complex multi-physics engineering and scientific problems. A unique design feature of Trilinos is its focus on packages.
Trilinos 11.8 Release
Trilinos 11.8 is now available for download. The 11.8 release uses a CMake build system, which requires CMake version 2.8 or greater. Instructions for building Trilinos 10.0 and later are available here.
What Trilinos Can Do: Trilinos Capability Areas
The Trilinos Capability Area homepage organizes Trilinos capabilities into nine collections of functionality and describes which packages are relevant to each area. This discussion is especially useful for new Trilinos users.
The 2014 European Trilinos User Group Meeting was held June 30th – July 1st in Lugano Switzerland, just prior to the 8th International Workshop on Parallel Matrix Algorithms and Applications (PMAA14).
Trilinos User Group 2013
The 2013 Trilinos User Group Meeting (TUG) was held November 4th-8th in Albuquerque. The meeting will featured two days of user-focused content, followed by one day of Trilinos developer presentations and discussions and two days of focused developer activity. For more information, visit the TUG 2013 Homepage. Also, visit the TUG 2012, TUG 2011, and TUG 2010 homepages for videos and slides from past meetings.
EuroTUG 2012 and 2013
The first ever European Trilinos User Group Meeting took place June 4th-6th, 2012 at EPFL Lausanne. Slides and abstracts for some talks are now available. The 2013 European Trilinos User Group Meeting was held June 3rd-5th in Munich, Germany.
Trilinos Featured in RCE HPC Podcast
Trilinos was featured in a Research, Computing, & Engineering (RCE) High Performance Computing (HPC) podcast hosted by Brock Palen and Jeff Squyres. The podcast includes a very high-level summary of Trilinos and touches on other interesting topics like the origin of the name “Trilinos”. Visit the RCE-cast website for more details and to download the podcast.
Each Trilinos package is a self-contained, independent piece of software with its own set of requirements, its own development team and group of users. Because of this, Trilinos itself is designed to respect the autonomy of packages. Trilinos offers a variety of ways for a particular package to interact with other Trilinos packages. It also offers a set of tools that can assist package developers with builds across multiple platforms, generating documentation and regression testing across a set of target platforms. At the same time, what a package must do to be called a Trilinos package is minimal, and varies with each package.
Trilinos 9.0 (Autotools Build System)
The Autotools build system is no longer available starting with Trilinos 10.0. Users can still download the 9.0 release for access to the Autotools build system.
