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.

Trilinos Capability Areas

Due to the large number of capabilities and packages that are delivered through Trilinos we have divided the project into capability areas. The Trilinos Capability Area homepage introduces the eight Trilinos Capability Areas.

Trilinos Packages

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.
