trilinos Overview

The Trilinos Project develops algorithms and enabling technologies within an object-oriented software framework for the solution of large-scale, complex multi-physics engineering and scientific problems.

Support

Usage

Trilinos provides abstract, object-oriented interfaces to established libraries such as Metis/ParMetis, SuperLU, Aztec, BLAS, and LAPACK. Note: The Trilinos module is dependent on the petsc, xt-libsci, and xt-asyncpe modules. Make certain these modules are loaded before using Trilinos. Trilinos includes a new version of Cray Adaptive Sparse Kernels (CASK) that perform SpMV, and include optimized versions of single- and multiple-vector sparse matrix vector multiplication and triangular solution kernels. These have been shown to provide improved performance over native Epetra SpMV under most circumstances and especially to improve the performance of operations with very sparse matrices. The Trilinos Project is an ongoing effort to develop and implement robust algorithms and enabling technologies using modern object- oriented software design. Trilinos emphasizes abstract interfaces for maximum component interchangeability and provides a full- featured set of concrete classes that implement all abstract interfaces. Each Trilinos package is a self-contained and independently developed piece of software. To use the Trilinos packages, load your choice of compiling environment, and then load the Trilinos module. 
module load trilinos
After you load the Trilinos module, all header and library locations are set automatically and you are ready to compile your code. No Trilinos-specific linking information is required on the command line. For example, to use the Epetra library, use a compiler command line like the following example. 
CC myprogram.cpp.o -o myprogram.exe
If linking to more than one Trilinos package, the libraries are linked automatically in the correct order of package dependency. For more information about link order, see http://trilinos.sandia.gov/packages/interoperability.html. For more information please run: 
man trilinos
