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. The package has two building methods, the default is for a single system (without parallelism). * The trilinos can also be compiled against individual packages (i.e. amd, umfpack and metis) outside of suitesparse.SlackBuild. ** The suitesparse.SlackBuild, doesn't build metis by default. For that you can use the parMETIS.SlackBuild. For more details about dependeces the Xyce webpage. have a list of required depences. Optional dependences: For enable parallelism set PARALLEL=yes. This requires the ParMETIS library and a MPI implementation (openmpi or mpich). To enable CUDA set CUDA=yes (Additional requirements: CUDA SDK and CUSPARSE).
