simple_stratimikos_example.cpp

Simple example program for how the Stratimikos::DefaultLinearSolverBuilder class is used to take a parameter list (e.g. read from a file) and use it so solve a linear system read in as Epetra objects from a file.

Command-line options for the driver program

Example input XML file

Here is an example input XML file, called amesos.klu.xml, that specifies that the KLU solver from Amesos be used to solve the linear system:

Example program output

Sample output looks like when using the above amesos.klu.xml file as input with a test system:
