How can I get started with Amesos?
Adding --enable-amesos to your configure invocation line will build a rudimentary Amesos with support for the Amesos_Klu class. The installation link under Quick links or the Documentation (development branch) link on the sidebar provides more complete installation instructions.How can I try Amesos on my favorite matrix?
After installing Amesos, take a look at amesos/example/example_AmesosFactory_HB.exe in your build tree. You can easily modify the source code of this example to load your favorite matrix in Harwell-Boeing format. Please refer to the comments in the code for more details.Alternatively, consider running Test_Basic/amesos_test.exe, which accepts matrices in several formats.
What if most tests fail in an MPI environment?
If "a_trivial_mpi_test" fails, or if a large number of tests fail, there could be a problem with the underlying mpi system. Try running "lamboot" and re-running the tests.
