Basic Requirements

Please check the following:

  1. The first thing you need is an installed (and working!) version of Trilinos. The following packages must be installed: Teuchos, Epetra, EpetraExt, Amesos, IFPACK, AztecOO, ML. You also need to enable PyTrilinos by adding --enable-python to your Trilinos configure script. Finally, you must have installed Trilinos by typing make install at the top Trilinos directory.

  2. IMPORTANT: You probably want to add a password protection to the directories WebTrilinos/c++ and WebTrilinos/python! Instructions on how to do it can be found here. The MatrixPortal module can be left without protections, depending on your needs.

  3. You need PHP installed on your system. PHP must process both .php and .html files. The line below should not contain any <? or ?>. If it does, check your web server installation, to be sure that PHP takes care of .html as well.



  4. You need convert installed on your system. Below you have the location of convert as defined by /bin/env.

    .

    If nothing is found, then you will not be able to plot the sparsity pattern in the MatrixPortal module.

  5. You need PyChart to plot results in the MatrixPortal module. If you don't have it, you can still WebTrilinos, but without graphs in the MatrixPortal module. PyChart can be downloaded at the web page http://home.gna.org/pychart/. Below you have the output of python -c "from pychart import *". If nothing is reported, PyChart is correctly installed on your system.


Go to the setup page, or go back to the home page.
