Compile PETScД«y default, we use PETSc submodule inside of MOOSE as our nonlinear/linear solvers. Leave this module loaded for the remainder of the instructions (PETSc requirements). While we are at it, verify that your MPI wrapper works by running a few commands (your results will vary, but they should return something): Verify that this module loads properly by attempting to echo $PETSC_DIR: echo $PETSC_DIR With the modulefile in place and the MODULEPATH variable set, see if our module is available for loading: That way, the above is performed as the user logs into the machine. The above command should be added to the list of other global profiles (perhaps in /etc/profiles.d). To make the module available in your terminal session, export the following:Д®xport MODULEPATH=$MODULEPATH:$PACKAGES_DIR/modulefiles Replace GCC and MPI paths with any additional information needed to make GCC/MPI work on your cluster. As an example, if you left packages_dir as: /opt/moose, then that is what you would enter) Replace INSERT PACKAGES_DIR HERE with whatever you had set for $PACKAGES_DIR ( do not literally enter: $PACKAGES_DIR. That way, the things we do install can be done so without invoking sudo: So let us create and chown the $PACKAGES_DIR directory before we install anything.

History teaches us, that implicitly trusting scripts we download off the internet with root access, is a very bad idea. All files related to libraries necessary to build MOOSE, will be stored in this location ( choose carefully, as this location should be accessible from all nodes on your cluster): We need to adjust our umask so that when you write a file ( make install), it is readable by everyone:Д®xport a base path variable which will be the home location for the compiler stack. Environment SetupД«egin by creating an area for which to build:Д®xport STACK_SRC=`mktemp -d /tmp/stack_src_temp.XXXXXX` Please use a single solitary terminal session throughout and to the completion of these instructions.
