Numerical Software that I have found useful:
CitcomS is a finite element program for modeling mantle convection in a spherical shell
aspect is a community-developed mantle convection code with adaptive mesh refinement
PETSc is a library for parallel scientific computing
MUMPS (Parallel Direct Solver)
deal.ii is a finite element library with adaptive mesh refinement (AMR)
FEAP is a finite element analysis package written by R.L. Taylor at Berkeley
Triangle by Jonathan Shewchuk is a useful mesh generator
HPC on OSX provides up-to-date gnu compilers for OS X
NumPy for Matlab Users - NumPy and matplotlib provide much of the functionality of Matlab at no cost

Technical stuff:
Github repository (mostly private)
Coeus system status (on-campus only)
