From "top", the memory usage for this program is around 2-3GB and the node I am running this program on has a total RAM of 32GB, most of which is available. In principle, I should be able to use the rest of the resources and run even much bigger simulations.
This is only true if Python and all the supporting libraries (NumPy, PySparse, etc.) are compiled to take advantage of 64 bit addressing. If they're 32 bit, then it's unsurprising that you're limited to something less than 4GB.
What does >>> import platform >>> platform.architecture() report?
