SOFTWARE
PROJECTS
	AUTO2000
	(with E. Doedel)
	A translation to C, and optimized parallel implementation of, AUTO (Doedel, Wang, et. al.). The parallel portions of the code have been designed to be portable across different communication paradigms, and implementations are available using either message passing (with either MPI or PVM) or shared memory (with Pthreads). It has been used on a heterogeneous network of Linux workstations, SUN SMPs, SGI SMPs, and an HP Exemplar. (Developed with ~30,000 lines of C and ~6,000 lines of Python).
	VBM: Visualization for Bifurcation Manifolds
	A general scientific visualization code for Multi-point Boundary Value problems. Developed using DataViewer, Python, C++ and Fortran with ~10,000 lines of Python ~3,000 lines of C++.
	DataViewer
	(with T. Stone, A. Ahearn, and J. Maddocks)
	A general object oriented data visualization and processing tool. Developed in C++ and OpenGL with ~27,000 lines of C++.
	MCCC: Multi-parameter Computation and Continuation Code
	An objected oriented toolkit for the development of parameter continuation algorithms. Developed in Java with ~5,000 lines of code.
	SLINKY
	(with K. A. Rogers)
	A computer graphics code which integrates the equilibrium equations of a rod. Developed in AVS5 with custom Fortran and C modules.
	PVM Parallel AUTO (Doedel, Wang, et al.)
	An implementation of Parallel AUTO (Doedel, Wang, et al.) using the PVM message passing libraries.
	AvA: AUTO Visualization Application
	(with V. Kalb, J. Maddocks, and C. Mesztenyi)
	A visualization and computational steering code. Developed in C++, OpenGL, and Fortran with ~9,000 lines of C++.
