4. Adaptive Thick Restart Lanczos Algorithm (for low-lying eigenmode projection) Dedicate for Hermition matrix A. Can attain > 50% better performance than ARPACK k is optimized for the best performance via maximize of the following object function

5. Scientific package development (coordinated by Dir. Chang)‏ Motivation Current available packages treat the whole system altogether, which requires enormous computing resources. Cannot handle large complicated nano-particles, nor the interaction between nano-particles. We need a new ab-initio computation method to handle large complicated nono- structures with good accuracy. Idea Using the boundary-integral method to solve the whole Green's function from the ones in sub-domains.
