Abstract

Current constraint solvers in GROMACS converge linearly at best. Newton's method converges quadratically and the applicants current work is focused on writing a specialized linear solver which is can exploit the repetitive nature of real molecules such as proteins and fatty acids in order to achieve vector level parallellism.
