Phylogenetics Relationships of groups of organisms as reflected by their evolutionary history

Stiff differential equations Coupled differential equations that include some terms that lead to rapid variations; they must be handled with special solvers to avoid instabilities

Symplectic integrators Discretizations that have a Hamiltonian structure analogous to that of the dynamics being approximated

Teraflop Trillion floating point operations

Terascale Computing at trillions of flops per second
