Static and dynamic nuclear many-body descriptions on parallel architectures
Numerical methods used to solve the system of stiff, nonlinear partial differential equations in static Hartree-Fock descriptions of many-body nuclear systems are presented along with an extension of the time dependent Hartree-Fock solution to linear response theory. A full three dimensional representation is obtained by using a collocation basis spline spatial lattice. Numerical procedures used for parallel applications are discussed. Comparisons are presented for MIMD massively computers, including the Intel Paragon and the iPSC/860 hypercube. Algorithms used to improve communication overhead, especially pipelining the Gramm-Schmidt orthogonalization routine, and difficulties with limited node memory will be discussed.
