We consider the numerical solution on distributed-memory parallel arrays of vector processors of some large-scale eigenvalue problems which arise in chemistry and physics. Applications from a variety of areas are discussed, including molecular dynamics, quantum chemistry, optical physics, chemical reactions, and hydrodynamic stability.

The role of solution chemistry (cation charge and concentration) and particle size on colloid transport was examined in an intact monolith of fractured shale saprolite (highly weathered rock). Recovery of the microsphere tracers consistently decreased with increasing ionic strength of either mono- (Na+) or divalent- (Ca2+) dominated solutions, but a much greater concentration of Na+ in the infl...
