The Raptor HPC Project is headed by SOSDG Volunteer Systems Engineer Gregory Taylor out of Seattle, WA to create a fully functional open source mini HPC cluster system for military, medical and research applications on a modified Hypercube computer model.
The foundation stone in the form of a letter labyrinth ("Silo Princeps Fecit") inspired the hypercube of Salvador Dalí's painting A Propos of the "Treatise on Cubic Form" by Juan de Herrera, housed in the Museo Reina Sofia, Madrid.
Released in 2002, Cube 2: Hypercube had a bigger budget than its predecessor, and a new director, Andrzej Sekuła.
As with the hypercube graphs, and their isometric (distance-preserving) subgraphs the partial cubes, a halved cube graph may be embedded isometrically into a real vector space with the Manhattan metric (L1 distance function).
