Onyx2, codenamed Kego, is a family of visualization systems. It was developed and manufactured by SGI, and introduced in 1996 to succeed the Onyx. Onyx2 architecture is based on Origin 2000 server plus graphics hardware. In 2000, the Onyx2 was succeeded by the Onyx 3000, and it was discontinued on June 27, 2003
The RealityEngine2 is the original high-end graphics subsystem for the Onyx and was found in two different versions: deskside and rack. The deskside model has one GE10 (Geometry Engine) board with 12 Intel i860XP processors, up to four RM4 or RM5 (Raster Manager) boards, and a DG2 (Display Generator) board. [4]
A stone is ground into shape (often a cabochon or a short, wide cylinder) and polished to a shine. Sometimes the flat surface is engraved with a religious motto in Arabic, which is sometimes inlaid with gold. The finished gem is then mounted on a ring according to the stones finished size.
The 512-CPU Origin 2800s cost roughly $40 million each and the delivery of the Origin 3000 systems, scalable up to 512 or 1024 CPUs at a lower price per performance, made the 512-CPU Origin 2800 obsolete. Several customers also bought 256-CPU Origin 2000 series systems, although they were never marketed as a product by SGI either.
Malachite is a copper carbonate hydroxide mineral, with the formula Cu 2 CO 3 (OH) 2.This opaque, green-banded mineral crystallizes in the monoclinic crystal system, and most often forms botryoidal, fibrous, or stalagmitic masses, in fractures and deep, underground spaces, where the water table and hydrothermal fluids provide the means for chemical precipitation.
Chalcedony (/ k æ l ˈ s ɛ d ə n i / kal-SED-ə-nee or / ˈ k æ l s ə ˌ d oʊ n i / KAL-sə-doh-nee) [2] is a cryptocrystalline form of silica, composed of very fine intergrowths of quartz and moganite. [3]
It is made of tiny spheres of silicon dioxide, which stack onto each other in a pyramid grid shape. This grid is what allows the cat's-eye effect to be displayed when the stone is cut into a ball. When opalite glass is placed against a dark background, it appears to have a blue color.
