Eye of Horus and to ward off evil. Ancient Egyptian and Middle-Eastern sailors would frequently paint the symbol on the bow of their vessel to ensure safe sea travel. Horus was the ancient Egyptian sky god who was usually depicted as a falcon, most likely a lanner or peregrine falcon. His right eye was associated with the sun god, Ra. The eye symbol represents the marking around the eye of the falcon, including the "teardrop" marking sometimes found below the eye. The mirror image, or left eye, sometimes represented the moon and the god Djehuti (Thoth). It was believed by the Greeks and
AMD Horus via the HyperTransport bus. As far as the Opterons are concerned they are in a five-way system and this is the basic Horus node (as called 'quad'). The Horus chip then provides an additional off-board interface (based on the InfiniBand standards) which can link to additional Horus nodes (up to 8). The chip handles the necessary translation between local and off-board ccHT communications. By building the CPUs around the Horus chip with 12-bit lanes running at 3125 MHz with InfiniBand technology (8b/10b encoding), this system has an effective internal speed of 30 Gbit/s. With 8 'quads' connected together, each with
