Jonathan Schwartz has posted on his Sun blog
that the Rock (the codename for Sun's upcoming processor) has arrived at his desk. He mentions that this is a 16-core 2395 pin (1514 of which are used for power/grounding and 812 pins are for signaling) UltraSPARC processor. Using the Rock processor and OpenSolaris, it will allow for up to 256 terabytes of RAM in a single software domain. More on Sun's Rock CPU will be revealed in the coming weeks (JavaOne time-frame).
