Sun Microsystems engineers have begun designing Niagara 3. This new member of the Sparc family will be built using a manufacturing process with 45-nanometer circuitry elements. Niagara 1 has eight processing cores, each able to process four simultaneous “threads” of instructions. Niagara 2 doubles the total number of threads from 32 to 64 by supporting eight threads in each of its eight cores. Niagara 3 will continue the trend. Memory bandwidth also will be increased compared with earlier models.
