Gradually towards the development of multi-core processors and multi-threaded, 4-core Xeon processors with Intel dual-core Itanium processors or, for example, each core will have two threads, or to emphasize the frequency of IBMPower6, the same dual-core , but each core will also support two threads (Threads), but recently Sun (Sun) published UltraSPARCT2 (R & D Code: Niagara2) core number will reach 8, each core also supports eight threads, a processors will have 64 logical processors is the processor the most. Gradually towards the development of multi-core processors and multi-threading to the Intel 4-core Xeon processors or dual-core Itanium processor, for example, each core will have two threads, or to emphasize the frequency of IBMPower6, the same dual-core , but each core will also support two threads (Threads), but recently Sun (Sun) published UltraSPARCT2 (R & D Code: Niagara2) core number will reach 8, each core also supports eight threads, a processors would have 64 logical processors is the processor the most. The Sun started from Niagara2 support FB-BIMM memory, and PCIExpress and Gigabit networks built into the processor, in addition, each core also has a separate FPU. The next-generation processor, officially named VictoriaFalls, is expected to launch in the first half of next year. Support for 64 threads Attack low-end Sun server market with Niagara, the main value this market need to handle many tasks in parallel server capacity to UltraSPARCT1 processor, for example, although the frequency of up to 1.2GHz, 8 core, but it has up to 32 threads, while UltraSPARCT2 processor, clocked by only upgraded to 1.4GHz, but under the framework of the 8-core number of threads to double, to 64 threads, the process also increased to 65 nm, Sun Microsystems Yen, executive vice president of electronics, said, "UltraSPARCT2 of multi-threaded computing technology does not require an increase in frequency too few cases where performance can be compared to UltraSPARCT2 doubling the previous generation." However, IDC analyst of enterprise applications, said Zhong Wei Chang, the current trend of multi-core processors and multi-threaded development, but most of the current application only supports single-core or single-threaded, it will be to promote the greatest multi-core and multi-threading resistance. Yen said Sun will UltraSPARCT2 processor design before open to the various software vendors, more will open a trial, so that software developers can learn more about Sun multi-core and multi-threaded architecture, allow applications to support. In addition, Sun's own operating system now supports UltraSPARCT2 Solaris multi-core and multi-threaded architecture. Gigabit network processor with integrated PCIExpress Sun Niagara2 processor Another feature, is to PCIExpress, full encryption, two Gigabit network with four memory controller built-in processor. Sun Global Sales and Service, Department of Systems Engineering Society of Greater China sales technical advice manager Guo Changhong said in the past will PCIExpress and Gigabit networks built on the motherboard, or to communicate with the processor, these features are now within built into the processor, reducing the frequency of communication will pick up the pace of implementation. Niagara2 processing unit also has a convergence function, can accelerate the implementation of a variety of addition and subtraction secret work. More for the first time to support FB-DIMM memory, although compared to Niagara's DDR2 memory is more power, but in order to reduce foot median and reducing package size, to increase memory capacity and bandwidth. First-generation Niagara processor 8-core processors share a single floating-point, when the implementation of the HPC and the like requiring high floating point applications, there will be bottlenecks, and each core is assigned a Niagara2 floating-point processor, therefore, Niagara2 there are eight floating-point processors, Yen said, Niagara2 enhanced floating-point computation, is currently the industry's highest floating-point processor. Yen said, as Niagara2 in the architecture, capabilities have increased with the power consumption compared to the previous generation of 72 watts to 95 watts to upgrade. VictoriaFalls next year Niagara2 the next generation of R & D code, Sun is no longer used the name of Niagara Falls, name changed to Victoria Falls (VictoriaFalls), Yen said, named VictoriaFalls, is a whole can have a significant change. VictoriaFalls in the structure with the previous generation Niagara2 not much different, but starting from the VictoriaFalls, Sun plans to launch configuration will be more than VictoriaFalls processor system that allows a server to upgrade the performance significantly, Sun said, and UltraSparcIIIi processor server configuration compared to the first generation Niagara server performance by 13 times, as Niagara2 server is upgraded to 34-fold, to configure VictoriaFalls processor servers will be up to 64 times. October this year, Sun will officially launch the server using Niagara2 to the first half of next year, will be available VictoriaFalls, to the second half of next year, Sun will launch 16-core Rock processor, Yen said, because these processors product areas septum, currently contains the server with Niagara and Niagara2 will coexist for some time, and Rock processors will be mainly high-end applications.
