Sun Micro Improves Servers' Performance

マルチコアとマルチスレッドの組み合わせで性能を高める。やっていることは正しいが，ブレークスルーがなく閉塞感が漂う今日この頃である。

Companies are using several technologies to do more computing jobs in parallel. One technology puts the core circuitry of multiple calculating engines on each piece of silicon, creating what are called multicore chips. Multithreading technology allows each processor core to do multiple tasks at the same time.

Sun uses both techniques in a line of chips, code-named Niagara, that are a variant of its internally developed Sparc microprocessor line. The company developed a second generation in the family, which features eight processors that each can execute eight threads simultaneously, or 64 instructions in all
