超級(jí)計(jì)算機(jī)
超級(jí)計(jì)算機(jī)(supercomputers)通常是指由數(shù)百數(shù)千甚至更多的處理器(機(jī))
Supercomputers usually refer to hundreds of thousands or more processors.
組成的、能計(jì)算普通PC機(jī)和服務(wù)器不能完成的大型復(fù)雜課題的計(jì)算機(jī)。超級(jí)計(jì)算機(jī)是計(jì)算機(jī)中功能最強(qiáng)、運(yùn)算速度最快、存儲(chǔ)容量最大的一類(lèi)計(jì)算機(jī),是國(guó)家科技發(fā)展水平和綜合國(guó)力的重要標(biāo)志。超級(jí)計(jì)算機(jī)擁有最強(qiáng)的并行計(jì)算能力,主要用于科學(xué)計(jì)算。在氣象、軍事、能源、航天、探礦等領(lǐng)域承擔(dān)大規(guī)模、高速度的計(jì)算任務(wù)。在結(jié)構(gòu)上,雖然超級(jí)計(jì)算機(jī)和服務(wù)器都可能是多處理器系統(tǒng),二者并無(wú)實(shí)質(zhì)區(qū)別,但是現(xiàn)代超級(jí)計(jì)算機(jī)較多采用集群系統(tǒng),更注重浮點(diǎn)運(yùn)算的性能,可看著是一種專(zhuān)注于科學(xué)計(jì)算的高性能服務(wù)器,而且價(jià)格非常昂貴。一般的超級(jí)計(jì)算器耗電量相當(dāng)大,一秒鐘電費(fèi)就要上千,超級(jí)計(jì)算器的CPU至少50核也就是說(shuō)是家用電腦的10倍左右,處理速度也是相當(dāng)?shù)目?,但是這種CPU是無(wú)法購(gòu)買(mǎi)的,而且價(jià)格要上千萬(wàn)。
Computers consisting of large and complex subjects that can be computed by ordinary PCs and servers. Supercomputers are the most powerful, fast and storage computers in computers. They are important symbols of the development level of national science and technology and comprehensive national strength. Supercomputers have the strongest parallel computing power and are mainly used in scientific computing. It undertakes large-scale and high-speed computational tasks in meteorology, military, energy, aerospace, prospecting and other fields. In structure, although supercomputers and servers may be multi-processor systems, there is no substantial difference between them, but modern supercomputers mostly use cluster systems and pay more attention to the performance of floating-point computing. It can be seen that they are a high-performance server focusing on scientific computing, and the price is very expensive. Usually, supercalculators consume a lot of power, which costs thousands of power in one second. The CPU of supercalculators is at least 50 cores, which is about 10 times faster than that of household computers. But this kind of CPU can not be purchased, and the price is tens of millions.
