当前计算机技术的发展令人眼花瞭乱。集成度随时间按指数增加,体积越来越小,速度越来越快,内外存越来越大,费用越来越低,使用越来越方便。根据国外情报资料,预计在今后五年内,将出现4MB的内存蕊片,一台微型机的内存将可达到512MB,大约是现在IBMpc机的1000倍;光盘容量可达5万MB;巨型机的浮点运算速度可望达到每秒百亿次;而计算机的花费将大体上按每八年降低10倍的速度下降。各种各样的并行机和相应的并行算法和软件正在出现,
The current development of computer technology is dazzling. The degree of integration increases exponentially with time, the volume is getting smaller and smaller, the speed is getting faster and faster, the internal and external memory is getting bigger and bigger, the cost is getting lower and lower, the use is more and more convenient. According to foreign intelligence data, it is estimated that within the next five years, there will be 4MB of memory chip, a microcomputer memory will reach 512MB, about 1000 times IBMpc machine now; CD-ROM capacity of up to 50,000 MB; Jumbo machine Floating-point computing is expected to reach tens of billions of times per second; and the cost of computers will generally drop by a factor of 10 every eight years. A variety of parallel machines and corresponding parallel algorithms and software are emerging,
