スーパーコンピュータと科学技術計算の最新動向

摘要

科学技術用の高速計算機を一般にスーパーコンピューrnタと呼ぶ．どの程度の性能のものをいうかは時代によっrnて大きく異なっている．現在のパソコンは初代のスーパrnーコンピュータよりはるかに高速である．%More than 60 years have passed since the first electronic computer ENIAC was completed. The speed of the ENIAC was about 300 flops, that is, it can perform 300 floating operations in a second. The speed of the fastest computer today is 10~(12) times higher than that. Japan is building a next-generation supercomputer (so called Keisoku Computer) which will have twenty times higher performance until 2011. The future trends of scientific computation using such huge computing facility will be discussed.
