科学计算应用变碍一年比一年复杂,要求也越来越高,这就导致了对具有更高性能系统的需要。但由于开支的限制,需要减少所有费用。联想到保护研制软件的费用。以及对高效率系统日益增长的要求,义须考虑一种新的方法。(?)系统复杂的原因是由于以并行方法同时处理多个单独任务今天所能提供的典型解决方法是采用昂贵的主机或采用在共享存贮环境下多个小型计算机。 The advent of scientific computing applications is becoming more complex and demanding year after year, resulting in a need for systems with higher performance. However, due to cost constraints, all costs need to be reduced. Think of the cost of protecting development software. And the growing demand for high-efficiency systems, a new approach must be considered. (?) The complexity of the system is due to the costly host or the use of multiple small computers in a shared storage environment, due to the typical solution that can be offered today with the simultaneous processing of multiple separate tasks.
