单项选择题
MIMD systems can be classified into (150) -oriented systems, high-availability systems and response-oriented systems.
The goal of (150) -oriented multiprocessing is to obtain high (150) (151) minimal computing cost. The techniques employed by multiprocessor operating systems to achieve this goal take advantage of an inherent processing versus input/output balance in the workload to produce (152) and (153) . loading of system (154)
A．resource
B．resources
C．source
D．sources
答案
参考答案：B
解析：
[分析]： MIMD系统可以分为面向吞吐量的系统、高可用性系统和面向响应的系统。面向吞吐量的多处理机的目标是以最小计算成本得到高吞吐量。为达到此目标，多处理机操作系统采用的技术是利用工作负载上对于I/O平衡固有处理过程以产生系统资源平衡和负载均衡。
