作业2(Computer architecture) :学期论文：IBM超级计算机，沃森（注8页）
In February 2011, Watson, the IBM Supercomputer defeated Jeopardy's titans of trivia Ken Jennings and Brad Rutter on TV in front of perhaps millions of Jeopardy fans. Watson is a sophisticated computer system that uses natural language processing and artificial intelligence to answer questions. Watson is able to access 200 million pages of structured and unstructured content stored in four terabytes of disk storage. Watson is made up of a cluster of ninety IBM Power 750 servers with a total of 2880 POWER7 processors and 16 TB of RAM.
沃森现在正在应用于帮助井口的医学诊断（https://prn.to/nqkrel), help analyze customer needs and process financial, economic and client data for Citigroup (https://buswk.co/zUUUOF), and other areas.
写八到十（8）页的纸：
Study and closely examine the following Watson hardware components:
1.处理器 - 沃森使用近3,000个处理器执行指令和过程数据。
A。说明使用3,000个处理器如何使Watson的计算功能受益。
b. Determine whether or not doubling, tripling, or quadrupling the number of processors would have an effect. Explain why or why not.
2. RAM-沃森使用16个随机访问存储器。
A。确定大量RAM是否帮助Watson Process数据页面更快。
b. Predict the possible effects of doubling the amount of Watson's RAM.
3.网络 - 沃森使用需要通信网络的服务器群。用吞吐量，传输速度和可靠性协议来解释服务器之间通信网络的要求。
4. Disk storage - Watson analyzes a large number of pages per unit time to extract analytic information. Explain how Watson is able to store large amounts of data. Include the disk space requirements, the access times for reading and writing, throughput, and disk architecture.
Analyze the software components used to build Watson. In your analysis address the following components:
5. IBM DEEPQA -DEEPQA是一种庞大的平行概率基于证据的结构，使沃森能够分析，合成证据，等级和产生答案。确定至少五个挑战的挑战，即集成DEEDQA体系结构中使用的许多组件（请参阅DeepQA架构图https://bit.ly/hgtesv）。
6. Suse Linux Enterprise Server 11 O / S -IBM决定使用此操作系统，而不是基于Windows的Apple OS X Lion。
- 解释使用Suse Linux作为Watson的操作系统的原因。
- 确定您是否将其他操作系统用于Watson，并解释原因或为什么不这样做。
7. Apache Hadoop框架 - 此框架允许构建用于分布式处理的应用程序。根据以下方式确定数据可访问性的挑战：
A。可靠性
b. Scalability
c. Data errors and failures
d。高可用性
8. Apache UIMA框架 - 这是无组织信息管理框架，使应用程序可以分解为组件。解释Watson中基于Java的UIMA框架的原因，尤其是在Watson组件之间的数据流程方面。
9.沃森已应用于其他环境，例如医疗保健和通信生态系统。
- Identify the components that allow Watson to be usable in these systems (i.e. exchangeability of components).
- Determine if Watson can be applied to any IT ecosystem. Explain why or why not.
10. Watson applies natural language processing to solve problems and answer questions. Determine whether computer systems that support this type of processing can be considered to be equal or equivalent to humans' ability to think.
11.在本任务中至少使用三（3）个质量资源。
