解説
問 79
Incorrectア
An SCM (supply chain management) system is a core business system that links data such as orders, inventory, and logistics between companies, and what it requires is network coordination and mechanisms for processing and managing data. Such processing does not need enormous numerical computing power, so it is built on ordinary servers or cloud platforms, and it is not a use case for a supercomputer.
- イ
正解 A supercomputer is a computer with the highest performance of its time, specialized in executing huge numbers of calculations at ultra-high speed through parallel processing. Its main uses are large-scale scientific and technical computation (numerical simulation), such as weather and climate simulation, space and astronomical analysis, simulation of molecules and new materials, and fluid analysis. Choice イ, a global-scale weather change prediction system, requires dividing the entire earth into fine grid cells and solving physical equations an enormous number of times, which is exactly a typical example of large-scale scientific and technical computation, so it is appropriate as a system to run on a supercomputer.
Incorrectウ
What a banking system requires is nonstop operation and accuracy of transaction data, that is, high reliability and availability. This is achieved with machines such as mainframes that have redundant configurations or fault-tolerant designs, and it is not the domain of a supercomputer, which gives top priority to computing speed.
Incorrectエ
An automobile engine control system is an embedded system that requires high real-time performance, always finishing its processing within a fixed time, and it uses a small, low-power configuration that runs a real-time OS on a microcontroller. A supercomputer, which is large and consumes a great deal of power, cannot be mounted in a car, and the property required here is not computational scale either.
ここがポイント
- A supercomputer is the highest-performance computer, which carries out ultra-high-speed calculation through parallel processing; it is used for large-scale scientific and technical computation such as weather prediction, space analysis, and molecular simulation.
- Remember the classification of computers by the property that is required: computing performance first means a supercomputer, reliability and high-volume core business processing means a mainframe, and real-time performance with small size and low power means an embedded (microcontroller) system.
