ITPEC IP October 2022 Question 23
Which of the following is an appropriate typical example of a system operating on a super computer?
Explanation
Global climate change prediction — a supercomputer is built for large-scale scientific and technical computation.
A supercomputer links a very large number of processors to run massive numerical calculations at extreme speed. Its typical uses are simulations: weather and climate forecasting, earthquake and tsunami modelling, fluid dynamics, molecular and drug design. A global climate model repeats physical equations over millions of grid points across decades of simulated time, exactly that kind of work.
Answer (b)
Why not others:
- •(a) — an SCM system links the ordering and stock data of several companies; it needs networked business servers, not huge computing power
- •(c) — a banking system needs high reliability and transaction throughput, the traditional role of a mainframe (general-purpose computer)
- •(d) — engine control runs on a small embedded microcomputer in the vehicle that reacts in real time
Key rule: Match the computer to the workload: supercomputers for scientific calculation, mainframes for reliable large-scale transactions, embedded microcomputers for real-time control.
