Question 35

Which of the following is suitable as a description of computer performance evaluation?

a) With TPC, a major benchmark for online transaction processing, the measure of performance is TPS, which is objective. However, it lacks a measure of cost.
b) Dhrystone, Whetstone, Livermore Fortran Kernel, Linpack, SPEC, and the like are used as overall computer system performance benchmarks.
c) The use of multiple types of benchmarks for performance evaluation is effective for purposes such as selecting models to be installed, since the benchmark results can be used to understand system characteristics.
d) Benchmark programs are models of user programs from a system design perspective. Their results can be widely applied to models of computer performance from the user’s perspective.
