Performance Metrics
4.1 Parallel Performance Metrics
Speedup and efficiency are the most common metrics used by the parallel community. Speedup can be defined as the ratio of the execution time of parallel implementation (Tp) and the execution time of the sequential one (Ts) (Eq. (4.1)), and efficiency is the normalized value of the speedup regarding the number of cores (m) executing a parallel algorithm (Eq. (4.2))

In conventional parallel computing, the speedup allows ...
