This article explores Amdahl's Law, which quantifies the theoretical limits on speedup gained through parallel processing. It emphasizes that while increasing the number of threads can lead to performance improvements, the actual benefit is constrained by the fraction of work that can be executed in parallel. The article provides insights on determining the optimal number of threads based on the nature of the computational tasks and the concept of diminishing returns in concurrency.
Amdahl's Law reveals the potential speedup of a process based on the fraction of work that can be parallelized and how many cores or threads are available.
When considering concurrency, knowing that not all tasks can be parallelized is crucial in determining the optimal number of threads for a process.
