How can I measure the performance of parallel algorithms?
You can measure performance using metrics like speedup, efficiency, and scalability. Would you like to know more about these metrics?
Yes, what is speedup in this context?
Speedup is the ratio of the time taken to complete a task using a single processor to the time taken using multiple processors. It indicates how much faster a parallel algorithm runs compared to its sequential counterpart.
How do I calculate efficiency?
Efficiency is calculated as the speedup divided by the number of processors used. It shows how effectively the processors are utilized.
What about scalability?
Scalability refers to how well a parallel algorithm can maintain performance as the number of processors increases. A scalable algorithm will show consistent speedup with more processors.
