    Study Notes

    Parallel Efficiency in Cloud Computing

    • Parallel efficiency is a metric in cloud computing that measures the effectiveness of using multiple processors to speed up a task.
    • It's calculated as the ratio of the time taken on a single processor to the time taken on multiple processors, normalized by the number of processors used.
    • A higher parallel efficiency indicates better performance gains from parallelization.
    • If a task takes a time 'T' on a uniprocessor system, then the time taken on P processors parallelly is 'T/P' (ideal case).
    • The parallel efficiency (Eff) is defined as (T/P) / (T * Eff) = 1/Eff.
    • Therefore, Eff = 1/P.
    • In a uniprocessor system, the efficiency is 1 (Eff = 1).
    • The efficiency decreases as the number of processors increases.
    • Therefore, parallel efficiency is inversely proportional to the number of processors.
    • The ideal parallel efficiency of 1 can only be achieved if the task is perfectly parallelizable and there is no overhead associated with parallel processing.
    • In practice, this is rarely the case, and the efficiency is typically lower than 1.
    • Parallel Efficiency is crucial for optimizing cloud computing applications to take full advantage of available resources.
    • It is a significant factor in determining the cost-effectiveness of using cloud computing platforms.
    • Factors that impact Parallel Efficiency:
      • Overhead of parallelization (e.g., communication between processors)
      • Task complexity (e.g., the ability to divide the task into independent subtasks)
      • Load balancing among processors.
