 Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is the parallel efficiency(Eff) of an algorithm? Where a task takes time T in uniprocessor system, P is number of processors, M is time taken by each processor.
 A Eff = (T*P)/M B Eff = T*(M/P) C Eff = T/(P*M) D Eff = T*P*M
Explanation:

Detailed explanation-1: -Where a task takes time T in uniprocessor system, P is number of processors, M is time taken by each processor. (a) Eff = (T*P)/M.

Detailed explanation-2: -is the time to execute the workload on N processors. being less than one. Therefore, one can find the constants a and b by observing at least two different workloads (i.e. different Nh) for the N=1 (single processor) case.

Detailed explanation-3: -Parallel Programming Concepts: Efficiency In parallel computing, efficiency is the proportion of simultaneously available resources utilized by a computation.

Detailed explanation-4: -Speedup achieved by a parallel algorithm is defined as the ratio of the time required by the best sequential algorithm to solve a problem, T(1), to the time required by parallel algorithm using p processors to solve the same problem, T(p).
