[CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]


Eff = (T*P)/M


Eff = T*(M/P)


Eff = T/(P*M)


Eff = T*P*M

Detailed explanation1: 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 explanation2: 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 explanation3: Parallel Programming Concepts: Efficiency In parallel computing, efficiency is the proportion of simultaneously available resources utilized by a computation.
Detailed explanation4: 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).
