For a given problem size, as we increase the number of processing
elements, the overall ?
of the parallel system goes down for all
systems. *
replace ?

1.)Speed
2.)Cost
3.)Efficiency
4.)Total overhead​

Answer 1

Answer:

elements, the overall ?

of the parallel system goes down for all

systems. *

replace ?

1.)Speed

2.)Cost

3.)Efficiency

4.)Total overhead

Answer 2

Explanation:

A parallel algorithm is cost optimal when its cost matches the run time of the best known sequential algorithm Ts for the same problem. ... Its efficiency E is the ratio of the speed up to the number of processors used (so a cost optimal parallel algorithm has speed up p and efficiency 1 (or Θ (1) asymptotically).

4) 1

2) For a given problem size, as we increase the number of processing elements, the overall efficiency of the parallel system goes down for all systems.

3) efficiency.

plz plz mark me brainlist :-).
