$8)$ The efficiency of a parallel implementation of a code without sequential overhead is constant.

True False

$9)$ In Amdahl's law, the problem size is assumed to be fixed.

True False

$10)$ In the plot below, the scaled speedup refers to the speedup due to the parallel implementation as the problem size is changed. The efficiency of such implementation is constant.

True False

$11)$ If the efficiency of a scaled problem remains constant as we increase the problem size, the problem is said to be strongly scalable.

True False

$12)$ Typically, in distributed computing, each processor is assumed to have its own memory.

True False
