Which of the following best describes the ability of parallel computing solutions to improve efficiency?
answer choices
Any problem that can be solved sequentially can be solved using a parallel solution in approximately half the time.
Any solution can be broken down into smaller and smaller parallel portions, making the improvement in efficiency theoretically limitless as long as there are enough processors available.
The efficiency of parallel computing solutions is rarely improved over the efficiency of sequential computing solutions.
The efficiency of a solution that can be broken down into parallel portions is still limited by a sequential portion.
