A mathematician develops a program to solve systems of linear equations.
When they use distributed computing techniques to run the program on
two computers in parallel, they find a speedup of 2.
In this case, what does a speedup of 2 indicate?
Choose 1 answer:
A
The program completed in twice the time with two computers
versus one computer.
B
The program completed in half the time with two computers
versus one computer.
C
The program completed in two minutes more time with two
computers versus one computer.
D
The program completed in two minutes less time with two
computers versus one computer.

B
Key Concept
Speedup in distributed computing
Explanation
A speedup of 2 indicates that the program completed in half the time with two computers compared to one computer. This means the execution time is reduced by a factor of 2 when using two computers in parallel.
