Suppose Program A, when run on a certain computer, records a user CPU time of 3 seconds, an elapsed wallclock time of 4 seconds, and a system performance of 10 MFLOP/sec. The computer is capable of either doing calculations in the CPU or doing I/O at any given time, but not both. If the processor is replaced with one that is six times faster without affecting the I/O speed, what will be the new user CPU time, the wallclock time, and the MFLOP/sec performance? User CPU time: 0.5 seconds, Wallclock time: 1.5 seconds, Performance: 60 MFLOP/sec User CPU time: 0.5 seconds, Wallclock time: 1.5 seconds, Performance: 40 MFLOP/sec User CPU time: 0.5 seconds, Wallclock time: 1.5 seconds, Performance: 20 MFLOP/sec ○ User CPU time: 0.5 seconds, Wallclock time: 1.5 seconds, Performance: 40 MFLOP/sec

Question
Suppose Program A, when run on a certain computer, records a user CPU time of 3 seconds, an elapsed wallclock time of 4 seconds, and a system performance of 10 MFLOP/sec. The computer is capable of either doing
calculations in the CPU or doing I/O at any given time, but not both. If the processor is replaced with one that is six times faster without affecting the I/O speed, what will be the new user CPU time, the wallclock time, and the
MFLOP/sec performance?
User CPU time: 0.5 seconds, Wallclock time: 1.5 seconds, Performance: 60 MFLOP/sec
User CPU time: 0.5 seconds, Wallclock time: 1.5 seconds, Performance: 40 MFLOP/sec
User CPU time: 0.5 seconds, Wallclock time: 1.5 seconds, Performance: 20 MFLOP/sec
○ User CPU time: 0.5 seconds, Wallclock time: 1.5 seconds, Performance: 40 MFLOP/sec
