Setup Parameters:
-
Number of Processes:
Sets how many processes (simulated processors) will divide and compute the trapezoidal areas.
-
Number of Subintervals: Set the precision of the computation, i.e., the
number of intervals the function will be divided into, which impacts the accuracy of
π computation.
...
-
Initialize the Experiment:
-
After setting the desired number of processes and subintervals, click Start
Calculation to begin.
-
The animation will display trapezoids being computed by each process within a visual representation
of the integral, displayed on the canvas. Observe the different trapezoid areas calculated by each
process as they appear sequentially.
-
Monitor Process Controls:
In the Process Controls section, adjust the speed of each process using the
slider to simulate processors running at different speeds. Observe how this affects the overall
computation time in the Results section.
-
Analyze Results:
As the computation progresses, the Results section displays:
-
Computed π:
The approximation of
π as calculated by the processes.
-
Wall-clock Time:
The real time taken for the computation, which reflects the overall efficiency when using
multiple processes.
-
Process Time:
The total computation time for all processes combined, used for calculating efficiency.
-
Reset if Needed:
To rerun the experiment with different parameters, click the "Reset" button.
This clears previous results and resets the canvas.
