Repeat Problem 6-15 but with a round room of diameter 20 ft and a point heat source in the center at 100°C; the walls are at 20°C.

Problem 6-15

Figure 6.19 shows a room that has four walls and a fireplace. The temperature of the wall is 20°C, and the temperature of the fireplace is 100°C. Write a parallel program using Jacobi iteration to compute the temperature inside the room and plot (preferably in color) the temperature contours at 10°C intervals using Xlib calls or similar graphics calls as available on your system. Instrument the code so that the elapsed time is displayed. (This programming assignment is convenient after a Mandelbrot assignment because it can use the same graphics calls.)
