Parallel Implementation

In this stage, you are required to write code to evolve Game of Life using multiple worker goroutines on a single machine.

The following pages are some suggested steps to help you get started, you are not required to follow them.

Your implementation will be marked against the success criteria outlined here.

Step 5

Implement the following control rules. Note that the running SDL provides you with a channel containing the relevant keypresses.

• If s is pressed, save the current state of the board as a PGM image.

  NOTE: Don't forget to send an ImageOutputComplete event after a PGM image is saved.

• If q is pressed, stop executing Gol computation, save the current state of the board as a PGM image, then terminate the program.

  NOTE: Your distributor should behave as following after q is pressed:

  Complete the current turn
  Send a FinalTurnComplete event
  Save the final state as PGM image and send an ImageOutputComplete event
  Send a StateChange event and terminate

• If p is pressed, pause the processing and send a StateChange event.
  When p is pressed again, resume the processing and send a StateChange event.

  NOTE: It is necessary for q and s to work while the execution is paused.

Test

To test the visualisation and control rules, type the following in the terminal.

Test with SDL window

go test ./tests -v -run TestKeyboard -sdl

Test without SDL window

go test ./tests -v -run TestKeyboard

You can also run the program and test the control rules manually by typing the following in the terminal.

go run .
