Please read the updated Clarifications page [CITS2002]⬈ (4th September) which defines the process scheduling order. The revised sample solution schedules the processes by following this order, performs some basic checks on its input files (which you do not have to replicate), and its debug output (which you do not have to replicate) is more descriptive of what is happening. You may download a shellscript that allows you to run the sample solution from your shell's command-line, rather than requiring a web-browser. Please report any problems.
