Design job pool framework that supports n concurrency. Another person asked design lift software with minimal power consumption in mind. He also asked me to consider a resource grid system and design resource request submission and processing software. Question was abstract. Another person asked design thread pool where it has to execute n process with dependency with each process taking input files and output files. Here it is expected for you to figure out process dependency by comparing input files and output files of processes. You are also given each process completion time. Process with dependency cannot start until depended process(s) has finished. Your tasks is to figure out dependency, and overall completion time.
