文摘
Parallel jobs require more than one processor at the same time. We study speed scaling scheduling of parallel jobs with preemption. We propose “almost-exact” algorithms for problems with rigid jobs and single mode two-processor jobs. Based on configuration linear programs, our algorithms obtain an \(OPT + \varepsilon \) solution for any fixed \(\varepsilon > 0\).
