Power consumed by modern computer systems, particularly servers in data centers has almost
reached an unacceptable level. However, their energy consumption is often not justifiable when
their utilization is considered; that is, they tend to consume more energy than needed for their computing
related jobs. Task scheduling in distributed computing systems (DCSs) can play a crucial role in
increasing utilization; this will lead to the reduction in energy consumption. In this paper, we address
the problem of scheduling precedence-constrained parallel applications in DCSs, and present two energy-
conscious scheduling algorithms. Our scheduling algorithms adopt dynamic voltage and frequency
scaling (DVFS) to minimize energy consumption. DVFS, as an efficient power management
technology, has been increasingly integrated into many recent commodity processors. DVFS enables
these processors to operate with different voltage supply levels at the expense of sacrificing clock frequencies.
In the context of scheduling, this multiple voltage facility implies that there is a trade-off between
the quality of schedules and energy consumption. Our algorithms effectively balance these two
performance goals using a novel objective function and its variant, which take into account both goals;
this claim is verified by the results obtained from our extensive comparative evaluation study.
