Use of virtualization technologies is becoming prevalent, including,
but not limited to, the current commercial cloud environments. At
the same time, besides resources costs and application performance,
energy efficiency is becoming a dominant consideration while de-
signing systems and executing applications on them. The premise of
our work is that consolidation of scientific workflow tasks can be a
promising approach for energy and resource cost optimization, with-
out incurring substantial performance degradation. This is further
supported by detailed analysis of resource requirements of scientific
workflow tasks, and analysis of power consumption with use of vir-
tualization and with consolidation of workloads.
Based on the trends observed from our experiments, we have de-
veloped pSciMapper, a power-aware consolidation framework for
