Main memory in clusters may dominate total system power. The resulting energy consumption increases system operating cost and the heat produced reduces reliability. Emergent memory technology will provide servers with the ability to dynamically turn-on (online) and turn-off (offline) memory devices at runtime. This technology, coupled with slack in memory(More)
Main memory in many tera-scale systems requires tens of kilowatts of power. The resulting energy consumption increases system cost and the heat produced reduces reliability. Emergent memory technologies will provide systems the ability to dynamically turn-on (online) and turn-off (offline) memory devices at runtime. This technology, coupled with slack in(More)
Extraordinary improvements in computing performance, density, and capacity have driven rapid increases in system energy consumption, motivating the need for energy-efficient performance. Harnessing the collective computational capacity of thousands of these systems can consume megawatts of electrical power, even though many systems may be underutilized for(More)
Rough set theory is a popular and powerful machine learning tool. It is especially suitable for dealing with information systems that exhibit inconsistencies, i.e. objects that have the same values for the conditional attributes but a different value for the decision attribute. In line with the emerging granular computing paradigm, rough set theory groups(More)
umlsim extends user-mode Linux (UML) with an event-driven simulation engine and other instrumentation needed for deterministically controlling the flow of time as seen by the UML kernel and applications running under it. umlsim will be useful for a wide range of applications in research and kernel development, including simulations involving the networking(More)
Initially included exclusively on Intel®1 Itanium®2 platforms, the Extensible Firmware Interface Architecture (EFI) will soon be supported on IA-32 server, workstation, and desktop systems. This paper provides insight into the design and composition of an EFI enabled IA-32 Linux kernel capable of booting on legacy free platforms. An overview of the EFI(More)
