We study several versions of the problem of generating triangular meshes for finite element
methods. We show how to triangulate a planar point set or polygonally bounded domain …

Cloud computing is a utility computing paradigm that has become a solid base for a wide
array of enterprise and end-user applications. Providers offer varying service portfolios that …

Modern" warehouse scale computers"(WSCs) continue to be embraced as homogeneous
computing platforms. However, due to frequent machine replacements and upgrades …

Energy consumption is a major and costly problem in data centers. A large fraction of this
energy goes to powering idle machines that are not doing any useful work. We identify two …

Server energy proportionality has been improving over the past several years. Many
components in a system, such as CPU, memory and disk, have been achieving good energy …
