Entropy: a consolidation manager for clusters
TL;DR: The Entropy resource manager for homogeneous clusters is proposed, which performs dynamic consolidation based on constraint programming and takes migration overhead into account and the use of constraint programming allows Entropy to find mappings of tasks to nodes that are better than those found by heuristics based on local optimizations.

Documenting and automating collateral evolutions in linux device drivers
TL;DR: This paper presents an automatic program transformation tool Coccinelle, for documenting and automating device driver collateral evolutions, and uses a language based on the patch syntax to express transformations, extending patches to semantic patches.
Proceedings ArticleDOI
Faults in linux: ten years later
TL;DR: It is found that Linux has more than doubled in size during this period, but that the number of faults per line of code has been decreasing, and even though drivers still accounts for a large part of the kernel code and contains the most faults, its fault rate is now below that of other directories, such as arch (HAL) and fs (file systems).

Think: A Software Framework for Component-based Operating System Kernels
TL;DR: Performance measurements show no degradation due to componentization and the systematic use of the binding framework, and that application-specific kernels can achieve speed-ups over standard general-purpose operating systems such as Linux.

Identifying Linux bug fixing patches
Yuan Tian,Julia Lawall,David Lo +2 more
TL;DR: This paper proposes an approach that automatically identifies bug fixing patches based on the changes and commit messages recorded in code repositories, and compares it with the keyword-based approach for identifying bug-fixing patches used in the literature.
