Using the Best CPU Available on Asymmetric Systems

Dietmar Eggemann posted a patch from Quentin Perret to take advantage of energy-efficient CPUs on asymmetric multiprocessor (AMP) systems. AMP is distinguished from SMP (symmetric multiprocessor) systems in that an SMP system uses several instances of only one type of CPU, while an AMP system might use CPUs of differing speeds, feature-sets and so on.

Quentin's patch was an effort to take advantage of differences in power consumption between the CPUs on an AMP system. It attempted to identify the most efficient CPU that was not already saturated with processes and assign newly awakened processes to it. If no CPUs fit the bill, standard SMP-type methods of processor assignment would be used instead.

FOSS Project Spotlight: Pydio Cells, an Enterprise-Focused File-Sharing Solution

Pydio Cells is a brand-new product focused on the needs of enterprises and large organizations, brought to you from the people who launched the concept of the open-source file sharing and synchronization solution in 2008. The concept behind Pydio Cells is challenging: to be to file sharing what Slack has been to chats—that is, a revolution in terms of the number of features, power and ease of use.

Minimum GCC Version Likely to Jump from 3.2 to 4.8

The question of the earliest GCC compiler version to support for building the Linux kernel comes up periodically. The ideal would be for Linux to compile under all GCC versions, because you never know what kind of system someone is running. Maybe their company's security team has to approve all software upgrades for their highly sensitive devices, and GCC is low on that list. Maybe they need to save as much space as possible, and recent versions of GCC are too big. There are all sorts of reasons why someone might be stuck with old software.
