Intel dreams of draining Linux power
Intel has launched an effort called LessWatts.org on Thursday, a combination of open-source software and helpful hints to reduce power consumption of Linux servers, PCs and gadgets.
LessWatts is geared toward technically sophisticated folks from programmers to system administrators. It gathers together a number of Intel projects, such as the PowerTop utility for finding which software is pestering the processor and preventing it from dozing in low-power states. Taking Intel's advice and fixes can trim about 10 watts of power consumption off a modern dual-processor server, said Dirk Hohndel, chief technologist of Intel open-source technology centre.
That's not a gargantuan amount -- until you consider that if done correctly it's free power savings, that each watt of server energy saved cuts another 1.3 watts from air conditioning (according to Intel figures), and of course that 10 watts per server is a lot when multiplied by the thousands of servers that populate larger data centers.

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
