SoylentNews is people

Cloud computing involves displacing data storage and processing from the user's computer on to remote servers. It can provide users with more storage space and computing power that they can then access from anywhere in the world rather than having to connect to a single desktop or other computer with its finite resources. However, some observers have raised concerns about the increased energy demands of sustaining distributed servers and having them up and running continuously, where an individual user's laptop might be shut down when it is not in use or the resources utilization of the server is less than the lower threshold, for instance.

Now, writing in the International Journal of Information Technology, Communications and Convergence, researchers at the University of Oran in Algeria, have investigated how cloud computing systems might be optimized for energy use and to reduce their carbon footprint. Jouhra Dad and Ghalem Belalem in the Department of Computer Science at Oran explain how they have developed an algorithm to control the virtual machines running on computers in a cloud environment so that energy use of the core central processing units (CPUs) and memory capacity (RAM as opposed to hard disk storage space) can be reduced as far as possible without affecting performance overall.

Unfortunately, there is little detailed information on the algorithm itself in the article.

I suspect some Soylents have home servers which they access from within their home as well as remotely. What, if anything, do you do to reduce your energy costs?

    Does that include 100% internet up-time? No router or modem restarts? No software updates or hardware upgrades? No fiddling with it because something needs tinkering? Assuming you aren't just pulling out a favorable metric, that is impressive. I've only gotten months of up-time out of my server due to power failures, and I have to spend more free-time than I'd like to keep rotating drives off-site. It adds up to a lot that most do not account for when having this discussion.

    Who gives a flying fuck about 5 9s?
    It's a personal website FFS?
    My god you are dense.

      "My uptime is the winning argument in this debate... oh, wait, no it's not all the sudden!" Smooth.
