Linux: CFS Group Level Fairness

Following a review of Ingo Molnar's Completely Fair Scheduler, Srivatsa Vaddagiri posted a patch allowing the new scheduler to provide fairness at a per-group level rather than at a per-process level. He described the changes that he made and noted,"I have used'uid' as the basis of grouping for timebeing (since that grouping concept is already in mainline today). The patch can be adapted to a moregeneric process grouping mechanism later."Ingo reacted to the patch favorably,"yeah, i like this alot." He went on to comment,"the'struct sched_entity' abstraction looks very clean, and that's the main thing that matters: it allows for a design that will only cost us performance if group scheduling is desired."

ASUS P5N-E SLI on Linux

The ASUS P5N-E SLI motherboard rings in at about $130 USD, which makes it substantially cheaper than many of the NVIDIA nForce 680i SLI motherboards on the market and even some of the nForce 650i motherboards. While this motherboard may be affordable, does it deliver upon the ASUS quality and innovations that enthusiasts have come to expect from their cutting edge products?

Breakin' It Down

There has been some strong negativity in some of the articles and more than a few responses lately. With Dell tilting and twirling on the Linux machine line of products and Microsoft playing the ever-present boogie man, there has been much on the minus side of the ledger for us to chew on.

  • Story Type: Editorial

We need to de-legitimize both messenger and the message.

This week at LWN: A day at the Open Source Business Conference

LWN readers will certainly be aware that your editor spends a fair amount of time at development-oriented conferences. In some ways all conferences are alike, but, still, all that experience was insufficient to prepare your editor for OSBC, which is a different sort of affair. Neckties, Blackberries, and Windows laptops are ubiquitous. There are booths for law firms. People wonder about whether customers should buy their "open source" software licenses on a one-time or subscription basis. The wireless network actually works, but power outlets are nowhere to be found. It's all very strange
