"SCHED_DEADLINE is a new deadline-based real-time task scheduling policy for the Linux kernel with bandwidth isolation (aka "resource reservation") capabilities. It supports global/clustered multiprocessor scheduling through dynamic task migrations.

The scheduling class implements the real-time scheduling algorithm called Earliest Deadline First (EDF), one of the most common real-time scheduling algorithms."

Wed, 13 Feb 2013 18:25:00 GMT donotreply@osnews.com (project_2501) Comments patchset? http://www.osnews.com/thread?552357 http://www.osnews.com/thread?552357 It's been awhile since I heard of any patchset on more then less mainstream news.

Does anyone using one of these on purpose? I mean not because kernel packages comes with one or more preinstaled. The last one that I used was lck.

Deadline allows more parallelism, so more cores can be doing IO without having to wait for each other. It works especially well with XFS, which is also designed for highly parallel loads.

It has other benefits too but this is why I use it. Thu, 14 Feb 2013 04:10:00 GMT donotreply@osnews.com (foobaz) Comments RE[2]: how is this used? http://www.osnews.com/thread?552666 http://www.osnews.com/thread?552666 I think you are confusing I/O schedulers and process schedulers.

SCHED_DEADLINE is a process scheduler, for scheduling processes to run on CPUs.

The "deadline" scheduler you are talking about is the I/O scheduler which determines which processes can do I/O to the storage system.

Very different things! Fri, 15 Feb 2013 18:57:00 GMT donotreply@osnews.com (phoenix) Comments
