Real-Time Scheduling

Falcata · 2008-04-04 20:42:57

I've heard of some stuff going on in the kernel development, referred to as "real-time scheduling." Could someone tell me what it is, and what it's benefits are? I've been having a hard time finding information on it.

See wiki.

That took me about 0.05 seconds of googling

RT Scheduling is going to be interesting when it comes out. It looks promising :-)

Well, I guess it won't really make a difference for us desktop users. We are simply unable to notice a difference between low-latency (1/1000th second timer) desktop and an (almost) real time os. It can, however, have a negative influence on data throughput, so I'm less excited about it.

Note to self: drink coffee prior to doing anything on the computer. Or caffeinated cereal.

I'm pretty sure, for the typical desktop user, there isn't anything to benefit from. Hell, there are even downsides to it if we're talking about sched_rt for a desktop OS carrying out desktop tasks.

... there's serious interest in running RT tasks on enterprise-class hardware ...

It's already there. It is just expected to be (greatly) improved in 2.6.25.
