Linux A new version of the real-time Linux scheduler called SCHED_DEADLINE has been released on the Linux Kernel Mailing List. For people who missed previous submissions, it consists of a new deadline-based CPU scheduler for the Linux kernel with bandwidth isolation (resource reservation) capabilities. It supports global/clustered multiprocessor scheduling through dynamic task migrations. This new version takes into account previous comments/suggestions and is aligned to the latest mainline kernel. A video about SCHED_DEADLINE is also available on YouTube.

Laurence,

"Well yeah, that's what i just said."

"Interesting concept. A little tricky to impliment I think, but it has potential."

Maybe we're misunderstanding each other, but the OOM killer I described above *is* what linux has implemented. When it's enabled (I think by default), it does not necessarily kill the requesting application, it heuristically selects a process to kill.


"The only 'safe' option would be to set everyone up with thin clients which only have a web browser installed and bookmarked link to cloud services like Google Docs."

Haha, I hear you there, but ironically I consider firefox to be one of the guilty apps. I often have to kill it as it reaches 500MB after a week of fairly routine use. I'm the only one on this computer, but if there were 4 or 5 of us it'd be a problem.


This is probably hopeless, but here is what top prints out now:

PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
27407 lou 20 0 1106m 403m 24m R 4 10.0 50:27.51 firefox
21276 lou 20 0 441m 129m 5420 S 3 3.2 869:47.14 skype

I didn't realise skype was such a hog!
