There must be quite a few Linux Athlon users out there - what boards are you using and with what success? I can't see much alternative to Via chipsets in the Ahtlon market, other than all-in-one-graphics-sound-network jobbies that, from previous experience (namely the i810), are also best avoided.

I have 17-18 MB/sec on my Quantum Fireball 6.4GB (5400 rpm) drive attached to UDMA33 and 14-15 MB/sec on another, also 5400 rpm (guess Samsung) drive. Both in -c1 -d1 -m16 mode.

Main point is that in many enviroments the niced processes are the ones the system exists for in the first place. I.e they are the most important ones. It would be completely unacceptable, say in research enviroment I know, if my computational job will be killed because somebody launches Netscape or some interactive game. The OS which does this is then will not be considered suitable for research. Niced processes are usually the most complex one organizationally, and quite often are fairly complex to launch (not just click a button on your Gnome panel). Moreover background niced processes by definition are typically run unattended so need to relaunch has yet to be detected. I, for example, typically lauch sequence of simulations simultaniously on 20 Alphas running Linux, which then run for 3-4 days. So yes, I do care that simulations are not killed after 5 minutes. because, first I have to notice this (or write and run monitoring program), second I have to find what was exactly run on this specific machine which was killed and so on. > > > > But if you put the logic "niced == not important" somewhere into > > the kernel, nobody will use nice anymore.

So the loss in terms of human hours is larger when it is killed. It shows quickly when you have some deadline to meet.Believe it is not pleasant to come in the morning and find the simulations you launched overnight disappeared. The day you planned on spending analysis the output results is gone. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] Please read the FAQ at http://www.tux.org/lkml/

Please don't, this assumption is quite wrong. I use nice just to be 'nice' to other users. I can run my *important* CPU hog simulation nice +10 in order to let other people get more CPU when the need it. In that case the time the process has been running and the CPU time used will save the process if it's been running for a long time. Please read the /entire/ algorithm before making rash conclusions like this. If nice is used for important, long-running tasks, the fact that they are long-running will save them (and be honest, would you really care if a simulation would be killed after 5 minutes? it's only inconvenient if it gets killed after a few hours...)

But if you put the logic "niced == not important" somewhere into the kernel, nobody will use nice anymore. I'd rather give a bonus to niced processes. This doesn't make ANY sense at all. The objective is to destroy the least amount of work, which means giving a bonus to processes which have used a lot of CPU time already ... regardless of nice value.
