Naturally, I didn't do any real time-line since 1991, but more of an "overview" if you will. You can see it here: http://benhamo.org/wp/?p=693 If you have any correction, comment or any useful tip, please add it to the talk backs so I can add it.

protection from runaway CPU-hogging process
still at the client with the VLSI tools. Some of the users here are running heavy simulations (all userspace, almost 0 kernel time), at times a single process can hog the entire system. I have no idea how that happens, as this is a fairly modern kernel (the slightly older scheduler of RHEL4's 2.6.9) and the Cadence tools are not using lightw×–ight procs, so all the load is on a single core (on a quad Xeon) and yet once it starts the whole machine is choked, and I can only hit the reset. step 1: I asked them all to nice down the jobs, but they are not very happy to. I'm trying to educate them and make them use wrappers (I'm introducing condor here anyway) step2: I have set up the root's .bashrc to renice me up to -4 and so I can keep a session active for the next time this happens and at least be able to run "top" and "kill" step3: I need a monitor to alert and maybe kill or renice such processes when they pop up and drag the machine down to a halt. till I find out who the culprit is, I don't have a procname and so "monit" is not a good choice. any other good ideas? step4: how do I log this without overlogging? some sort of a smart process auditing daemon? I don't want to improvise with shell scripts and cron, grepping from PS, because when the excrement impacts the venta it may not be able to run (unless I hike the crond's priority to a negative nice). I need a small reliable C proggy to do the right thing. the obvious is maybe to set some ulimits on the users, but I don't want to limit heavy processes that do NOT choke the system. -- A meal best served cold Ira Abramov http://ira.abramov.org/email/ = To unsubscribe, send mail to [EMAIL PROTECTED] with the word "unsubscribe" in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]
Re: QoS question
I have 1.5Mbps dl and 128 kbps up. This is the only Qos they apply on me? Can you send a link where it's written that 012 was caught with rewriting actual bitorrent packets?

Re: protection from runaway CPU-hogging process
Hi, If it is not the processes maybe it is the harddisk/filesystem ? Log files being written by multiple users to different files can have a harsh effect on the performance of the operating system if the harddisk isn't up to it. As I recall from my university sessions :) Cadence tends to write hundreds of small files, and then bind them all into one big simulation file, not sure if it is tweakable - I wasn't the admin back then :) On Tuesday 10 June 2008 20:14:27 Ira Abramov wrote: > still at the client with the VLSI tools.

BUT that said - we were virtually forced to use CentOS for the hosted servers and I prefer to "break my teeth" on one distro than: 1. Have to learn it anyway for some servers but still maintain scripts/codebase for multiple distros. 2. Have to teach my employees and colleagues about the difference between distros 3. Have to justify to my superiors sticking to yet another distro besides the one we have to use on servers.

Ira - you've been a long time in this field and I expect you should have the experience to see, in retrospect, that many things which looked "weird" and "overblown" and "who needs this?" and "the old way works, why break it?" (gnome vs. KDE vs. Xaw, grub vs. lilo vs. syslinux, cups vs. lp vs. lpr, LVS vs. partitions, GUI web browsers vs. command line and TUI ftp clients, JavaScript, etc) became standard and we got used to them and learned to appreciate their added value. I'm probably just as familiar with the new init process as you are (I just overheard they plan to use something instead of the traditional init) but I guess that it'll either become usable and stick or otherwise will drop off the face of the earth.
