I've somehow got it into my head that it's possible to share CPU cycles, though I've no idea where from.So basically that's what I'm asking - is it actually possible to tell one system to 'donate' it's unused CPU time, cycles, whatever they are, for another's use?

View 1 Replies View RelatedJust trying to figure out some stuff with a broken process. A java app seems to sometime get stuck on a loop or something and i'm trying to find out what's causing it using just the following #sysadmin tools at my disposal.
Things like:- htop - find the PID thats causing the High CPU cycles. I'd then want to use /proc/[PID] or lsof -p [PID] or strace [PID] etc. But the PID doesn't exist in 'ps -ef' output so I think htop must be showing me kernel level thread PIDs?
Not sure about the PID's HTOP is actually giving me? I know that some of them are the real PID's that can be accessed through /proc/[pid] etc but others are not but are i assume child processes or more likely threads as child processes are normally shown in a default ps output anyway.
Is someone able to help distinguish to me about what exactly all these other PID's are that I can't manipulate or find apart from when using HTOP.
I have a machine running Fedora 14 and a bunch of movies stored on it as '.iso' images. It is connected to my home theater. I used to use VLC to play these movies and it worked great for a long time. About 4 months ago, about an hour or hour-and-a-half into a movie, the audio suddenly "disappears" and the machine goes CRAZY with almost 100% of the CPU spent writing to the SWAP. At first I thought the machine was locked, but it isn't; it's so doggone busy writing swap. I am unable to get enough cycles to terminate anything. I found the swap activity through System Monitor - it was ABRUPT. Sound stopped, machine became preoccupied with swap.
I have removed/reinstalled VLC, the machine has undergone a couple kernel updates, and I have removed/reinstalled a number of things associated with audio (CD ripper, mpeg stuff, etc.) yet the problem persists. I don't know what happened or when (update-wise). Any body got any ideas? While a solution would be great, I'd also be happy with a couple decent suggestions on what to look for.
Never seen this happen before. I'm using the blank screen saver.

I have a couple of question regarding the screen blanker on Gnome desktop.I used to use a 1024x768 display with previous openSUSE distribution. With 11.3, I discovered the new "auto-configure" X feature. The default screen mode was 1600x1200, but I changed it to 1280x1024.My gfx board is a Matrox G400 DH. Hardware acceleration is disable because of a missing mga_dri.so (fall back to software rendering).I find some screen blanker modules are using almost all the CPU cycles. Animations are very slow, and it can take long before a keyboard hit or mouse movement makes to leave the blanker.
So the questions:- Is there a way to define another (smaller) screen resolution just for the blanker ?- Who should I try to convince to add mga_dri.so back in Mesa again ?- When the monitor go to sleep (DPMS), the blanker still is running, uselessly consuming CPU times. (I can see that because at the first mouse/kbd event, the monitor wake up and shows the blanker running.) Is there a way to configure the blanker to stop running when the monitor is sleeping ?- There are some modules which load images from HD (not the diaporama which load images in ~/images). But the shown image is always the default built-in one. Where is the blanker trying to load images from ?
I am running open suse 11.3 and keep up on maintenance. Ever since upgrading to 11.3 I find that the number of cpu cycles is being eaten for apparently nothing. In looking at the system monitor I frequently find that Xorg is using 24% and frequently more than that. What can be done to reduce the cpu cycles, or fix the problem?

View 2 Replies View RelatedI was running 10.04 until yesterday, when it occured to me that I could upgrade to 10.10. So I went to Software Center, set it to get normal releases and left it to do its job. The upgrade appeared to go without a hitch and I rebooted. The login screen appeared. But just before I could click on my username and enter my password, the screen went blank and a second later the login screen was back. But then just before I could click... Undeterred, after half a minute of frantic clicking I did manage to click on my username and get the password prompt. This time, the login screen didn't go anywhere. Yay. To cut a long story short, this is now my standard logon procedure. However, the plot thickens. I appears that instead of 10.10, I ended up with 11.04, Natty Narwhal, which 'was released in April 2011'. If I download an .iso of Maverick and install it over my current version, will it leave my data unharmed AND reset everything so that it works again?
View 5 Replies View RelatedI've been struggling with suspend to disk (hibernate if you prefer) for a while, it works after a fresh boot and for several days' worth of overnight hibernation as I go about my work, but eventually it stops working - it gets to the splash screen but the bar only makes it a little way to the left before stopping, and then after a timeout the system just returns to the "session locked" screen - no real error messages.
I've done my best to try to find out what's causing it to break but I'm really struggling, the suspend process doesn't appear to write anything helpful to the dmesg log or the /var/log/pm-suspend.log - the only thing that I've seen at about the right point in time is cifsd, but I can't be sure that it's a problem with cifs as hibernate continues to work immediately after mounting windows shares with cifs.

I have a problem in Ubuntu 10.04. The bug is well know which makes the hard disk head to park often (2-3 times per minute) that's dangerous for the drive in the long term and annoying for me (click-click-click).I found out the "ugly-fix" for old Ubuntu version which was :hdparm -B 254 /dev/sda instead of 128. It works. The problem is that it doesn't remains (when restart/standby/ac connection-disconnection).I found a script well known too :Code:1) make a file named "99-hdd-spin-fix.sh". The important thing is starting with "99".2) make sure the file contains the following 2 lines (fix it if you have PATA HDD):
#!/bin/sh
hdparm -B 255 /dev/sda

View 2 Replies View RelatedIs the mount point for external media (like USB) always /media?
Because in a Debian system, if I plug in any USB device that goes to the /media folder. So is it the case with all the other Linux flavors like Fedora, Ubuntu, etc. If a USB device is automatically mounted will it always go to the /media directory?
I am not concerned about the name of the devices. I am looking for every external media (like USB) to be listed under /media directory so that my code can run on any flavor of Linux.

View 2 Replies View RelatedCan anyone suggest a product that will allow a developer to raise a ticket (or similar sort of trackable item) which can be used to track the progress of a software build through a number of environments?Basically It's just a case of creating a ticket, using that to trigger a software build, then requiring some form of sign off to allow a second stage, and then another sign off for a third. It's not about building things, just tracking an issue through various stages of testing through to production.
I'm looking at replacing an environment which currently uses jira for this purpose, but I've no knowledge of it, and am keen on other GPL tools instead. Jira is, as a product, massively overkill for what is required too. So I'm keen on one which might fit in with the rest of my toolset - cobbler, func, puppet etc. I was looking at trac, which seems like it might have some relevant angles to it, but I really can't tell because having not done this sort of project before I don't honestly know what to call what i'm after. I don't *think* that something like bugzilla would be appropriate as it's too specifically about bug tracking, rather than a generic workflow with signoff stages and such.
