CentOS 5 :: Set Default Affinity To CPU 0?
Dec 18, 2009I have a question about using taskset. I am using Core 2 Quad box. I set the default affinity to CPU 0, by doing the following:
Edit: /etc/rc.d/rc.sysinit
Addline: /bin/taskset -p 1 0
That has been working fine for me, but from searching the web, I found some suggestion about adding an additional line:
/bin/taskset -p 1 $$
What does that line do?
I checked the man page of taskset and some references for regular expression, and I couldn't find the explanation about the $ character. By the way, 0 for CPU 0, correct? I checked via htop and seemed to be correct...
Ubuntu :: Program Execution Time And Processor Affinity?
Aug 7, 2010I have some questions.First, how can i obtain a process execution time ( after it terminated)??? Second, in a multi-core system like SMP how can i run different processes on different cores explicitly? i.e. how can i assign a process to a specific core?

Oct 28, 2009Does anyone know if there is a way to "unset" processor affinity? So if you bind a process to just one proc, but then want to tell the OS to revert to normal behavior? Also, when you bind a process to a processor, can other processes use that process or does it have exclusive usage of that proc?

Apr 29, 2010I am using glib version 1.2.10.I came to know from somewhere that "pthread_attr_setaffinity_np(3)" does not work on this version for POSIX threads. Following error was coming:(.text+0x112): undefined reference to `pthread_attr_setaffinity_np'collect2: ld returned 1 exit status.All I want to do is to run 2 threads on two different processors. I cannot change the glib version.

Oct 27, 2010Am investigating processor affinity theory and practice, am somewhat surprised at the paucity of information on something that has been a part of many Windows Enterprise type applications for more than a decade and although I haven't investigated would assume is supported by big iron UNIX.What it is Processor Affinity is the *NIX terminology for "soft" assigning a process and its threads to a specific processor core. On multi-tasking machines and particularly those which run heavy loads it can be useful to "advise" the Scheduler to isolate/assign heavy loads to a core separate from other processes. I also have a specific situation where I would like to run more than one instance of a specific app, but cannot when sharing the same processing environment.
What I've found so far By default, any and all processes are assigned an affinity that permits running on any and all available processors.The taskset utility can be used to modify the affinity for any process, which means that once an application/service/process has been launched, only then can the affinity be modified.It seems that the RH platform may also have a utility called tuna which might provide some tuning capabilities in addition to setting affinity but does not seem to be in the SuSE repositories and I cannot find source.Is there a reference or utility that can launch an application with a specified processor affinity?
Programming :: Setting Processor Affinity In Application
Jan 28, 2010there is any possibility that I can set in this application an affinity so that the processor binds it to core 2 for instance.Is this possible to do in an application that runs than under root? Or is this just possible after the application started with using the taskset tool?

View 1 Replies View RelatedUbuntu :: Wireless Does Not Work + Printer Drivers So Buggy + MP3 Players And Digital Cameras Not Work?
Jul 7, 2010I wanted some input on chronic problems with Ubuntu:
1. Why does wireless almost never work right on Ubuntu?
2. Why, when Ubuntu just decides to turn off my wireless card, can I not just turn it back on?
3. Why do tar balls almost never unpack right?
4. Why are printer drivers so buggy?
5. Why do my MP3 players and digital cameras not work with Ubuntu?
I spent 3 hours last night trying to unpack a tar.bz2 file so I can run my Ralink network card. It worked fine until my son unplugged my computer. Now my card is disconnected and it will not reconnect. When I check forums no one has a simple answer for something as simple as turning a network card back on. On my Apple, it's simple: click my wireless icon and hit "on." tell me an easy way to just turn my wireless card back on, it would renew my faith a little in Linux.
Ubuntu Multimedia :: Skype - Pulseaudio - Sound Output Or Input Does Not Work At All Doesn't Work
Sep 11, 2010When I installed my 64 bit system of Ubuntu 10.04 the sound worked very well and I were very happy. The problem started however when I installed Skype which uses pulseaudio. As soon as I start skype (or any other application that uses pulse, HoN for example) the applications sound output or input does not work at all. If I have pulseaudio started in some way, applications that I suppose do not use it like spotify or flash player stops to produce sounds. And when I type "pulseaudio" in the terminal it gives me this:

Ubuntu Servers :: Get Sobdomains To Work Fine On A Test Mache, But Domain/site To Work Due To Lack Of DNS Support At The Moment?
Feb 6, 2011I'm not to sure this is the place I should post this, but couldn't find any place for it to fit. So here is the deal..I am running 10.10 with the standard LAMP setup. I am running a drupal 7 site no problems. What I need to do is run a multi site sub directory. (domain.com/newsite). So far the best I can do is get a directory index of the second site (domain.com/newsite), but cant run the installer. (I did the symbolic link to the doc root of the drupal install.)If I type in the url domain.com/newsite/install.php I get not found. I placed an index.html test page and it renders fine. I think I'm close but just not there yet.
Any ideas from anyone? I can get Sobdomains to work fine on a test mache, but sadly I need the domain/site to work due to lack of DNS support at the moment. I tried to get some info from the drupal forum, but everything always points to subdomin setups. I also posted over there, but it seems like the forums have very little support and are a bit on the slow side.

Ubuntu :: Compiz Doesn't Work - How To Make It Work
Jul 29, 2010I'm having trouble getting compiz to work on my Laptop. It worked for a while and then I turned on Shift Switcher and a message popped up saying..."The new value for the button binding for the action Terminate in plugin Shift Switcher conflicts with the action Zoom Window of the Scale Addons plugin. Do you wish to disable Zoom Window in the Scale Addons plugin?" I was given the option of Set Terminate anyway, Don't set Terminate, and Disable Zoom Window. I clicked Don't set Terminate and ever since the only thing that works in compiz are the bindings in the general options. I've used synaptic to completely remove and then reinstall compiz but the problem persist. Something else weird, all of the changes I made are still there, even after complete removal, but they don't work?

Feb 16, 2011I just recently (about an hour ago) installed Ubuntu Netbook edition on my old laptop, and I was greeted with the message, that unity could not be run due to some sort of missing driver...fair enough, I was then greeted with the default Ubuntu desktop, I installed all my needed software (wine, google chrome) and installed the missing display drivers. I then rebooted the system, and once again I am stuck with the default desktop, and not the Unity interface. I checked the software center, and it says Unity IS in fact installed.. And yet I cannot make it appear. So now I ask you Ubuntu veterans. How do I make it work?
P.S. I wiped the system of windows, and the computer is an old HP Pavilion DV6000

Jan 12, 2011I am trying to set up an unused machine as a web server for my students.
I originaly tried with Redhat 9 and had the same problems. I am using an HP Pentium 4 system with 2 network cards.
1) The built in Realtek RTL8139 configured as eth0.
2) An add in Broadcom BCM5782 Gigabit card that was added I presume when the built in card failed (we have a number of machines like this around the school), configured as eth1.
I did not realize the second card was installed when I had Red hat 9 on the system, but I discovered it after installing centos 5.5. I have tried to configure the system to use DHCP with and without getting the DNS from the provider, and both ways the system complains that there is no connection, check the cable, so it will not activate the device.
When I configure the device to use a fixed IP, I can configure the device, but I can't ping anything on the network other than myself. I suppose it is possible that both network cards have failed, but I get green link lights with both cards, when I connect them to my router, so I am at a loss as to why neither board seems to work. I don't have a spare network card to slide in because the computer takes a special mini card. Is there an easy way to test the board to see if the board is a problem?
