Networking :: PQWFQ Scheduling Scheme Code In NS2
Nov 21, 2010I am doing a simulation on ns2 for diffserv. I am planning to use PQWFQ scheduling scheme for it. Where to find code for PQWFQ?

View 2 RepliesI am proposing moving from the mainframe to Linux. Problem is that I am not aware of a scheduling product that is available to handle the production code. Currently using CA7. Is there anything out there that accomplishes the same thing? As you can tell, I am NEW to Linux!
View 1 Replies View RelatedI have a linux box called worx. Worx has two LAN ports (built in to the mobo). LAN1 (eth0) connects to the network. LAN2 (eth1) connects to MIC, a microscope controller. MIC never accesses the network. I need to be able to use worx to talk to MIC but I don't have my setup correct. The problem I have started via a corrupted filesystem that resulted in a lot of broken packages, including the LAN adapter drivers. I reinstalled the LAN drivers and all the networking utilities. Both adapters can now be used to access the interent if configured with DHCP so there's no issue with the hardware. I need worx to be able to connect to the network on LAN1 and the MIC on LAN2. The MIC is an XP machine that is configured with a static IP (159.159.159.2 in this case). I feel like I should be able to do this myself but for some reason nothing I've tried has worked.

Can anyone tell me where i can find patch for WFQ scheduling in ns2
View 3 Replies View RelatedI have a Intel DH67CL motherboard with UEFI support(and updated to latest BIOS). I have connected a 180GB Intel 330 SSD into my system so as to install Debian testing.
Presently, a 160GB sata hard drive is connected along with SSD and is used to boot default OS.
1. I am planning to do GPT partitioning. I am totally new to GPT partitioning. from what I understands, It needs some mandatory partitions like ESP. My doubt is, in a SSD solely booting Linux, will I need to create separate /(root) and /home and /data partitions? Also, I plan to use /var/log and some other frequently updated directories moved into existing harddrive.
So, what is the partitioning order - is this fine - ESP(512MB), /boot(100MB), /(30GB), /home(50GB) and /DATA(50GB) and remaining 16-17GB for over provisioning for the SSD?
2. is there a need to have 128MB MSR(microsoft reserved) in the case of Linux
3. With gdisk or parted for creating partitions? how to verify if partitions are aligned. In GPT, only primary partitions are supported?
4. Some answers in askubuntu/superuser says ext4 is not really good for SSD, instead take JFS? is this true? Is Btrfs mature enough to use with Desktop system
5. Which bootloader? gdisk creator Roderick is pushing for rEFInd or gummyboot instead of GRUB2.
6. In my PC, 4GB RAM is available with a core i3 processor. Shall I mount /tmp in RAM? Will I need to specify the size of RAM when mounting using /etc/fstab? A size of 1GB is fine?
7. using deadline I/O Scheduler instead of CFQ?
I have several terminals opened at once to monitor the logs. It would be helpful to choose different basic color for text (and maybe for background) for each terminal so I can quickly locate the one I need. Anyone know how to do this or perhaps point me to right direction?

How the cron syntax can be written.
We are seeing some strange behavior on a Set top Box with the scheduling of tasks. We use 2.6.12 kernel. The issue is when we create a Task, say task1 with a priority of 46.But,this task is not Scheduled to run by the scheduler right away. It gets chance to run only after sometime. What we see here is that I create many other tasks with lower priority than task1,but they are immediately scheduled. Ideally, the task1 should have got scheduled before certain other low priority tasks as it has higher priority. Any patch is available wrt this?
View 3 Replies View RelatedI find system sounds distracting, so having recently installed F11 I've turned the sound theme to 'no sounds', which is fine. However, when I boot my system and get the GDM login screen, every time the password text input box gets focus, it emits a *really* loud low beep. I have no idea where to begin looking to customise the settings for GDM to disable all sounds.

View 6 Replies View RelatedI used to use the negative filter (Compiz) with Eclipse in order to have a dark background, but I wasn't satisfied. Then I ended up changing the Appeareance for all gnome windows (and applying a color scheme to Eclipse editors), so my background is black and the text is white.
It works perfectly for most of applications, but some (i.e. the crappy Celtx) are unreadable, as they keep the white of the font but use a white background. For Celtx, I'm still searching for the css to modify. But, overall, it could be great if there was a way to define one -more standard, black on white- color theme to be applied only on some applications (the conflictive ones).
I have installed Ubuntu 10.04 LTS on machine but wanted to choose RAID and LVM during partition scheme. Unfortunately I couldn't find such option during partitioning. Is it true that for Ubuntu 10.04 LTS it is unable to use RAID and LVM ?

View 2 Replies View RelatedI am wondering about scheduling audio playback under Ubuntu. The background is this: My birthday is fast approaching, and I always try to do something to remember the best birthday gift I ever received, that being the Apollo 11 mission; Neil and Buzz landed on my 12th birthday.
Anyway, I have a wagonload of audio from nasa.gov and would like to schedule the MP3s to play in real time. 'at' won't do it, at least with 'mplayer'; I've tried. I suspect that because there is no controlling terminal for jobs run under 'at', the audio has no place to go. Is there some way to get a controlling terminal for these audio playback jobs, or specify a destination to some player?
I can not get 'crontab' to work.Below is the results of 'crontab -e':

I was searching for many time but haven't found any solution. Cron would be great, but it allows only steps in range 1-59 minutes. Is there any mode to run something exactly every 73 minutes?
The second i need (the same problem) to run program little more than every 12 hours, it might be in steps of 12 hours and 4 minutes (but 13 hours is much too much).
i think we can simulate preemption by using 2 different priority thread, am i true? I just try these scenario :
1. Create Thread A with priority 99 , SCHED_FIFO..
2. Create Thread B with priority 4 , SCHED_FIFO
Thread A started and doing some busy work.. I guess that Thread B wouldn't start until thread A finished, but I get thread B can run before Thread A finished (It just like a common task switching).. I'm sure my 2 thread has right priority. and if thread B is doing some work and if i yield it to thread A, it should preempt it but this doesnt happen, do someone kno wats happening?
I have a program which is uses sigaction to register for a SIGIO signal (for incoming data on a fd) with an appropriate event handler. I also create a new detached thread 'B' that does some work with the received data. Normally the thread B runs properly. But when my event handler is called (because a there is new incoming data), after the event is handled, the thread B is not called immediately. There is a noticeable delay of the order of many seconds before it is scheduled again .During this delay, my program is doing nothing.
What am i doing wrong? Is there someway i can run thread B as soon as the event is handled (and assuming no other work is to be carried out)?
i want to do scheduling using /etc/crontab file instead of using crontab -e that is crontab command on the terminal.i am appending to the crontab file in the /etc directory but the scheduling is not happening
