As in window we normally use task manager (ctrl+alt+del) to see how many tasks are currently runing in the window ..similarly please give me alternative of this linux . that is how to know how many sottwares are running in linux is there any terminal commands for this or shorcuts keys as window.
View 3 RepliesI'd like to get the information about automatization of the tasks in Linux, more specifically in Fedora with minimal installation (without graphical interface and so on).The application (developed in C) needs to be started automatically when the computer is initialized. I've read about cron but I guess it's not a solution in this case because whenever computer starts the application must run once.I also have read about the/etc/ rc.local file but I made some tests changing it and they didn't work, the computer starts asking me the login and password but nothing run after that.The inittab was the same. In this way, someone know how to initialize an application developed in C when the computer starts?
View 6 Replies View RelatedI have a script which basically does many tasks and most of them can run in parallel. The server it runs on has 4 cores, so I changed parts of it to a makefile, and then run them with "make -j 4" which helps a lot. But looking at "top" while it runs, I see it could be improved. Sometimes tasks wait for other servers, so a higher -j value would help. And sometimes multiple tasks are waiting on the same disk, then I think a lower -j value would be better.
The kernel is fairly good at sharing CPU time among the cores, but resources like memory and disks are not shared very well. As an experiment, I tried compiling the kernel with "make -j" with no number. It didn't go very well.
So I wondered if anybody know of a better tool for things like this. I think it should be possible to write something that could change the -j value while it runs.For example:
- Start as many tasks in the background as there are cores. When tasks finish, start another one until done.
- After a little while, check CPU and memory usage to decide if more tasks could run in parallel. Or maybe less?
- If different tasks iowait a lot, check if they wait on the same disk. If so, renice/ionice/suspend some of them. In these situations I think it's better to have them run one after another.
- Other ideas?
I thought of making a script like that, but I doubt I'm the first one with that problem. Also, there are probably lots of things I haven't thought of.

View 3 Replies View RelatedI am in the process of running a set of performance tests for the latest Sun JVM 1.6.0_20. I am using for that the dacapo test suite: [URL]
I ran the test suite very often with all sorts of settings, but recently it happened once that my Ubuntu system froze. I could still ping the machine, but nothing else was responding any more, no screen output, no ssh login, not possible to switch consoles. After rebooting the system the system logs were quiet. No single trace of any problem.
I am using a custom compiled kernel 2.6.34: Linux i7 2.6.34-custom-201005231602 #1 SMP PREEMPT Sun May 23 16:06:01 CEST 2010 x86_64 GNU/Linux and I am experimenting around with the -XX:+UseLargePages JVM switch the requires to set-up the hugetlbfs on the Linux system: [URL]
A similar issue happened in March 2010 on one of our CentOS 5.4 systems where we run a heavy load Java application on, where we had to hard power off the machine and after the reboot there was no trace of the problem in the logs. On that server we used JDK 1.6.0_17 and did not use hugetlbfs.
My first question would be what to do so that next time something like that happens I have more information available after the incident to debug and analyse the problem?

View 2 Replies View RelatedAssume I`m a newbie and I want to run two CPU-consuming tasks but with different priorities - I mean one to get more CPU time that the other. How to achieve this in Fedora?
View 14 Replies View RelatedWe 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 Relatedfor the past several months now, whenever the YUM-deamon goes to automatically update, it just says "waiting for other tasks" and after about 10 min it says "can't get yum lock, other program accessing yum" or something to that effect.i get the same message if i try to manually install programs using the graphical program in gNu.
is there another deamon that also could be using yum or the database for programs? i haven't had too much time to trouble shoot the past few months, so i can't give you better descriptions i'm afraid.

Recently installed 10.10 netbook edition, and evolution is behaving strangely. Albeit I've never used it before, but having read the documentation and googled it a bit I'm still lost. I cannot create or manage task lists. It's as if their functionality has been completely cut out of ev calendar. When I try to go to File->New->Task List, the Task list option does not appear in the menu (not greyed out, nothing). Can't find the button that's supposed to be there either. I've also checked synaptic for evolution task packages, but no avail.

View 2 Replies View RelatedI'm using Evolution in Gnome 3 and I'm having this rather annoying issue---whenever I make a new Task, it does NOT show up in the Tasks bar. Even if I try searching for it, the task doesn't show up (even making a new Task List doesn't show up), which makes me think it was never saved properly in the first place. I also tried seeing if there was any sort of error while running Evolution by opening it via the terminal, but I don't get anything. Does anyone else have this issue? Is this a known bug with Evolution
View 2 Replies View RelatedYesterday, I found that the majority of my tasks on Evolution (2.28.3) had just disappeared. I last did a backup of my system 2 weeks ago but in that time important data has been added to my tasks lists on Evolution. I've read around and found that the problem may be fixed by rebuilding evolution-data-server (see here). However, if this means re-compiling evolution-data-server from the package manager, well, I don't seem to keen on doing that unless I can get confirmation of how to implement it, i.e. how do I rebuild evolution-data-server?

View 5 Replies View RelatedOver the past few days, I've noticed that administrative tasks sometimes fail to start. I'm asked to enter the administrative password, "Granting rights" appears in the bottom panel for a few seconds, but then disappears. I'm using Debian Lenny. This is only an intermittent problem, and if a task does fail to start, it will start on the next attempt. Tasks which have failed to start are:
*Launching Synaptic form the System menu.
*Launching a root terminal from the Applications menu.
*Launching Nautilus with root privileges from a terminal using gksu.
After coming across the following post, I thought maybe it was an issue with kernel 2.6.32-bpo.5-686, because I'd recently upgraded to that kernel too, but I'm advised that that isn't so.It was suggested that something else from backports might be causing the problem.
