How to remove the cpu usage limit?

I have to run a C program on terminal as fast as possible. However, there seems to be a cpu usage limit for the terminal, the program supose to run around 15 seconds on a linux machine with similar configuration where cpu usage is at 85-95%. But, it runs one minute on my macbook pro with cpu usage less than 15%. Finally, my question is, how do I utilize all of the 85% idle cpu for this program or at least most of the idle cpu?

Per se, MacOS X does not impose any CPU usage limits other than those from the processor scheduling priorities. Standard Unix scheduling priorities go from -20 to +20, with the default being 0. If you have administrator privileges, you increase your process' priority (a more negative value) with the nice or renice commands. See their man pages. On a four-core 15" or 17" MBP, even setting max -20 priority should not impact the rest of the system too much.
You may also want to go over and discuss these things in the Unix forums:

How to Remove the Entity usage from View object at runtime

Hi,
A ViewObject can be created dynamically based on the Existing ViewObject Defintions. The newly created dynamic ViewObject will have all the defintion including Attributes, its structure along wtih Entity usage of the existing ViewObject definition.
My requirement is i don't want to have the Entity usage alone whereas Remaining structure need to be retained.
Can any body suggest on how to do it.
regards.

Hi,
design time or runtime? At designtime, have you tried to just remove the entity reference? Given the disadvantage of removing the entity (and the changed behavior associated with it) what is the use case for which you want to disable the entity reference?

How to lower the CPU usage level?

My CPU usage level has always been over 90% even after i restart my mac book pro, what should i do?

You can launch activity monitor to see what processes are using what amount of CPU. Also there is an application called AppTamer it is a sharware program and has gotten good reviews. It helps to reduce CPU usage on programs that are kind of in the background, one's you're not using at the moment. I would also recommend iStats Menu which monitors are the vital systems, memory, cpu, temps, disk activity etc...if you don't want to pay for the license the dashboard widget iStats Pro is free of charge and does the same thing. Do you have a lot of apps starting as login items? Hope this helps. Follow up and let us know how things are working.

How do you get the CPU Usage in Linux

This is a link of an example in WIN32:
http://www.javaworld.com/javaworld/javaqa/2002-11/01-qa-1108-cpu.html
It notes that UNIX environments should use getrusage(), and that is all it says in regards to UNIX. The code I have attempted to use looks like this:
#include <sys/resource.h>
#include <sys/time.h>
#include "CPU.h"
#include "jawt_md.h"
#include "jawt.h"
struct rusage usage;
int ret;
struct timeval val;
struct timeval val2;
JNIEXPORT jlong JNICALL Java_CPU_getProcessCPUTime (JNIEnv * env, jclass cls)
   ret = getrusage(RUSAGE_SELF,&usage);
   val = usage.ru_stime;
   val2 = usage.ru_utime;
   return val2.tv_usec;
}My problm is that I don't think it is right...since the value returned is always the same no matter what the CPU usage is. same for if I used val instead of val2.
Any Ideas?

In Linux, you can read /proc/uptime. It does NOT give you the load averages that the command uptime gives. It gives you numerically the amount of time the CPU was idle vs how much time it was spent doing something. You need to read these two floating point numbers one every second, or once every 5 or 10 seconds then do the delta on the change: The maths are as follows:
Read the file in twice in 5 seconds, parse into two floats/doubles:
double[] last; // the first read of the file
double[] rect; // the latest read of the file
double ld = last[1] - last[0];
double rd = rect[1] - rect[0];
double cpu = (1.0d-(rd/ld)) * 100.0d;This should print the CPU percentage in Linux for that given time frame (5 second updates).

Can anybody help me to understand the CPU usage logs

Hello community,
I try to find the faulty machine in our network, but I don`t understand the logfiles. We have many servers which normally work very fast and reliable.
But sometimes we have such a huge cpu usage drain on our server. Nobody knows where it comes from, so I looked in the vsphere web client and looked in the cpu usage logs.
Following you can see two pictures. One is from the main host. It shows only a cpu usage of a maximum of 45 %.
When I look on the vmware machines I can see a cpu usage of more than 150%.
This is something I completely not understand. How is it possible that the main host machine has only a 45% cpu usage and the clients are exploding?
I don`t have set a cpu usage limit in our resource pool.
The next thing is. When I look on the vmmachines, I can not identify the faulty machine. Because when one machine increases the cpu usage many others increase too. Whatever why.
Can somebody explain me the pictures below please:
Thank you for your time
Paul

You don't have any need to understand this code. The complication is due to the registry needing a fixed objectID.
You just need to know the methods of java.rmi.registry.LocateRegistry class. This allows you to start an RMI Registry inside your JVM and give it any TCP port number you like.

Methods to reduce the CPU Usage for painting the image

Hi,
I have developed an application to view images from an IP camera. By this I can simualtaneously view images from about 25 cameras. The problem is that the CPU Usage increases as the no of player increases. My Player is JPanel. which continuously paints the images from camera. The method 'paintImage' is called from another thread's run method. This thread is responsible for taking jpeg images from IP camera.
Here is the code for this.
public void paintImage(Image image, int fps) {
try {
int width = this.getWidth();
addToBuffer(image);
currentImage = image;
Graphics graphics = this.getGraphics();
if (isRunning && graphics != null) {
   graphics.drawImage(image, 0, 0, getWidth(), getHeight(), this);
   if(border ==true){
    graphics.setColor(Color.RED);
                      graphics.drawRect(0,0,getWidth()-1, getHeight()-1);
   graphics.setColor(Color.white);
   graphics.setFont(new Font("verdana", Font.ITALIC, 12));
   graphics.drawString("FPS : " + fps, width-60, 13);
   this.fps = fps;
   if (isRandomRecord) {
    graphics.setColor(new Color(0, 255, 0));
    graphics.fillArc((getWidth() - 10), 5, 10, 10, 0, 360);
} catch (Exception e) {
e.printStackTrace();
Can someone please help me to solve this problem so that the CPU usage can be reduced.

Can you give me more detail information about how to use
an automated profiling tool You run it and excercise your app. Then it presents stats on number of times each method was called and time spent in each method, plus other stuff. Using those two stats you can zero in on the areas that are most likely to yield resullts.

NI HyperTrend Control raises the CPU usage of NI Citadel DB and freezes it.

When a VI uses NI HyperTrend Control to fetch data from NI Citadel DB, the CPU usage of citadel is raised up to 10% and stops working.
I don't know what "stops working" means since my coworker told me so.
How can the control be prevented from freezing citadel?

Best,
1) Does the Trace VIEW in MAX work?
yes with 3 signals(traces?)
2) What version of LabVIEW are you running?
9.0 SP1

yes
5) And he has another question.
Please refer to the attached image.
For now, if he wants to put Va/Vb/Vc in Y axis of a hyper trend control, he has to do it in the front panel.
He wants to put it in Y-axis via a property node in the block diagram.
Is it possible?

Why is the CPU usage different ? I used LOAD_BALANCE option.

I used a oracle 11.2.0.2 in RAC 2 nodes.
And I used LOAD_BALANCE option in the WAS pool configuration
jdbc:oracle:thin:@(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.10.118)(PORT=1522))(*LOAD_BALANCE=YES*)(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=NOFFICE)))
But the CPU usage is different between two system. Usually it is 6:4, Sometimes it is 7:3.
Is it normal?
I want to a balance in CPU Usage (5:5).
If it is the better solution about a Load balance. i want to know it.

You are partially correct which is another way of saying you are incorrect too.
There are two types of load balancing ... server side and client side. There are also questions with respect to how the client is connecting, we don't know, whether the session load is identical, etc. which the OP has not stated.
The only thing I can absolutely say at this point is that what the OP has seen is normal and I can't see any reason why, unless the skew is very large and very permanent, anyone should care.
To the OP: Let's step back from the "what I want" statement and go to the basis of your inquiry: "Why do you care? Please provide a business reason and cite specific performance metrics, from your system, showing the problem you are trying to address. Then perhaps we can help you.

How to remove the Object from memory.

Hello.
Flash file that i made with Flex Builder uses memory too
much.
Look at the next example source code.
var testCan:Canvas = new Canvas();
this.addChild(testCan);
this.removeChild(testCan);
testCan = null;
but just memory usage still goes up, is not freed instantly.
so if i load the large flash files on my web browser,
after 5 munites or something, the web browser is down.

IPod Shuffle: How to set the maximum volume limit

How do I get back to the volume default I set at the onset of using my shuffle?
I have speakers in my Ski Helmet and would now like to turn up the volume louder than I have currently set for my in ear earpods.
Any help is appreciated.

If you're talking about the Maximium Volume Limit:
Setting the Maximum Volume Limit
You can set a limit for the maximum volume on iPod shuffle. You can also set a
password in iTunes to prevent this setting from being changed by someone else.
If you’ve set a volume limit on iPod shuffle, the status light blinks orange three times if
you try to increase the volume beyond the limit.
To set the maximum volume limit for iPod shuffle:
1 Set iPod shuffle to the desired maximum volume.
2 Connect iPod shuffle to your computer.
3 In iTunes, select iPod shuffle in the Source pane.
4 Click the Settings tab.
5 Select “Limit maximum volume.”
6 Drag the slider to the desired maximum volume.
The initial slider setting shows the volume the iPod shuffle was set to when you
selected the “Limit maximum volume” checkbox.
7 To require a password to change this setting, click the lock and enter a password.
If you set a password, you must enter it before you can change or remove the
maximum volume limit.
Note: The volume level may vary if you use different earphones or headphones.
To remove the maximum volume limit:
1 Connect iPod shuffle to your computer.
2 In iTunes, select iPod shuffle in the Source pane.
3 Click the Settings tab.
4 Deselect “Limit maximum volume.”
Enter the password, if required.
Note: If you forget the password, you can restore iPod shuffle. See “Updating and
Restoring iPod shuffle Software” on page 26 for more information.

How to upgrade the CPU of Cisco ASA 5520?

Thank,

CPU usage goes off the meter everytime I start firefox and when I open add-ons tab to troubleshoot the CPU usage goes and then stays on normal.Why?

The CPU usage is 99% everytime I start firefox. When I open help tabs in the browser to troubleshoot the problem the cpu goes down to normal.How am I supposed to troubleshoot the issue if the last resort is as simple as uninstalling firefox?
Running: Firefox 5.0
OS. H.P. Windows XP/ sp3 , mem. 1536 MB , Pent.4.

Hi musicfan,<br />Sorry you are having problems with Firefox. Maybe you should have asked earlier and we could have fixed it.
Reading your comments I do not see that rolling back to an insecure Firefox 22 will actually help you much. You are probably best using IE, unless you have also damaged that.
*[[Export bookmarks to Internet Explorer]]
You should not use old versions they are insecure. Security fixes are publicised and exploitable.
* [[Install an older version of Firefox]]
* https://www.mozilla.org/security/known-vulnerabilities/firefox.html
Most others will not be having such problems. We are now able to say that with confidence because after developers missed a regression in Firefox 4 telemetry was introduced so that data was obtained. It may be an idea to turn on your telemetry, if you have not already done so, and decide to stick with Firefox.
*[[Send performance data to Mozilla to help improve Firefox]]
Trying safe mode takes seconds. Unfortunatly if you are not willing to do even rudimentary troubleshooting there is not anything we can do to help you.

Hi Guna,
To achieve this issue, we need to replace the value of #, we need to change the description while retrieving the data from tables. So we need to write some ABAP code in SE38. Go to RSA1 transaction and go to Info objects tab. Then go to context menu for cProject Key Figures as shown below. Click on the Object Overview to get the overview of all the info objects. Here you can see the field names which are used to know the table names.
In SE11, type the table name in Database Table field. Now press F4, then you will get the next screen to select one of the P/Q/S/T tables.
Now click on the button rounded in the below screen to view the data in the table.
Now click the execute button or press F8 to view the records.
Now go to Tcode: SE38. Create a source code and give some program name for that source code. To write code, you need access key. Contact your BASIS for this.
Now write the below code for that particular table in which you want to change the value # to description Blank. In the below source code, we are updating particular table, setting the field as Blank where it is null or no value. Here the field will automatically get updated to # if there is no value or null.
update /BIC/PXXXXX set /BIC/ZXXXX = 'Blank' where /BIC/ZXXXXX is null or /BIC/ZXXXX = ''.
if sy-subrc eq 0.
write 'successful'.
commit work.
else.
write 'unsuccessful'.
endif.
OR
If this # is because of the missing master data than,
right click that IO -> maintain master
you will see first row as a blank.
whatever value you maintain in this row that will come in the report for all Not assigned # values of the master data in the report.
maintain it according to your requirement, save and activate the master data
Hope this helps u...
Regards,
KK.
