CPU consumption

Hello experts,

I am writing an application in Solaris, which is supposed to work on PrimePower 650 and SunFire 440 machines. The application listens to the events raised by the Hardware and OS in /dev/log. The application listens to the messages logged into /dev/log and do some processing on them. Now, when there is a load condition occuring at /dev/log(i.e. number of messages per second ocurring at /dev/log is high), CPU consumption by my application shoots up to 50%, while my application is expected to consume not more than 1% CPU.
Now, I want to bring down the CPU consumption to 1%. Since the CPU consumtion can vary according to various CPU configurations, i have to ensure that the CPU consumption remains below 1% for low end CPUs.

Thanks in advance.

Currently to solve this problem, i am using the following technique:
1.Process is only reading 5 messages per second from /dev/log and process them. The process sleeps for rest of the time per second.
2. Every 100 messages, the process sleeps for 5 seconds.

This solution brings down the CPU consumption. On some CPU configurations, it is less than 1% CPU consumption. But on others still varies from 3-13%.

Please tell me if the processing delay technique used has some fundamental faults, or what is the correct technique of introducing processing delay for controlling CPU consumption.

Please also tell your suggestions for controlling CPU consumption. I would also appreciate , if you can redirect me to some links where i can find CPU consumption control techniques and fundamentals.

Thanks and regards.

You do realize that this site supports development on Windows machines, right?

I'm not saying that this question won't get answered, but this is not the best site for *nix-based development questions.

Hi, I have a problem about my internet explorer. Last week my IE run fine but this week it has a problem. The problem is, when i open any link that require to start new IE browser, the previous IE windows is disappear. But if the link do not require to run new IE browse than it work fine. From here i don't understand why this problem occure. Can anyone give me any idea relate to this issue?

Note: I suspect this computer affect with spyware. Because i used this computer to download many trail software a whole night. But when i scan for spyware using windows anti-spyware, there is no spyware found on my machine.

I'm assuming this is a recent problem, if it is have you tried running a System Restore[^] and resuming from a previous state?

If this doesn't work I'd check that MS AntiSpyware is upto date and it might be a good idea to try sweeping the computer with another spyware scanner like Ad-Aware[^] or something to be doublely sure.

I never create a restore point, so i can't use system restore in my computer.

I also have windows anti-spyware in my computer. And its automatically scan my computer at 2am during the time that i download a trail software. But its result never found anything. Maybe I need to return back to check it definition again because i think it was update automatically from the web.

Thats cool, Windows automatically makes a restore point for you on very a regular basis (every other day or something), so it's worth trying it anyways.

As for Ms AntiSpyware, I'd still try running a sweep with another scanner to be sure, from experience different scanners find different things.

I forget to tell you that i used to turn off system restore on all drive since the time that i install my windows. Because i heard that system restore will back up the virus into the computer if the virus infect my system.

Beside Ms windows anti-spyware and Ad-aware that you provide to me in the previous link, did you find any other tool that could clean the system effectively?

Well, you got bad advice. So what if the virus gets backed up? That's what anti-virus software is for! The point of a restore point is to create a last-known-good backup of the system. On XP, most application installers will force a restore point to be created before the installation takes place. This makes it very easy to go back to the old system if the new application screws something up. Or is your case, something unknown screws soemthing up.

There's a bunch. All you have to do is Google for "Anti Spyware".

Hi, trying to set up clustering with vmware. Following instructions on the following articles:

REF 1 Set up VMware to install Windows clusters. http://techrepublic.com.com/5100-1035_11-1058354.html
REF 2 Using the VMware SCSI Disk Driver for Windows Guest Operating Systems. http://www.vmware.com/support/refer...in_scsidrv.html

I download from REF 2 and I didn't see any zip file (which contains the pln and dat files) mentioned in REF 1. All I found was a file named "vmscsi-1.2.0.2.flp". Any clue? Thanks.

Boot device

Hi, my computer have a network card that do not support to boot from a network. Now I'm need to study the lesson on remote installation which require to boot from the network. Does anyone know any device (exp: usb) that just connect to my computer and it will boot to the specific machine in order to install OS from the remote destination?

Dave Kreskowiak6-Feb-06 4:12

6-Feb-06 4:12

You'll need a network card that support PXE Boot, and you'll need a service running on whatever server you're using that supports PXE. For Windows servers, this is the Remote Installation Services[^] or Automated Deployment Services[^].
That's really the only way you're going to learn how it works in the real world.

Yes, I know about that. Currently, i have a network card that do not have PXE boot rom. What i want is just buy a usb pxe boot device that just plug to the usb port and configure in CMOS. Then my computer could boot up to install OS from the specific server.

Do you have any idea?

Dave Kreskowiak6-Feb-06 5:15

6-Feb-06 5:15

There is no USB PXE Boot device. You CAN however boot from a USB ThumnbDrive (if your system supports it!). In that case, all you need to do is configure a PXE Boot Disk using what Service you have installed on your Server, and put that on the ThumbDrive.

Hi everybody,

From last few weeks, I am struggling to make my color monitor look like black and white monitor.

Can anyone suggest me any means, by which I can change my windows theme to be completely black and white.

Or by programming, how can I change my graphics driver to render my windows in black and white.

I am getting very desperate to get this done, please help me in any way..struggling for this has already wasted my lot of time.

thank you community in advance if you can come up with some solution to me.

cheers.
