Greetings...please let me know if I am posting to the wrong forum.

I have an RHEL 6.1 server, with 32GB Ram, 24 CPUs

I am running an inhouse developed application, and while the application works...its running very slow.

Looking at System Monitor, I can see that minimal RAM is being used...but that all the CPUs arent being used effeciently. By that I will see that one , two or three CPUs might be at 50% -99% utilization while the rest are at 0%. I will see that at certain points the other CPUs will start processing some of the work, but will never see more than a couple of the CPUs kick in to start working. Just wondering if there was a way to get more of the CPUs to kick in and help out with the processing...ie to see all the CPUs processing something

Thanks for any suggestions.

You might actually have some general problem in your system, that you would need to handle.

But if you want to try to coax the application to use a particular CPU, you can learn how, by executing from a command prompt, a command such as:


or if you don't have the apropos command, you should be able to do this:

Thanks...but I am not trying to get the application to just use one of the CPUs..I am trying to get the application to start using all the CPUs that are available. Thru the system monitor...out of the 24 available CPUs...I see 2-3 of the CPUs, randomly, doing any of the work. I would like to see if I can get all of the CPUs to start handling some of the workload.

Thanks

That requires that the App(s) are built to be multi-processins and/or multi-threading.
