Is it possible to prioritise CPU power in java?

Hi guys,

I'm writing a program that will automatically run when a screen saver is loaded. Problem is, I'm trying to make it as CPU intensive as I can, because its a program that just crams out calculations.

I'm wondering if any knows anywhere I can find information about how to draw out as much CPU power as possible. Or even if there's a way of temporarily pausing all unnecessary programs while mine runs or something along those lines? I don't want to have to do it manually everytime, I need my program to implement it itself.

Let me know if you can help! Thanks!!

One thread is enough! [SOLVED] Is it possible to prioritise CPU power in java?

Don't cross post your questions on different forums... it just angers people and you don't get the support you were looking for. Select a forum and stick with it. If it's the wrong forum, people will let you know.

There's worse things in the world to get angry about guys..

My apologies for putting it in both the beginners and advanced section, I'm new here and just thought it'd reach a larger audience as I didn't think there'd be many people that could help with me with this one. Do either of you actually have any suggestions about the question I posted though?

If not, take a chill pill and ignore it. But to keep yas happy, I've removed the one from the advanced section, so that no more tears will be shed..

peace!

Sounds like an OS specific problem. Java is supposed to be independent of OS, so you'll need some JNI code to get at the OS stuff.

I agree with Norm... this is OS & HW specific. The only thing that I could find was the following:

Don't know if it will help.

PS: I'm not angry... just letting you know what is expected when using the forum. No need for a chill pill

The only thing this does is cause frustration, because people will spend a lot of time trying to help you, only to find out someone beat them to it somewhere else. Therefor wasting their time for nothing.

That - and at the same time being ignorant - will make it impossible for you to get assistance whatsoever in the future.
