May i ask why you want to do this?

This is incredible. We already had a number of questions where people see that their applications use, by their opinion, too much of CPU and want to reduce this amount. I don't know why. And now you are asking, like some other inquirers, honw to use all CPU; probably it means 100%.

I have no idea why anyone would need it. Anyway, nearly always, if some manages to use about 100% CPU in one application, it typically means that this application does something extremely stupid. However, if this is not UI application and when all other applications are inactive (say, all threads of other applications are in wait state, which is a normal thing; it happens with all UI application when then don't do any background processing and nobody sends any input events with keyboard or mouse) then, yes, the percentage CPU usage of this only application can be very high.

No, CPU usage of your single application is not defined by its application only. They say, the usage depends on the operating environment. There are other applications. But it's very important that developers develop applications which don't do something stupid, wasting CPU time. And such stupid things are nearly unavoidable if someone develop applications with the goal of having certain percent of CPU usage, no matter low or high.

The OS does its best to balance scheduling using available CPUs or CPU cores and loaded processes, and it's important to used the available resources well, not wasting it and not blocking other processes, and not letting other processes to block yours. And, in fact, this is pretty easy to achieve. It's just enough to avoid some stupid things.

Now, just one practical advise: you can change the priorities of the threads and processes. Don't do it. The cases when it should be done are extremely rare, in all other cases you can only make things worse. First of all, don't do it before you get to good understanding of what applications should do.

I can only assume that TS checked Task Manager and discovered his application process uses just one core, 50/25/12.5% of total CPU time. Isn't that ineffective for highly loaded applications?! :)
I agree with you: before you start working with thread priority and processor affinity, you need a good understanding of what you want to achieve and what are the consequences.

Dear devoter, what OP want is the best thread mechanism which can utilize the cores in equal manner. That is what the overall meaning of this question. So I don't think that I have posted something wrong.
