Control CPU usage of a program?

[Davy]

Hi all,

I am writing programs of algorithms using C++ and C. When I run the
programs,
I found the programs take 100 percent of the CPU usage and I cannot run
any other program.
How to control the CPU usage percentage?
For example, let the program take 30 percent of the CPU usage? Thanks!

BTW, the circumstance is Windows 2k and XP.

Best regards,
Davy

You can't really tell "Take 30 percent", but you can fiddle with thread
priority.

There is no way to control this in Standard C, it is off-topic here.

Good, ask in a group that focuses on those systems.

A reasonable OS will not let one looping program lock out others
unless the priorities have been set in a non-default manner to give
your program absolute priority over everything else (sometimes
called a "real time priority").

Since Windows 2000 is often used as a server, I find it difficult
to believe it's got a problem like this without some amount of
tweaking settings inappropriately (by either the admin or the
viruses). After all, it manages to cope with a busy webserver with
neither handling web pages nor running viruses locking each other
out.

I recommend reading the documentation that came with your OS.
Incidentally, I see no reason to limit your program from taking
100% of the CPU *IF THERE'S NOTHING ELSE TO RUN*. Otherwise, it
just wastes that CPU time.

You've asked this same question in multiple newsgroups now
(starting new individual threads in each by the way). You have
been given answers, please don't keep asking.

Paid writers!

I see there are paid writers in here...

Davy asks a legit question, and bs-answers like read the manual for your OS is one of the worse I've ever seen! Who are you working for? Microsoft?
