How to set the clock of a CPU core to max?

For my project I need a CPU for some special processing.
I managed to isolate a CPU core from linux and run my own process/thread on it.
But the CPU clock is changing depending the load. I do not want that for this core.
How can I configure the system such that it just sets the CPU clock to the maximum clock for that core?
