How to set the page size with Intel processor

Hey hello everyone,I'm not sure it's the right place to post this question. But I cannot find somewhere better.My processor is Intel Xeon 5620, Since I get from the Intel's developer manual that it supports page sizes from 4K-1G. In my case, I wanted to use investigate the impact of the page sizes to my program's performance. But I cannot find some way to do it. Can anyone help me by telling me how to set the page sizes on this processor?Do I need do BIOS setup, or some OS configuration, or can just using some inline assembly in the code to set the page size?Thank you!

For more complete information about compiler optimizations, see our Optimization Notice.

AFAIK the OS is responsible for all the virtual memory related stuff so I guess your OS needs to support changing the page size. But I never heard of something like this.
