Additional notes about huge pages:

Huge pages is an advanced OS feature that has pros and cons. Users should be familiar with the
issues before enabling huge pages at the OS level. Reserving too many huge pages can destabilize
the system.

cpuminer-opt will automatically use 2 MB huge pages on Linux for Verthash and Scryptn2 if they are
available. The miner does not reserve huge pages, it will only use what has been reserved by the OS.
There is no need to run the miner as root to use huge pages.

Confirmation of huge page use can be done in 2 ways: cpuminer logging which may
require --debug, or by using the proc file system to monitor huge page usage in the system.


Huge pages are not supported on Windows at this time.
