Advising Prolog processor to utilize huge-pages

Are there any Prolog implementations which support utilizing huge-pages (2MB/4MB per memory page) instead of the vanilla 4Kb memory pages.

Ideally, I would like to declare to the interpreter/compiler/run-time that it's okay to use X huge-pages for various heaps/stacks/scratchpad-memory for some particular application.

Of course, not all applications could benefit from this, but I am sure that there are more than a few that would. Megabytes are the new kilobytes, after all:)

Solution

  • Since some Prologs runs on the Java JVM, and since some Java JVMs have a flag for that, I guess the answer is yes. See also:

    There are a couple of Prologs running on the Java JVM:
