RHEA-2010:0056 - Product Enhancement Advisory

Topic

An updated libhugetlbfs package that adds a script to simplify huge page
setup is now available.

Description

The libhugetlbfs library interacts with the Linux hugetlbfs to make large
pages available to applications in a transparent manner.

This update adds the following enhancement.

• previously, huge pages worked well once configured but setting them up

was a complicated, multi-step, potentially error-prone process. This
updated package includes a script -- huge_page_setup_helper -- that asks
for three pieces of data and then sets up huge pages for use based on the
answers provided. The three data points required by the script are the
memory to allocate to huge pages and the group and users who should be
allowed access to the huge pages. (BZ#523346)

All huge pages users should install this updated package which includes
this enhancement.
