The parallel compression tool ``pigz`` can be enabled by installing ``pigz`` package on the management server or diskless rootimg. Depending on the method of generating the initrd and compressed rootimg, the steps differ in different Linux distributions.

The package ``pigz`` is shipped in Extra Packages for Enterprise Linux (or EPEL) instead of RedHat iso, this involves some complexity.
Extra Packages for Enterprise Linux (or EPEL) is a Fedora Special Interest Group that creates, maintains, and manages a high quality set of additional packages for Enterprise Linux, including, but not limited to, Red Hat Enterprise Linux (RHEL), CentOS and Scientific Linux (SL), Oracle Linux (OL).
EPEL has an ``epel-release`` package that includes gpg keys for package signing and repository information. Installing this package for your Enterprise Linux version should allow you to use normal tools such as ``yum`` to install packages and their dependencies.

1) Enabling the ``pigz`` in ``genimage`` (only supported in RHELS6 or above)
``pigz`` should be installed in the diskless rootimg. Download ``pigz`` package from https://dl.fedoraproject.org/pub/epel/ , then customize the diskless osimage to install ``pigz`` as the additional packages, see :doc:`Install Additional Other Packages</guides/admin-guides/manage_clusters/ppc64le/diskless/customize_image/additional_pkg>` for more details.
2) Enabling the ``pigz`` in ``packimage``
``pigz`` should be installed on the management server. Download ``pigz`` package from https://dl.fedoraproject.org/pub/epel/ , then install the ``pigz`` with ``yum`` or ``rpm``.
* **[UBUNTU]**
Make sure the ``pigz`` is installed on the management node with the following command::
dpkg -l|grep pigz
If not, ``pigz`` can be installed with the following command::
apt-get install pigz

1) Enabling the ``pigz`` in ``genimage`` (only supported in SLES12 or above)
``pigz`` should be installed in the diskless rootimg, since``pigz`` is shipped in the SLES iso, this can be done by adding ``pigz`` into the ``pkglist`` of diskless osimage.
2) Enabling the ``pigz`` in ``packimage``
Make sure the ``pigz`` is installed on the management node with the following command::
rpm -qa|grep pigz
If not, ``pigz`` can be installed with the following command::
zypper install pigz
