HP Insight Cluster Management Utility v7.2 User Guide

8.7 Support for Intel Xeon Phi cards
HP Insight CMU can be configured to support cloning the OS image when Intel Xeon Phi cards
are present in the compute nodes and the Intel Xeon Phi software is installed. HP Insight CMU also
supports booting a oneSIS diskless OS image to all compute nodes that have Intel Xeon Phi cards
installed and the Intel Xeon Phi software installed. However, in both cases HP Insight CMU is only
providing the OS file system.
IMPORTANT: The user is responsible for flashing the Intel Xeon Phi cards with the firmware after
the OS file system is deployed, which is required before booting the Intel Xeon Phi cards.
By default, the software for the Intel Xeon Phi cards is pre-configured with local network access to
the Xeon Phi Linux OS environment from the host server only. This configuration can be cloned by
HP Insight CMU without any tuning to the HP Insight CMU cloning process. This configuration can
also be booted into a oneSIS diskless environment, and the only required customization to the
image is configuring the portions of the single image file system where the Intel Xeon Phi software
expects to have write access. These customizations can be extracted from the example below.
The Intel Xeon Phi cards can also be configured with independent IP addresses and bridged with
the Ethernet network device on the local host enabling Intel Xeon Phi card access directly from any
other compute node or Intel Xeon Phi card on the cluster network. In this configuration, the HP
Insight CMU post-cloning process must be scripted to configure the network bridging and the
independent IP addresses for each Intel Xeon Phi card in the cluster. This configuration can also
be booted into a oneSIS diskless environment, which involves the same network scripting
requirements combined with configuring the writeable portions of the file system. “Intel Xeon Phi
card IP address and host name assignment algorithm” (page 151)discusses the general host name
and IP address algorithm recommended for the Intel Xeon Phi cards to support both of these HP
Insight CMU OS provisioning methods. “Cloning an image with Intel Xeon Phi cards configured
with independent IP addresses” (page 152) provides details on cloning this configuration. “HP
Insight CMU oneSIS diskless file system support for independent addressing of Intel Xeon Phi cards”
(page 154) provides details on booting a diskless image with this configuration.
To configure one or more Intel Xeon Phi cards with a host name and an independent IP address
and to bridge with the network device on the local host, the following settings must be implemented.
The following examples assume a RHEL OS on the host compute node:
• /etc/hosts must contain the host names and IP address(es) of the Xeon Phi cards.
