Chapter 2. Installation Prerequisites

Installing Red Hat HPC Solution (Red Hat HPC) requires one system to be designated as an installer node. This installer node is responsible for installing the rest of the nodes in the cluster.

Prior to installing Red Hat HPC, confirm that the designated machine has Red Hat Enterprise Linux 5.3 installed and meets the following requirements:

Root partition with at least 40 GBytes free.
Disable SELinux.
One or more network interfaces use a statically defined IP addresses. Connect these to the networks where the machines are provisioned.
Red Hat Enterprise Linux Version 5.3 installation media
A valid subscription to Red Hat Network is required including an entitlement to Red Hat HPC Channel
The firewall (iptables) must be configured to permit the services needed for installation on all networks used to provision nodes (HTTP, HTTPS, TFTP, DNS, NTP, BOOTPS, etc). A script is provided to appropriately configure the firewall.
Red Hat HPC creates a private DNS zone for all machines under its control. The name of this zone must NOT be the same as any other DNS zone within the organization where the cluster is installed.
