Rocks v5.0 is released for i386 and x86_64 CPU architectures.


ISO images for i386 and x86_64 architectures can be found here.

New Features

  1. Xen Support
  2. You can use the Xen Roll to create 'VM Containers': physical machines that are used to hold Xen-based virtual machines. The Rocks Command Line was expanded to help build and maintain VMs (e.g., "rocks create host vm compute-0-0-0" is used to install a VM).

  3. Fully-Programmable Partitioning
  4. The partitioning of client nodes (e.g., compute nodes and tile nodes) has been retooled. You can supply Red Hat partitioning directives to any node by writing a program in the "pre" section which populates the file "/tmp/user_partitioning_info". The program can be as simple as small bash script that echos Red Hat partitioning directives or as complex as a python program that outputs partitioning info based on: the node's name, the node's membership, the number of disks in the node or the type of disks in the node. See the Base Roll documentation for details.
