Rocks Toolkit 5.2 released

Rocks v5.2 is released for Linux on the i386 and x86_64 CPU architectures and Solaris for the x86_64 architecture.
Rocks is an open-source Linux cluster distribution that enables end users to easily build computational clusters, grid endpoints and visualization tiled-display walls.

New features

Solaris support for client nodesThe above post section will only be executed if the attribute “foo” is set to “123″ for the installing host.

With the new JumpStart Roll, one can now install and configure a Linux-based Rocks frontend to “JumpStart” Solaris-based back-end machines.

Attributes

Can assign “attributes” to nodes at four levels: global, appliance type, OS (e.g., Linux or SunOS), and host. An attribute can be accessed in an XML node as an entity. For example, if you assign the attribute “foo” with the value “123″ to compute-0-0 (i.e., with the command, “rocks set host attr foo 123″), then in an XML node file, you can access the value of the attribute foo with “&foo;”.

Attributes also enable “conditionals”. Using the example above, a “post” section can be optionally executed based on the value of an attribute. For example, if a post section is defined as:

<post cond=”foo=’123′”>
