Components of the HP Cluster Platform

Because the SVA is an extension of the HP Cluster Platform, you can begin by understanding its base

components without any visualization nodes. The following are the key architectural components of an HP

Cluster Platform system without visualization nodes:

Compute Nodes

and

Administrative/Service Nodes

The compute cluster consists of compute nodes and administrative or

service nodes. Parallel applications are allocated exclusive use of the

compute nodes on which they run. The other nodes provide

administration, software installation, remote login, file I/O, external

network access, and so on. These nodes are shared by multiple jobs,

and are not allocated to individual jobs.

System Interconnect (SI)

A high-bandwidth, low-latency network which connects all nodes. This

supports communication among the compute nodes (for example, MPI

and sockets) and file I/O between compute nodes and a shared file

system.

Administrative Network

An Administrative Network connects all nodes in the cluster. In an HP

XC compute cluster, this consists of two branches, the Administrative

Network and the Console Network. This private local Ethernet network

runs TCP/IP. The Administrative Network is Gigabit Ethernet (GigE);

the Console Network is 10/100 BaseT. (Because visualization nodes

do not support console functions, visualization nodes are not

connected to a console branch.)

Linux

The nodes of the cluster run a derivative of 64-bit Red Hat® Enterprise

Linux Advanced Server.

Note

All nodes must attach to two networks using different ports, one for the SI and one for the Administrative

Network.

Main Visualization Cluster Tasks

The SVA has a number of tasks that are unique to a visualization cluster. It accomplishes these tasks using

a set of unique node types that differ in their hardware configurations, and so are capable of different

functional tasks. The main tasks are as follows:

Render images. A node must have a graphics card to render images. A visualization

job uses multiple nodes to render image data in parallel. A render

node typically communicates over the SI with other render and display

nodes to composite and display images.

Display images. The final output of a visualization application is a complete displayed

image that is the result of the parallel rendering that takes place during

an application job. To make this possible, a display node must contain

a graphics card connected to a display device. The display can show

images integrated with the application user interface, or full screen

images. The output can be a complete display or one tile of an

aggregate display.

Remote images. The SVA also supports the transmission of a complete image to a

system external to the cluster over an external network for remote

viewing; for example, to an office workstation outside the lab. A node

with a port connected to the external network is recommended.

Alternatively, you can connect to the external network by routing

through another cluster node with such a port.

Integrate an application user

interface.

An application user interface (UI) usually runs on a cluster node. The

UI typically controls the parts of the distributed application running

on other nodes. A node that provides users with acess to the UI can

have an attached keyboard, mouse, and monitor for user interaction.

Alternatively, the node can export the application UI to an external

node using the X protocol or using the HP Remote Graphics Software
