1 Getting Started This document provides information about the Patch Kit 3 release for HP SVA V1.1. 1.1 Overview of HP SVA The HP SVA development team is pleased to offer this updated version of its SVA product. This new visualization solution combines a cluster of industry standard PCs running HP XC and HP-developed software APIs and utilities (SVA Visualization System Software).
1.3.3 New Features in Patch Kit 1 The following new or changed features are available from the SVA V1.1 Patch Kit 1: • You can launch jobs from any node in the SVA cluster. Users are no longer limited to launching jobs from the head node. — As part of this change, the Site Configuration File was moved from /opt/sva/etc/sva.conf to /hptc_cluster/sva/etc/sva.conf.
3. HP XC: XC patch is incompatible with SVA • Impact High • Summary The XC patch XCV3.0-X86_64-1000334956 contains an updated X Server which is incompatible with SVA. • Solution We recommend that you do not install this HP XC patch. The X Server delivered as a part of HP SVA includes an extension which permits multi-tile displays to work effectively; that extension is absent from the X Server in this XC patch.
6. Display Configuration: X Display Server on a Workstation Head Node Defaults to 1024x768 @ 60 hz • Impact Medium. • Summary When installing on a head node with a graphics card, the default resolution is 1024x768@60 Hz. This was done to support users with a relatively low resolution display device (such as an RKM) connected to the head node. • Solution If your have a more capable display on the head node, you can change the /etc/X11/xorg.conf file to specify the resolution. The default xorg.
This is an effective way of ensuring that all pieces of your job go away when your job exits. However, if you have other processes on that node, even if not started by the job (for example, when debugging), they are also killed. • Solution You can disable the epilog by changing /hptc/slurm/etc/slurm.conf and restarting SLURM on all nodes using this command: pdsh -a service slurm restart Future SVA jobs may not be able to start if processes are left around by previous jobs and not cleaned up by the epilog.
11. DMX: 4K x 4k Total Display Device Restriction • Impact Low. • Summary When used alone, DMX only supports multitile display devices that total 4Kx4K pixels. • Solution Use the Chromium-DMX script interactively as documented in the User's Guide. 12. RGS: Incomplete RGS Installation Inhibits RGS GUI During sva_remote.sh Sessions • Impact Medium.
1.6 Software Availability in Native Languages HP SVA is available only in the English language. 1.
2 Installing Patch Kit This chapter describes how to install this patch kit. 2.1 Compatibility and Installation Requirements This section describes the compatibility information and installation requirements for this release. For specific installation instructions, refer to Section 2.2 and the HP SVA Installation Guide. 2.1.1 Required Patches Installation of this Patch does not require any previous patches. You can download the latest HP SVA Patch Kit from the following Web site: http://www2.itrc.hp.
2.2 Installation Procedure How you follow these installation steps depends on when you install the patch kit: • You are installing the patch kit as part of a full XC/SVA installation from scratch. 1. In this case, begin the installation procedure as documented in the V1.1 HP SVA Installation Guide. Complete through Step 10 in the Initial Installation on the Head Node section. 2.
• • 7. For workstation head nodes: The system switches back to the head node X Server automatically. You should then switch back to the alternate console, and log out. Switch back to the head node's X Server using Ctrl+Alt+F7 and log in as root again. For server head nodes: Log out of the alternate console. Switch back to the head node's X Server using Ctrl+Alt+F7. Run cluster_config and re-image the cluster. Refer to the HP SVA Installation Guide for details on these steps.
3 Using Patch Kit 2 Features The information in this chapter supplements the SVA System Administration Guide, the SVA User's Guide, and the SVA VSS Reference Guide. 3.1 Stereo Imaging on Display Devices In order to display stereo images on an SVA, you need to use SVA launch scripts to run your stereo-compliant application on a Display Surface that is properly configured for stereo. Configuring SVA for stereo is a system administration task and is detailed in Section 3.1.2.
The following SVA launch scripts support the --stereo option. • • • sva_chromium_dmx.sh sva_paraview.sh sva_job_template.sh 3.1.2 System Administrator Tasks: Configure SVA for Stereo The system administrator is responsible for installing the stereo support features of SVA and any ongoing configuration and maintenance to support stereo display devices. In order to display stereo images on an SVA, you need the following: • • An application that is capable of displaying stereo images.

Table 3-1 Default Supported Resolutions/Refresh Rates in the Site Configuration File Tag Mode Resolutions Refresh Rates SVA_SUPPORTED_RESOLUTIONS Mono 1280x1024, 1920x1200, 1600x1200, 1400x1050, 1280x960, 1152x900, 1024x768, 1024x768_60, 800x600, 640x480 VESA Standard Refresh Rates. These are appropriate for most desktop display devices.
to display images properly (for example, a blank display or an unsupported resolution error), you should review the Monitor Properties files located in /hptc_cluster/sva/etc/X11/templates/monitors to verify that they contain information appropriate for your displays. You should also review Table 3-1 for default supported resolutions. Changing the X Config Files can be complicated. You need to consult your display device documentation for specific display specifications.
Monitor Properties File because your display refresh rate is not 110 Hz (the default). You also need to change the VertRefresh entry, for example, to a range of 55–130 Hz. IMPORTANT: Consult your display device documentation for your display's specific properties. The more exotic your display (for example, stereo, projector, cave systems), the more likely you need to use the display vendor's documentation for the modeline information, refresh rate, and resolution.
Example 3-1 Sample DefaultStereo.monitor File Section "Monitor" Identifier "SVAStereoMonitor" # These settings represent a generic, stereo-capable monitor. # You should replace these values with values that are appropriate for # your stereo-capable monitor.

Once a Display Surface is defined as stereo-capable, users can launch a visualization job on that Display Surface as either a mono (the default) or a stereo display. See Section 3.1.1 for more information on how to do this. 3.1.2.4.1 Create a Display Surface When a system administrator creates a Display Surface using the Display Surface Configuration tool, they define the stereo mode. This is the most likely scenario if you want to take advantage of stereo support for your system.

You can access this file url from any node in an SVA cluster. 3.2 Set Default Tile Resolution for a Display Surface The information in this section supplements the information in the HP SVA System Administration Guide on the contents of the Site Configuration File that impact Display Surfaces.
Enter request:2 Please enter the display surface name to create. Mono_1 Is this display used for stereo graphics? y/[n] n Each tile in the display surface will use the same resolution. The supported resolutions for this cluster are shown below: 1) 2) 3) 4) 5) 6) 7) 8) 9) 10) 640x480 800x600 1024x768 1024x768 @ 60 Hz 1152x900 1280x960 1280x1024 1400x1050 1600x1200 1920x1200 Select the tile resolution from the list above [7]: 9 The prompt sequence is similar for Options 2 and 6. 3.
Interactive and non-interactive jobs can enable hardware framelock on any Display Surface by passing the new --framelock parameter to the appropriate SVA job launch script. The following scripts support the option • • • sva_chromium_dmx.sh sva_paraview.sh sva_job_template.sh 3.3.
