1 Welcome to the HP Scalable Visualization Array Version 2.1.1 Release The HP SVA development team is pleased to offer this version of its SVA product. This visualization solution combines a cluster of industry standard workstations and servers running HP XC and the software APIs and utilities (that is, the SVA Visualization System Software) developed by HP. Together, these hardware and software components bring the power of parallel computing to the task of image visualization for large data sets.
• DVI-compatible modelines for resolutions 1600x1200@60Hz and 1920x1200@60Hz Additional DVI-compatible modelines, for resolutions 1600x1200@60 and 1920x1200@60, added to the current set. • Allowing users to add Options to the Device Section of SVA-generated X Configuration Files This change allows you to add Option lines to the Device section of the xconfig.py file without having to edit it. A similar approach currently exists for adding the modelines to the Monitor section within the xconfig.py file.
2 Installing the Patch Kit This chapter describes how to install this patch kit. The topics include: • • • “Compatibility and Installation Requirements” (page 9) “Installation Procedure” (page 10) “Running the SVA OVP utility” (page 10) 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 XC System Software Installation Guide. 2.1.
2.2 Installation Procedure IMPORTANT: Do not install this patch kit as part of a brand new HP XC/HP SVA installation. You must install the patch kit over an existing HP XC/HP SVA installation. Follow these steps to install the patch kit: 1. 2. Log in as root on the head node of the HP SVA cluster. Determine if you have added any custom modelines to either or both of these files: • /hptc_cluster/sva/etc/X11/templates/monitors/DefaultStereo.
If you use the X Server on the head node for the DMX Console window, run the following command before running the sva_ovp utility: # xhost + To start the sva_ovp utility, enter the following command on the head node: # sva_ovp For detailed information on the options for this utility, see the SVA System Administration Guide. 2.
3 Release Notes This chapter lists the release notes that apply to this release. Each item is presented with an estimate of its impact, a summary of the note, and a solution. 1. Allow Administrators to Add Options to the Device Section in SVA-generated X Configuration Files • Impact Medium. • Summary This functionality allows the system administrator to implement device options with the configuration files generated by SVA.
a. b. c. Log out from the server. Drop to run level 3. Run the following command to uninstall the rpm for the NVIDIA driver: # rpm -e nvidia Continue with the regular SVA installation/upgrade procedure. 3. BIOS: Minimal Supported Versions • Impact High • Summary The factory versions of the installed HP workstations xw8200 and xw9300 BIOS or higher are the only supported versions. For xw9300 workstations, the minimum supported BIOS level is 2.05 or higher.
6. Displays: sva_chromium_dmx.sh Script Fails to Start All Tiles in a Multi-Tile Display with Correct Resolutions in Non-Interactive Mode • Impact Medium. • Summary Depending on the display hardware on your cluster, use of the sva_chromium_dmx.sh script in non-interactive mode may not start all the tiles in a multi-tile display with the correct resolutions. Normally, all tiles should share the same resolution as determined by the Display Surface default resolution.
New Configuration: Monitor #Monitor 8. "MyMonitor" "RKM" Display Configuration: Root Access Option Needed for Display Surface Configuration Tool • Impact Low. • Summary The options that need root access in the Display Surface Configuration Tool (svadisplaysurface) do not work if you set root access using the su command and then run svadisplaysurface. • Solution Use su - instead of su. Then run svadisplaysurface. 9. Job Launch: SLURM Epilog Script Excessive Clean Up • Impact Medium.
10. Job Launch: Scripts Fail in Directories with Spaces in Names • Impact Low. • Summary Scripts do not work if executed within directories containing spaces in their names. • Solution Change to a directory which does not have a space in its name. 11. Job Launch: EnSight Script Requires Previous ssh Login • Impact Low. • Summary Before using the sva_ensight82.sh script for the first time, you must ssh to all the nodes in the cluster, or the script fails.
14. 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. 15. RGS: Incomplete RGS Installation Inhibits RGS GUI During sva_remote.sh Sessions • Impact Medium.
17. Compositing Library: Unwanted changes to the color buffer when using PC_PF_Z24I (24 bit depth component) • Impact Low • Summary When using PC_PF_Z24I for depth compositing, the Library copies the depth pixels to the color buffer. The color buffer is then read back to get the depth pixels. The color buffer is not restored with the earlier content. • Solution If you want to keep the color buffer unchanged while doing depth compositing, then consider using a different pixel format.
