1 Welcome to the HP Scalable Visualization Array V2.1 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 HP-developed software APIs and utilities (SVA Visualization System Software). Together, these hardware and software components bring the power of parallel computing to the task of image visualization for large data sets.
Because all the documentation is contained in a tree of Web-compatible files, you can also manually copy the tree to any web server root directory (Windows, UNIX, or Linux) and it can then be viewed via its URL by anyone with access to that web server. There is a zip file of the CD contents to facilitate this. 1. 2. 3. Mount the HP XC Documentation CD in the CD drive on an existing Windows machine or Linux machine (not part of the SVA). Locate the hpxc_v32.
For xw9300 systems, the minimum supported BIOS level is 2.05 or higher. Use of older versions of the BIOS results in network problems that prevent the cluster from working properly. • Solution Use the recommended BIOS versions. If you need to upgrade for some reason (for example, HP Field Service recommendation), you can find the latest BIOS versions on the HP web site. 2.
Substitute each display node used to drive the tiles in your display for n1. • Solution There is a Site Configuration File tag that fixes this problem. It is the SVA_FILL_DISPLAYS_ON_STARTUP tag in the SVA_CLUSTER section of the Site Configuration File. Set the value of this tag to “yes” in the Site Configuration File. This requires root privileges.
7. Job Launch: SLURM Epilog Script Excessive Clean Up • Impact Medium. • Summary The HP XC System Software Installation Guide uses a SLURM epilog script called slurm.conf. This epilog script runs as root when a SLURM job terminates on each node in the job. The epilog script terminates any rgsender processes on nodes used in a job (started when using HP Remote Graphics Software), removes any X lock files (for example, /tmp/.X0-lock, /tmp/.
9. 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 the all the nodes in the cluster, or the script fails. • Solution ssh to all the nodes in the cluster before using the script. When you access each node with ssh, you must do so twice by using each of the two names used by the nodes for each network.
. RGS: Incomplete RGS Installation Inhibits RGS GUI During sva_remote.sh Sessions • Impact Medium. • Summary If all RGS Sender installation steps are not completed as described in the HP RGS User's Guide, the RGS Sender GUI will not be present during SVA jobs started using the SVA job launch script, sva_remote.sh. This impairs access to the remote session, making collaboration among several remote clients difficult.
15. 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.
