1 Welcome to the HP Scalable Visualization Array V2.0 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.
1.1.3 Install Online Documentation You can wait until the cluster is up and running and view the online SVA Documentation Library already installed on all the nodes. The documentation files are in the /var/www/html/sva directory. The /var/www/html directory is where Apache stores HTML files on Red Hat systems. The documentation can be accessed from any cluster node at https://nh/sva. (nh is the default name for the head node as specified by HP XC.
— — — Parallel Compositing Library Reference Guide in the SVA Documentation Library for more information. Upgrade Chromium to V1.9. Upgrade HP RGS to V4.0 with enhanced firewall support. Updated documentation and manpages for new functionality. • Available in HP SVA V1.1 Patch Kit 3 — G-Sync cards for framelock work with two graphics cards per node. Previously, support existed for G-Sync cards to work only with one graphics card per node.
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.
After you begin a job using the sva_chromium_dmx.sh script, DMX indicates that it is starting by means of a message in the upper-left corner tile of a multi-tile display. The remaining tiles are black until the visualization application starts. You may have the problem if the application starts with an image that appears incorrectly offset in the upper-left tile when compared to the remaining tiles in the display. This may be because the tiles are using different resolutions.
7. Job Launch: Failure to Start Due to License • Impact Low. • Summary The job fails to start and displays a license error. • Solution Restart the license manager. This procedure is described in the SVA System Administration Guide. 8. Job Launch: SLURM Epilog Script Excessive Clean Up • Impact Medium. • Summary The SVA Installation Guide adds a SLURM epilog script to slurm.conf. This epilog script runs as root when a SLURM job terminates on each node in the job.
scancel: error: Kill job error on job id 431.17: Invalid job id specified • Solution This message is harmless and you can ignore it. The message is an artifact of how job cleanup is done. The cleanup script occasionally tries to clean parts of the job that didn't start. 10. Environment Variables: path/ld_library_path Conflicts • Impact Low. • Summary The SVA software adds items to PATH and LD_LIBRARY_PATH environment variables when the user logs in or starts a shell.
13. Compositing Library: Running your application produces the message: Error: Posting rdma recv host: [int] Max. WR number exceeds capabilities • Impact Medium • Summary Your application creates too many framelets. The Library has high but fixed limits on the number of outstanding messages it supports on the InfiniBand network. The application has exceeded this limit (roughly 1,000 outstanding messages per program). [int] is the hostIndex of the host whose message queue is exhausted.
