1 Welcome to the HP Scalable Visualization Array V1.1 Release The HP SVA development team is pleased to offer this initial 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). Together, these hardware and software components bring the power of parallel computing to the task of image visualization for large data sets.
You can also view the full set of online documentation directly from the SVA CD using a Windows or Linux system. The main navigation page for the Documentation Library is located on the CD at the following location: sva/index.htm Because all the documentation is contained in a tree of Web-compatible files, you can also 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.
3. Displays: Display Surface Names Cannot Have Spaces • Impact Low. • Summary The Display Surface Configuration Tool can only create Display Surfaces without spaces in the name. • Solution Use names without spaces, for example, MY_DISPLAY rather than MY DISPLAY. 4. 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.
6. 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. 7. 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.
9. Job Termination: Spurious scanel Warnings • Impact Low. • Summary Occasionally, jobs end with an warning similar to the following: 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. DMX: DMX Console Breaks SHIFT/control/caps LOCK KEYS • Impact Low.
. 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. If these values are over written, then the SVA tools will not be able to start. • Solution Instead of replacing a PATH/LD_LIBRARY_PATH, you should append any new values to existing values in the environment variables. 13. DMX: 4K x 4k Total Display Device Restriction • Impact Low.
