HP SVA V1.1 Patch Kit 3 Readme/Release Notes

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.conf already
has a specification for a more capable display device, and turning it on is relatively
straight forward.
To make the change, edit the /etc/X11/xorg.conf config file on the head to
change the specific monitor from RKM to MyMonitor.
Original configuration in file:
#Monitor "MyMonitor"
Monitor "RKM"
New Configuration:
Monitor "MyMonitor"
#Monitor "RKM"
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.
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/.X1-lock), and invokes the optional XC epilog script, which
kills any processes owned by the user running the job (except for root and any other
UID less than 100).
