DefinitionTags within Section
SVA_JOB
Declares default settings for all jobs.
Provides a means to supply options to the SVA job allocator. These
options affect its choice of nodes.
More than one option can be used by separating the options with
a space. Options include:
SVA_ALLOCATOR_OPTIONS
--matchgpucount: Forces the job resource allocator to select
only render nodes containing the same number of GPUs required
to support each display block in the Display Surface. A three- or
four-tile display block then requires render nodes with two GPUs.
If there are not enough of those nodes, the job does not start.
Without this option, the job resource allocator may select render
nodes with four GPUs.
--onlyrender: During an RGS job, do not select display nodes
for use unless asked for one specifically.
The name of a Display Surface to use for a job when no Display
Surface is specified in the job script options.
SVA_DISPLAY_SURFACE
The name of the SLURM partition from which to request resources.
Refer to the HP XC documentation for more information on SLURM.
SVA_PARTITION
1
The name of the node on which the master component of an
application runs.
This tag value is set in the Job Settings File during job allocation.
When set in the User Configuration File, it specifies where the
DMX server runs and where the application main program runs.
The execution host value must be the name of one of the hosts
allocated to a job. If the value is not set in the User Configuration
File, it defaults to the execution host specified for the job Display
Surface.
SVA_EXECUTION_HOST
The number of render nodes requested for a job.SVA_RENDER_COUNT
2
The number of compute nodes requested for a job.SVA_COMPUTE_COUNT
2
Indicates whether or not DMX is used for a job.SVA_USE_DMX
1
The name of the node from which keyboard and mouse input
comes. If not specified, this defaults to the first display node.
SVA_DMX_INPUT
The name of the node on which XDMX runs. XDMX requires little
overhead. It can run on any node; however, it is better to use job
resources. If not specified, the tag value defaults to the first display
node.
SVA_DMX_STARTUP
Indicates whether or not HP Remote Graphics Software is used
for a job.
SVA_USE_REMOTE3D
1
Provides a means to supply options to the X Servers. The Site
Configuration value is set by running the svaconfigure utility
or by a root user with an svaputdata call.
For example, SVA_X_OPTIONS="-ac".
SVA_X_OPTIONS
1
Defines the geometry of the Display Surface tile. Typically this
defaults to the natural size for the X Display. For example,
1280x1024.
This value is passed to the X Server when it is started for a job.
SVA_TILE_GEOMETRY
1
Turns the X cursor on or off on display nodes.
A value of 0 sets the cursor to appear on nodes. A value of 1 sets
the cursor not to appear on nodes.
SVA_UNCLUTTER
1
1 This tag is also defined in the Site Configuration File.
2 This tag is also defined in the Job Settings File.
