HP SVA V2.1 Visualization System Software Reference Guide

Table 2-1 Environment Variables for Running Applications (continued)
DescriptionVariable
This variable is initially set to 0. However, if
SVA_RENDER_COUNT is specified in the User
Configuration File, it is set by svaGetJobDefaults. It
can also be set by the command line argument -r in some
scripts; for example, the sva_job_template.sh.
Before the job is allocated, the SVA_Render_Count value
is used to request rendering resources for a job. After the
job is allocated, SVA_RENDER_COUNT is used to control
job steps to rendering resources.
This value is also stored in the Job Settings File, SVA_JOB
section, SVA_RENDER_COUNT tag. Do not modify this
value after the job is allocated.
SVA_Render_Count
svaAllocateJob sets this variable to the condensed
host names of the render hosts allocated to the job. This
value is also stored in the Job Settings File, SVA_JOB
section, SVA_RENDER_HOSTS tag. Do not modify this
value.
SVA_Render_Hosts
svainit sets this variable value to 0. Set this value to 1
to enable shell debugging. See the Bash shell set -x
command manpage for more information.
SVA_Debug_Flag
This variable is initially set to 0. After the job is allocated,
it controls job steps to display resources. This value is also
stored in the Job Settings File, SVA_JOB section,
SVA_DISPLAY_COUNT tag. Do not modify this value.
SVA_Display_Count
svaAllocateJob sets this variable to the condensed
host names of the display hosts allocated to the job. This
value is also stored in the Job Settings File, SVA_JOB
section, SVA_DISPLAY_HOSTS tag. Do not modify this
value.
SVA_Display_Hosts
This variable is initially set to null. However, if
SVA_DISPLAY_SURFACE is specified in the User
Configuration File, it is set by svaGetJobDefaults. It
can also be set by the command line argument -d in some
script; for example, sva_job_template.sh. This value
is used to select display resources in svaAllocateJob.
SVA_Display_Surface
This variable is initially set to null. However, if
SVA_EXECUTION_HOST is specified in the Site or User
Configuration File, it is set by svaGetJobDefaults.
Normally this value is set from the Display Surface
properties; that is, one of the display hosts that make up
the allocated Display Surface. If this variable is specified
in the User Configuration File, the value must be one of
the display hosts allocated to the job.
This value is used to control where DMX and the user's
application master program start. Do not modify this
value after the job is allocated.
SVA_Execution_Host
This variable indicates whether the cluster has a KVM. 0
indicates there is no KVM (default); 1 indicates there is a
KVM.
SVA_KVM
This variable indicates the number of display devices
attached to the display node. 1 indicates one display
device; 2 indicates two display devices.
