Table 2-1 Environment Variables for Running Applications
DescriptionVariable
svainit sets this variable to :0.0. This value changes
temporarily when DMX servers start.
DISPLAY
svainit sets this variable to 1 to avoid GCONF problems that
cause the display node X Server to crash. Do not modify this value.
GCONF_LOCAL_LOCKS
The job ID of the current allocation.SLURM_JOBID
svainit sets this variable to the location where Job Settings Files
are stored. Do not modify this value.
SVA_JOBS
svainit sets this variable to the location where the DMX
configuration files for each Display Surface are stored. Do not
modify this value.
SVA_DMX_CONFIG_PATH
svainit sets this variable to the name of a temporary file that is
used for svagetdata and svaputdata before a job is
allocated. Do not modify this value.
SVA_TEMP_DATA_FILE
svaAllocateJob sets this variable to the condensed list of
display, render, and compute resources requested for a job. Do
not modify this value.
SVA_Allocate_Hosts
This internal variable is initially set to 0 and later set to 1 to
indicate that cleanup is complete. Do not modify this value.
SVA_Cleanup_Complete
This variable is initially set to 0. However, if
SVA_COMPUTE_COUNT is specified in the User Configuration File,
SVA_Compute_Count
it is set by svaGetJobDefaults. It can also be set by the
command line argument -c in some scripts; for example,
sva_job_template.sh.
Before the job is allocated, this value is used to request computing
resources for a job. After the job is allocated, it is used to control
job steps to computing resources.
The variable value is also stored in the Job Settings File, SVA_JOB
section, SVA_COMPUTE_COUNT tag. Do not modify this value after
the job is allocated.
svaAllocateJob sets this variable to the condensed host names
of the compute hosts allocated to the job. This value is also stored
SVA_Compute_Hosts
in the Job Settings File, SVA_JOB section, SVA_COMPUTE_HOSTS
tag.
This variable is initially set to 0. However, if SVA_RENDER_COUNT
is specified in the User Configuration File, it is set by
SVA_Render_Count
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.
svaAllocateJob sets this variable to the condensed host names
of the render hosts allocated to the job. This value is also stored
SVA_Render_Hosts
in the Job Settings File, SVA_JOB section, SVA_RENDER_HOSTS
tag. Do not modify this value.
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
SVA_Display_Count
in the Job Settings File, SVA_JOB section, SVA_DISPLAY_COUNT
tag. Do not modify this value.
