Table 2-1 Environment Variables for Running Applications (continued)
DescriptionVariable
This variable is set to the value of SVA_PARTITION and
is prefixed with -p. It can also be set by the command
line argument -p in some script; for example,
sva_job_template.sh.
This variable is used on all SLURM command lines to
specify the SLURM partition to use for allocating and
running jobs.
SVA_Partition_Name
This variable indicates that the tiles attached to a single
display node are arranged horizontally (value equals
.horizontal), vertically (value equals .vertical), or
in an n x n arrangement of four tiles only (value equals
.square). Set it to an empty string if there is only one
tile for the display node.
SVA_TILE_ORIENTATION
svaAllocateJob sets this variable to the sum of
SVA_Display_Count, SVA_Compute_Count, and
SVA_Render_Count. Do not modify this value.
SVA_Total_Count
This variable is initially set to null. However, if
SVA_TILE_GEOMETRY is specified in the User
Configuration File, it is set by svaGetJobDefaults.
This variable selects the display tile geometry when
starting X Servers on the display hosts; for example,
1024x768; 1280x1024; or 1600x1200.
SVA_Tile_Geometry
This variable turns the X cursor on or off on the display
node. 0 sets the cursor to appear on nodes; 1 sets the
cursor to not appear on nodes.
SVA_UNCLUTTER
This variable is initially set to 0. It is set to 1 in
svaValidateOptions if inconsistencies are found in
the job options.
SVA_Usage_Error
This variable is initially set to 0. However, if
SVA_USE_DMX="yes" is specified in the Site or User
Configuration File, then SVA_Use_DMX is set to 1. It
enables/disables DMX on the execution host.
SVA_Use_DMX
svainit sets this variable value to 0. Set it to 1 to enable
verbose output.
SVA_Verbose_Flag
This variable is initially set to 15 seconds. It is used to set
a sleep period after starting the X Servers to give them a
chance to start up before continuing.
SVA_XServer_Delay
This variable is initially set to startx. If DMX is used, it
is set to xinit by svaGetJobDefaults.
SVA_XServer is used by svaRunDisplayXServers
to start the X Servers on the display hosts.
SVA_XServer
This variable is initially set to the value of the
SVA_X_OPTIONS tag in the SVA_JOB section. It is used
to pass extra options to the X Servers when they start.
