svaRunDisplayXServers(3)
svaRunDisplayXServers
svaRunDisplayXServers -- Starts X servers on the job's allocated display hosts.
Synopsis
svaRunDisplayXServers [ -nowait ]
Parameters
-nowait Runs the X Servers in the background on the display hosts; does not wait for the X Servers to
complete before returning.
Returns
None.
Description
Runs an X Server on all display hosts allocated to the job. It waits for the command to complete before
returning, unless the -nowait option is specified.
After the X Server starts, turns off power management and any screen savers that can interfere with the
visualization aspects of the job.
If –nowait is specified, it sets SVA_DISPLAY_XSERVER_JOBSTEP to the job step for the X Servers. This
makes it possible to wait for them using svaWaitForJobStepToFinish. If the data configuration tag
SVA_USE_REMOTE3D is defined to be non-zero, gdm is used. The user must log in before the job acts on
the X Server.
Make sure the job launch script sources the svainit file before this function is called:
. svainit
