5.7.2 Use the Framelock Script Function

If you write or modify job launch scripts, there is an SVA scripting function (found in svainit)

to enable framelock on a Display Surface:

svaEnableFrameLock

For an example of how to use this function, see /opt/sva/samples/sva_job_template.sh.

See the SVA Visualization System Software Reference Guide for more information on all the scripting

functions, including svaEnableFrameLock.

5.7.3 Use the Framelock Utility

SVA also has a utility called svacontrolframelock to turn hardware framelock on and off

at any time. It is particularly helpful when used in the context of an SVA job.

Examples include the following:

To turn on framelock for nodes n1, n2, and n3:

% svacontrolframelock n1:0 n2:0 n3:0

To turn off framelock for nodes n1, n2, and n3:

% svacontrolframelock --disable n1:0 n2:0 n3:0

See the SVA Visualization System Software Reference Guide for detailed information on the syntax

for svacontrolframelock.
