To use the dedicated visualiation nodes ensure that any
commands run reference
--partition=visual for full hardware
acceleration. For other visualisation tasks that do not require
hardware acceleration any compute partition
can be used.
For more information on partitions see Partitions .
To get the best from the visualisation nodes you need to use the hardware
acceleration of the nodes. For some packages this means using the X
Windows server on the node by setting the option
-display :0 on the commands run to make it use the
hardware accelerated X Windows display that is running on the node. For
applications such as
this then allows the
client-server operation to silently use the hardware acceleration then
relay the information back to the user in real-time. This is as it has
been set up to do so without the need for special system-level
permissions to use the hardware, but allowing the current user and only
the current user with a job running on a node access to the X Windows
system for the duration of the job.
If for some reason you need to render on a node without hardware
acceleration then you can start up a dummy X Windows server to use by
prepending commands with
