Hardware Accelerated GUI Sessions

Currently in Beta Test

Please note that these scripts and instructions are temporary for the duration of the beta test. launch_hwgui* will likely be integrated into the existing launch_gui_sessions scripts as an argument at a later date.

Launching Hardware (HW) Accelerated GUI software

Load hidden HW GUI beta module:

module load hwgui

Launch application with default resources (trackvis for this example):

launch_hwgui_trackvis

You should get an output of the following form:

Session: c11a-s33.rc.ufl.edu:9830 for HW-Track job 6681209
Copy this command to a terminal on your LOCAL PC:
xpra attach ssh:testusr-1234@c11a-s33.rc.ufl.edu:9830

You can then copy and paste the connection command to your LOCAL PC and connect to the hardware accelerated version of the application. Please see the section below for more information on connecting.

Other applications currently included in the beta:

launch_hwgui_freeview

launch_hwgui_matlab

The launch scripts also support the normal additional resource parameters (e.g. processor count, memory, etc):

[testusr-1234@gator3 vgl-test]$ launch_hwgui_freeview -p 2 -m 40
Verifying SSH setup for 'testusr-1234'

Starting hwfreeview under Xpra in a SLURM gui session.

Requested hwfreeview memory size: '40gb'

Requested '2' processor cores

Requested '8' hours for the session

Please use the -h argument to see more information on what additional parameters are available.

Connecting from your local PC

Connecting from your local PC is the same as a normal GUI session, you can run xpra_list_sessions to find your running gui jobs:

xpra_list_sessions
