7 Methods of Remote Access SSH Command-line interface, useful for managing files, submitting jobs, etc. Direct VNC connection Command-line submission, separate VNC client TACC Visualization Portal Simplified web-based interface for submitting and interacting with remote vis sessions

8 SSH Access Start the Secure Shell Client application Start->All Programs->SSH Secure Shell Click Quick Connect Host Name: maverick.tacc.utexas.edu User Name: <your account> Click Connect

9 SSH Access You re now on a Maverick login node Can run usual shell utilities Manage data, etc.

10 SSH Access Submit a remote vis VNC job: Set a VNC password (one time only): vncpasswd sbatch /share/doc/slurm/job.vnc geometry 1280x800 Monitor job status: showq -u touch vncserver.out tail -f vncserver.out Connect to address in output file with a VNC viewer

11 VNC Clients Recommended: TigerVNC Some other clients TightVNC (Windows, Linux) Safari / screen sharing (Mac OSX) vnc://maverick.tacc.utexas.edu:<port>

12 Connecting to a VNC session Cut and paste the VNC address + port (maverick.tacc.utexas.edu:port) Launch TigerVNC viewer

13 Available So6ware module avail

14 Running ParaView module load qt paraview vglrun paraview

15 Quitting the session exit from the original shell terminal Or, from login shell: showq -u scancel <job ID>

16 TACC Visualization Portal A web-based interface that lets you: Submit jobs Interact with remote VNC sessions For many users this can be the primary method of interacting with Maverick Advanced users may still use SSH In the future this will work for all TACC vis resources

17 Login as a TACC user with your training account (Safari or Firefox)

18 Start a VNC job (Desktop resolution: 1280x800)

19 First time only: Set a VNC password

20 First time only: Set a VNC password

21 Start a VNC job (submit again)

22 VNC Desktop

23 Running Vis Applications through VNC To see available applications: module avail Examples: Run ParaView: module load qt paraview vglrun paraview Run VisIt: module load visit vglrun visit

24 Accessing your VNC session with a stand-alone viewer (or share your session with others) Navigate to the Jobs tab Mac users: Click the vis.tacc.utexas.edu link to open the remote desktop viewer Others: copy the address (vis.tacc.utexas.edu:<port>) Launch VNC viewer and connect to that address

25 Connecting to a VNC session Cut and paste the VNC address + port Launch TigerVNC viewer

26 Parallel Visualization You can specify how many nodes (and processes per node) to use during job submission Run vis applications in the parallel environment
