Introduction

VISIT is installed on selected fedora based SHARCNET workstations for remote graphical application usage. VISIT is not currently installed on the new Compute Canada clusters graham and cedar. If it is needed, please email help@sharcnet.ca and request it. Also, please see the Visualization page on docs.computecanada.ca for additional information about visualization on Compute Canada systems.

Version Selection

The visit command should be found your path by default. Otherwise it can be started by running:

/usr/local/bin/visit

General Notes

Graphical Connection

To establish a remote graphical connection to any of the sharcnet visualization systems where VISIT is installed, we recommend using the Web Browser (noVNC) method described in https://www.sharcnet.ca/help/index.php/Remote_Graphical_Connections

Client-Server Connection

To establish a remote client-server connection between your local computer and the SHARCNET visualization systems where VisIt is installed, we recommend to check which version is installed in the visualization system and then download that version for your local computer.

vdi-fedora23 + MacOS X

vdi-fedora23 has VisIt 2.12.1 installed. Once you download that version on your MacOS X, then you go to the Options menu ==> Host profiles ..., you are going to get a window dialogue, where you will have to fill it as following,

You will have to click on New Host. Then a new line will appear in the Hosts list on the left side of the window.

  • Host nickname: vdi-fedora23
  • Remote host name: vdi-fedora23.user.sharcnet.ca
  • Path to VisIt installation: /usr/local/visit2_12_1.linux-x86_64
  • Account: your_SHARCNET_user_name
  • Enable Tunnel data connections through SSH
  • Enable SSH command: ssh
  • Enable SSH port: 22

Then click Apply.

Then choose Launch Profiles tab, and click on New Profile. Note that it will create a new Launch profile and automatically VisIt will put you inb the Settings tab.

  • Profile name: vdi-fedora-23_profile
  • Timeout (minutes): 480

Now go to the GPU Acceleration tab,

  • Enable Use cluster's graphics cards
  • DISPLAY: :0.%l (note that you have to only add a 0. between the : and % in the default value.)
  • Number of GPUs per node: 4

Then Apply again. Finally, you Dismiss. Don't forget to Save the changes Go to Options menu ==> Save Settings. Then you must restart your VisIt version.

Once you open VisIt again, you will be able to choose data from the remote server, then go to File ==> Open File ==> Hosts and choose vdi-fedora23.

Now you should be able to fully use your data from SHARCNET and use vdi-fedora23 as a compute engine.
