The VIZ is the GUI interface at the Center for Research Computing. In this document, we present all the information you need about VIZ.
Here is the table of contents:
- Access to VIZ
- Off-campus access (setting up the VPN)
- On-campus access
CRC computational resources are housed off campus at the University’s main data center. CRC clusters are firewalled, so you can not directly access them when you are off-campus.
If you are off-campus, the cluster is accessible securely from any where in the world via a Virtual Private Network (VPN), a service of CSSD. The VPN requires certain software to run on your system, and multiple alternatives are available in order to cover almost all systems and configurations.
Download/Install Pulse VPN and follow the instruction as follows:
VPNC is a commandline VPN application which may be the most convenient way to connect for some Linux users.
Most distributions provide prebuild binaries, or you can get the source and install your own:
- Ubuntu: sudo apt-get install vpnc
- SUSE: sudo zypper install vpnc
- CentOS/RedHat: sudo yum install vpnc
- Arch Linux: sudo pacman -S vpnc
- All (source): http://www.unix-ag.uni-kl.de/~massar/vpnc/
Once installed, download the configuration file here (requires login) and move the file to /etc/vpnc/pitt.conf. Then:
- Adding your username and password and delete YourPittUsername_HERE and YourPittPassword_HERE.
- Run sudo vpnc pitt, to stop, run sudo vpnc-disconnect
- Disconnect will kill most recent vpnc
- Kill all of them with sudo killall vpnc
To access the VIZ GUI, simply open a web browser and go to https://viz.crc.pitt.edu/. Then login with your Pitt username and password. You can treat this machine as another login node with extra capability to access to GUI interface. You can also submit jobs to H2P (refer to H2P documentation for more info) using VIZ machine. Below, I provided snapshots on how to access and use VIZ.
