Frequently Asked Questions

I don’t have SSH or VNC installed – where do I get this software?

  • PuTTY is an open source SSH client software and can be downloaded from http://www.putty.org/
  • VNC is a remote control client software that is supported on VCL images. It is available for purchase from http://www.realvnc.com/

The OREC does not have the software I need. Can additional software be added?

  • It is possible to include additional software packages in VCL images; however, it is important that licensing limitations are not exceeded.

What happens if I leave my work on a VCL desktop?

  • Images are reloaded at the end of each reservation. As a result, all user created data will be lost if you do not copy the data off of the virtual desktop at the end of your session.

How do I copy data from a virtual desktop?

  • You will need to use a Secure Copy (SCP) program to copy files from the VCL desktop. If you are using a Linux or Mac computer to access the virtual desktop it will have an existing SCP client installed. If you are using a Windows computer to access the virtual desktop you will need to install a Windows SCP client, such as WinSCP.

I forgot my password to a virtual desktop that I have reserved. Where can I lookup the password?

  • Login to the VCL website. From the menu on the left hand side of the page, click Current Reservations => Connect. Your credentials will be displayed.

How much computing power is available in the OREC?

  • We currently have approximately 448 cores (28 blades each with 16 cores running at 2.2Ghz ) and 1.7TB RAM (28 blades each with 64GB RAM). There is no ‘big storage’ service provided through OREC. Researchers are encouraged to mount external storage to each node once the node is available.
