Getting Started with Rogues Gallery¶
How do I request an account on the Rogues Gallery (RG)?¶
Users should request a new account using our form on the CRNCH page here. Note that it may take 2-3 business days for your account to be added after you are approved.
For both internal and external users, we ask for “an RG contact”. If you’ve talked to one of the key personnel for the RG testbed you can put this person down, or you can put down your research advisor if you are external to GT but working at a university.
For GT users, please put your research advisor or down one of the testbed personnel you have talked to. We will also need your GT (Passport) username to add login access for you.
NOTE: For GT faculty or staff looking to add new external users, it is very helpful to us if you can sponsor the users as Passport guests. Then the above form can be filled out with the external user’s guest username which helps to streamline the access process. You can sponsor a guest account with Passport for up to one year and then renew the user if they are still an active collaborator.
How do I Access RG machines?¶
NOTE: You should use your GT Passport username and password to access all CRNCH RG nodes and resources!
To access Rogues Gallery machines from off campus you need to 1) SSH to testbed nodes or 2) use a GUI tool like X2Go or VNC. For SSH, you should use your Georgia Tech account username and password to log into all nodes using the gateway login node, rg-login.crnch.gatech.edu. rg-login is available from off the campus network and the VPN, and other nodes are accessible from the login node.
Some of the Rogues Gallery machines include:
Note that all machines have a .crnch.gatech.edu suffix and some examples include:
- rg-login login VM for off-campus access. Used as a gateway node
- rg-emu-dev: VM for Emu compilation and simulation
- rg-fpga-dev-<1-4>: VMs for FPGA compilation and simulation
- rg-neuro-dev: VM for neuromorphic tools
- Please see this page for a complete list of available machines in the RG testbed
What’s this about the VPN?¶
You can access all CRNCH resources using login nodes like rg-login. However, you can also use GT’s VPN solution as an alternative to access VMs and nodes directly. Note that this may require that you set up two-factor authentication on your phone and link it with your account name. You shouldn’t need to use the VPN to access Rogues Gallery resources and materials, but for special requirements please email us at crnch-rg-help@cc.gatech.edu.
Using the Georgia Tech VPN¶
Other Georgia Tech resources like PACE’s Phoenix cluster require the usage of the VPN.
How do I work with novel architecture of interest X?¶
First of all, check the sidebar for the appropriate architecture category and read through the existing documentation. Note that we are migrating some of our pages from our internal wiki to this public ReadTheDocs site over the next few months. You can use your GT username and password to log into the internal wiki.
Once you have done this, if you have questions please ask on Teams or via help ticket.
What are some best practices for using the RG hardware?¶
- Make sure to back your code up, preferably with a GT Github or external Github repository. While we do have a shared filesystem, this can possibly experience a hardware failure.
- Use tmux or screen on the login and development VMs, especially when running tests.
