Lion-XG Transition Information

To transition Lion-XG users to the new ICS-ACI system, ICS has created a migration plan. Read on for details about the plan, information about the transition process, and key dates. 

Migration Plan 

  • ICS will make available a liaison who will provide technical/consultative support to PI groups transitioning from Lion-XG. 
  • The Lion-XG system will be shut off on December 21, 2017. 
  • PIs who have queues on Lion-XG or have Group storage allocations will receive Try-ACI allocations for compute and storage: 
    • The compute allocation will be equal to the PI’s documented Lion-XG core total, rounded up to the nearest 20-core block. It will last four months. 
    • The storage allocation will be equal to the PI’s documented storage total, rounded up to the nearest 5 TB block. It will last twelve months. 
  • Lion-XG users who also use other legacy resources will have all of their resources transitioned at once. Your liaison will have more details on how the transition of your other resources will proceed. 

Transition Process Steps 

1. Submit Intake Form

PIs will fill out an intake form and submit it to ICS by August 4. The purpose of the intake form is to gather information about your usage of Lion-XG, such as when you are available to transition, the members/collaborators of your PI group, whether you possess controlled data like dbGAP, and what software packages your group requires. Your liaison will use this information to help you transition smoothly. Please fill out the entire form before submitting. 

2. Request and Activate Accounts

All users transitioning to ICS-ACI will need a new account to use the system. Learn more about requesting accounts here. When you submit your request, ICS staff will create and activate a new account for you. Users need to have active accounts prior to onboarding, so please request an account now. 

3. Sign SLA

If the PI has cores documented on Lion-XG, the PI will sign a Service-Level Agreement (SLA) for a Try-ACI compute and storage allocation. 

4. Transfer Storage

ICS will transfer the PI’s Group storage directory to ICS-ACI using the rsync tool. Users are responsible for transferring any Home, Work, and Scratch files that you wish to keep. ICS will not transfer files in your Home, Work, and Scratch directories. If you require assistance in transferring files from your Home, Work, or Scratch directory, please submit a ticket to the ICS i-ASK Center.To speed the movement of your data, please consider 

  • including only files that you need to be transferred on your Group Directory when ICS transfers your data; 
  • organizing your files into separate directories; and 
  • compressing many files into a single .tar or.zip archive 

5. Onboard to ICS-ACI

ICS will work with the PI groups to get them up and running on ICS-ACI. This includes 

  • onboarding sessions to orient new ICS-ACI users to the system; 
  • assistance with software compilation; and 
  • “smoke-testing” codes for operation on ICS-ACI. 

NOTE: Onboarding sessions will cover essential tasks such as logging in to ICS-ACI, accessing your storage, and submitting jobs to the Open Queue or an allocation. Users are strongly encouraged to attend these onboarding sessions.

6. Sign Off on Transition Completion

After onboarding, the PI (or a designated representative) will sign off by contacting their liaison and confirming that the PI is able to compute on the new system. At this point, ICS will remove the group’s access to Lion-XG.
