Overall strategy

Upgrade cluster's OS and add 2 new compute notes. Very similar retro-fit as we did with Collum's system this summer

Broad steps

Top Level Task Description

Effort Est.

Assignee

Keep cluster running until cut-over noted below.

 

 

Pull an existing, old compute node from Lancaster's cluster and convert it into a new head node.

 

 

Install new OS

 

 

Add a new compute node (from Crane) to this new head node.

 

 

Pull another existing, old compute node from Lancaster's cluster and test it mounts to new head node.

 

 

Test new head node with 2 new compute nodes (from Crane), and old compute node

 

 

Cut-over accounts and data from old compute node to new compute node.

 

 

Move the rest of Lancaster's old compute nodes to the new head node.

 

 

Confirm all is working.

 

 

Convert old head node into a compute node.

Current and recent activity and decisions

8/27/13Tue: Oliver met with Brian Crane

  • Brian Crane graciously agreed to wait, allowing ChemIT to start and focus on Hoffmann's new cluster instead.
  • Crane will email Kyle Lancaster with an update. Plan is to move forward with retrofit of Lancaster's cluster (new OS), pending Kyle's approval. See above for more details. No need for interim solution from ChemIT.
  • Oliver to meet with Kyle to review steps and timing in more detail.
  • Having come close to completing Collum's cluster retro-fit, Oliver estimates Lulu being able to start in ~8 weeks. BUT, we can and should start work with Brian and designates much earlier (4 weeks earlier!) to spec and order hardware so it can be ready for Lulu to work with in ~8 weeks.
  • Oliver to provide Crane a status report every 2-3 weeks, until we start
  • Idea: Have Lulu install SBGrid on Lancaster's cluster so Crane's group can test. This might help inform hardware spec if bottleneck(s) identified using Lancaster's current compute nodes.
    • Oliver to discuss this idea with Lancaster. Then, determine when Lulu would have time to invest in this installation.

3/4/13: First meeting, Crane and Oliver. Characterize needs, explore some alternatives, and define next steps.
