Research and Teaching Unit Three Year Spending Plan

Spending plan for the Research and Teaching unit for financial years 2011/12, 2012/13 and 2013/14 under two funding scenarios where the entire computing budget for the next three financial years is either 100k/50k/100k or 100k/0k/100k.

This spending plan assumes that a virtualisation service (KVM) will continue to be provided (sufficiently resourced and funded) outside of the Unit. The unit is already extensively virtualised, physical servers that exist are there purely because of particular performance requirements.

Planned spending total is effectively so low that there is not any significant difference between the two scenarios.

We will need to add a bit of star-gazing into the above as this just assumes ongoing continuance of all existing services.

Beowulf:

In 2012 the compute nodes will be 5 and 6 years old, at some point they will start to fail and we will have to replace them or bin the cluster. The cluster continues to be used for gridengine jobs which for various reasons can't be done on eddie the same compute nodes are part of the hadoop cluster which is used by a number of researchers and the Extreme computing course.

I do not believe the clusters in their current form are sustainable, assuming we wish to keep this functionality I believe we should:

  • repurpose equipment which has come out of other use (this has been done with the PE750s which act as GPFS servers)
  • replace nodes on an affordable basis ( 2-3K/year) with cheap rackmounts or desktops
with a view to retaining about the same number of cores on a reduced number of nodes. We are currently looking at ways to cut the power useage of the cluster (BeowulfPowerReduction) and replacing older kit would help with this
