2013: Summer update

Just a catch-up on what has been going on since the spring update:

  • Huxley 616 server room: to cope with increased demand for UPS power in the server room, one of the older 5 kVA UPS units was replaced by a new 8 kVA unit towards the end of June, with the older unit being kept as a spare with its batteries kept on trickle charge.

  • compute facilities: A gradual move to a Ubuntu-based computer cluster has begun with the addition of the two new nodes macomp12 and macomp13 along with the rebuilding of macomp000 and macomp01 as Ubuntu Linux machines. Running the latest Ubuntu Server version 13.04, all four nodes have the latest available versions of the same range of software as installed on the existing Red Hat Linux-based cluster nodes along with some new additions such as the Gerris suite, etc. macomp12 and maciomp13 feature hex-core Xeon CPUs providing 12 processor cores in each node along with 48 GB of memory. New, larger queues will be created soon to support larger jobs - users wishing to use the Ubuntu-based part of the Maths compute cluster should include the directive:

    #PBS -q ubuntu_standard

    in their job submission script to ensure that it runs on the Ubuntu-powered nodes only, and not on the default 'standard' queue which executes on Red Hat-powered nodes.

    More information about the cluster migration can be found in the cluster job queueing pages

  • The LFC-UK project cluster has now been fully expanded with the addition of two more server blades.
