RRC Scale Out

The management system for the research cloud has beened "scaled out" from 1 node to 3 nodes.  This should improve performance and reliablity as well as allowing future updates to be applied without service interruption....

Cronjobs on the Academic Computing Cluster

A dedicated Virtual Machine (VM) is now provided to run cronjobs on the Academic Computing cluster. See: Academic Computing Cluster User’s Guide and Cronjobs on the Academic Computing Cluster. Please note, to be able to connect to the cronjob node directly you need to connect to cluster.act.rdg.ac.uk first, just once. This will register you account as a RACC user....

Free Cluster available for testing

The Free Cluster is available for testing. A draft user guide can be found here (the document will be updated as testing progresses). The Free Cluster has a number of login nodes which can be used to submit batch jobs and for interactive computing as well, and over 200 CPU cores for batch jobs. Sessions on the login nodes are load balanced and automatically scheduled when you connect to the cluster (no qrsh needed). These login nodes can be used for interactive computing, on similar terms as the interactive nodes in met-cluster, and these login nodes have now more memory than the interactive nodes on met-cluster. Some popular applications including Matlab, IDL, python, and compilers are already installed and available via the module command. Further applications and libraries can be installed as required. In batch mode user jobs are isolated and allocation boundaries are strictly enforced. It will prevent oversubscribing resources, runaway processes and will minimize negative impact that incorrectly submitted jobs can...

New Home Directories

On Tuesday the 5th of June the Academic Computing team will be migrating all Unix home directories to a new location to offer greater performance and scalability. As standard all users including staff and students will have a default quota of 10GB and this can be increased with a simple request via the IT Service Desk. To help with the transition we will be mounting the new home directories under their new home under /home/users/%username%. On the 5th of June we will need to take all Unix Systems offline to mount the new home directories and complete some migration tasks. Services affected include: Met-Cluster Maths-Cluster Free-Cluster NX-Managed Desktop Linux VMs hosted on the Research Cloud...

short network outage in Meteorology on 20th March 2018

Essential work needs to be performed on a core networking device. Due to this, users within the Meteorology building and IT/Maths will see an outage at roughly 18:05 on the 20th March, lasting up to 10 minutes. Please log out by 6pm on Tuesday evening to avoid data loss, as home directories will not be available during the network downtime. Please contact IT through the usual channels in case of any problems....
