March 29th: Easter update
The weather seems to have improved so maybe spring is on its way after all.
Introducing lovelace: Nine years ago, before we went down the managed cluster computing route, all Linux compute servers in Maths were essentially stand-alone systems that anyone could use interactively, logging in via ssh, running programs from the command line and using X forwarding over ssh to run GUI programs such as xmaple and Matlab. The move to batch-mode cluster computing has removed this facility which has disadvantaged users who don't want to learn how to use the cluster and short term visitors alike, so this new addition will restore the ad hoc compute facilities we used to have. With 4 CPUs, 64 processor cores and 512 GB of memory, there should be enough compute resources for all. More info
SCAN running full-time in Huxley 410 over Easter: running full-time in Huxley 410 from 8pm Monday March 26th until 05:50 on Monday April 30th except for a 7.5 hour maintenance window every Thursday morning between midnight Wednesday and 07:30 on Thursday morning. This is to allow ICT to carry out routine weekly Windows updates and system maintenance and the systems will reboot back into SCAN mode just after 07:30am on Thursdays.
Only one node remaining in legacy cluster: macomp17 from the legacy cluster has been taken out of service, upgraded and moved across campus to join the NextGen cluster, leaving just one compute node, macomp14, remaining while an existing user job completes. The Nextgen cluster is running well and as spring approaches, usage is expected to increase.
A dedicated MySQL server has been introduced to meet the demand for a higher throughput server for projects co-hosted between Maths and other departments. This will replace the MySQL service provided by macomp00 which was originally added as an afterthought to this server to meet a project requirement from Bioinformatics that has since grown far beyond the original expectations. Fittingly, the new server is called mysql.ma and the existing macomp00 facility will remain in place for the forseeable future while users with legacy databases on it decide what to do with them.
Other news: a number of projects for several research groups have just been started - more info to follow when there is more to report.
