March 24th: spring 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

Two more nodes from the legacy cluster have been taken out of service, upgraded and moved across campus to join the NextGen cluster, leaving just 2 compute nodes remaining while existing user jobs complete. 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.
