August 18th: NextGen HPC cluster is back online, all GPU servers now available along with most other systems hosted in Maths server room, relocation of GPU network & clustor4 from Huxley to ICT data centre scheduled for next week
NextGen HPC: this is now back up and running with the operating system on all nodes upgraded and many software packages have been updated to the latest available versions. The management node was damaged during May's power incident and has been replaced by a newer server while the main submission node, macomp001, will shortly be replaced with a server identical to macomp002, fitted with newer CPUs that support the Intel AVX and AVX2 instruction sets, matching all of the other Intel-powered compute nodes. For now, please use macomp002 instead of trying to use macomp001 until the new macomp001 is installed.
Three of the compute nodes are offline for the time being awaiting replacement of failed memory DIMMs but this will not affect the cluster as a whole. Also, there are possible issues with the latest version of Matlab 2026a which is now being actively investigated.
Relocation of GPU network: with all the main GPU servers now moved over to the CAGB data centre, the clustor4 GPU user data storage server and the associated 10Gbit/s local network will be moved here as well within the next weeki although data stored on clustor4 is already accessible now via the College network. clustor4's mirror server, clustor4-mirror, will remain in Huxley for better data resilience.
