- This week we performed severe maintenance in the cluster: we migrated the shared FS from Lustre to GPFS. So far, the performance of GPFS is way better than Lustre thanks to the usage of SSDs for the metadata. We also updated the firmware of the controllers and systems running GPFS. - Update of Argus packages to latest versions. - Update of CREAM-CEs to latest versions. - Upgraded 10 Supermicro WNs to the new AMD 16 core CPU. So, in total, we have 10x32core machines plus all the old Sun WNs. Unfortunately we were unable to boot them with the SL5.5 kernel and so we're upgrading them to SL5.7 with the latest kernel (this means recompiling infiniband and gpfs drivers). It's taking more time than expected to deploy these servers, but once done, this would mean 80 cores more with approximately the same power consumption. - Fixed some issues with the site bdii publication system (outdated publishing).
Unfortunately we are still seeing issues with CREAM services (mostly scp failed transfers and problem with all pool accounts used)
