System Status: UP and DOWN
We continue to experience random outages of the system. Network problems are the latest suspect. All/most GPC jobs died at around 2:40pm today.
We are still encountering problems resulting from the transition to CentOS 6. While we had tested this operating system on a subset of nodes, there are problems when running at large scale, i.e. with almost 4,000 nodes in the GPC cluster.
Please bear with us as we try to fix things. Some of the symptoms are evidenced in the slow (or disappearing) filesystems, sluggish nodes, and general network problems. We'll inform users when we've solved this. In the meantime, please check this space regularly for updates.
Some of the known issues (and workarounds) are listed here.
Thanks for your patience and understanding!
The SciNet Team.
The GPC has been transitioned to CentOS 6 on Monday, December 5, 2011. While this should not have influenced running jobs, unexpectedly, the scratch and home file systems got unmounted on Monday afternoon, killing most jobs. Please resubmit.
Let us know if you encounter unexpected behavior due to the transition.
