Hi Steve
Thanks for the confirmation. I already included the Liverpool information in my message to the VO admins list.
All
On Tuesday we discussed getting the non-LHC VOs to start testing their jobs against EMI-2 WNs and one view was that due to a shortage of manpower they would probably not have time to do much testing against our dedicated queues (especially if they needed to setup software on them). The approach now being adopted by the Tier-1, which is quite a good one, is to add a few of these EMI-2 SL5 nodes to the production queues so that they get sampled with regular job submissions. We can then review which VOs have been seen to run successfully or otherwise on these small number of nodes (and thus very low associated failure rates if there is a problem) and feedback to the VOs where we see problems. This more pro-active approach is a good compromise between catching problems too late when everyone is moving anyway to EMI-2 SL5 and the current situation where dedicated clusters are little used for testing (I know they have just appeared!).
Any comments or concerns with this approach, particularly in terms of the implementation, would be most welcome.
Many thanks,
Jeremy

It's set up the same way as our main cluster, with the same VOs etc. The only difference is that it is very small and that it runs EMI2. Anyway, here are the coordinates in case anyone (or anyvo!?!) wants to use it.
