2.1. Progress Summary

The UK NGI suffered two major power outages in Q11. The second outage, which was caused by voltage surges at the time of electrical maintenance work, resulted in a significant number of hardware failures. All services were brought back online in a timely manner and critial procurement of new hardware was enabled in a very short timeframe. The first incident was due to failure of the UPS generator to provide sustained power due to a power failure. Since then the issue with the generator has been found, addressed and tested.

The UK community has been working closely with EGI Operations to provide a WN tarball for EMI with the decommissioning of glite WNs.

The UK NGI is exploring opportunities for sustainability post EGI InSPIRE and has successfully bid into the EGI Miniproject proposal call.

2.2. Main Achievements

Procurement of resources to meet 2013 WLCG MoU commitments on track. Hardware delivery partially complete. Upgrade of batch farm to EMI-2 complete, more generally EMI-2 rollout on all services close to completion. FTS 3 testing continues. Test queues available for SL6 on batch farm. CVMFS Stratup-0 available for small VOs – currently working with NA62 and Mice. Change to batch farm configuration, hyperthreading now switched on and running more jobs than cores (cpu normalisation/accounting appropriatly adjusted). Preperation to upgrade Tier-1 network backbone underway and likely to be scheduled for early Q2.

Imperial College has continued to maintain and develop the UK 'state of the nation' web-pages ( and tracking the roll out of EMI services in the UK. We submitted an EMI2-CREAM staged-rollout report and elsewhere in London UKI-LT2-Brunel submitted an EMI2-WN staged rollout report. We've also been helping UK sites to transition away from Glite to EMI. We have been contributing to the ROD rota. Now that an EMI tarball has become available we have been testing this at our site and sent feedback to the developer.

gLite 3.1 retirement went without any problems at Glasgow. gLite 3.2 retirement is on target to remove all services before the end of January - with the majority of services moved to the EMI-2 release. DPM file balancing software being developed to alleviate issues with disk hot spotting.

Alessandra Forti (MU) is now part of the WLCG middleware deployment and perfsonar deployment coordination task forces. Andrew has made three trips to CERN to undertake LHCb Grid Production shifts, to train for LHCb Grid Expert On Call (GEOC) shifts, to work with the ops team and LHCb DIRAC developers to produce site-orientated views of the LHCb job/site monitoring to make it easier for sites to resolve problems with LHCb jobs, and to begin co-ordinating a review of the DIRAC system and its interoperation with sites and resources in preparation for Long Shutdown 1 and the LHC and LHCb upgrades. Robert Frank has continued to work on updating the GridPP/NGS VOMS system as it transitions from NGS to GridPP operations. He and NGS Support Centre Manager are co-ordinating this with VOMS backup installations being set up at other GridPP sites (Oxford and Imperial).

Oxford, leading the Federated Cloud Task Force in EGI report that the integration of cloud resources into the current EGI production infrastructure is proceeding as planned. Three new types of endpoints have been created within GOCDB and the resource providers that are contributing resources to the federation test bed of the task force are now registering their OCCI, CDMI and accounting endpoints. A SAM instance dedicated to cloud resources has been deployed. Data is retrieved from GOCDB and the state of the federated cloud resources is monitored thanks to a set of dedicated probes. Furthermore, the profile we created for the accounting usage records is undergoing a peer-review updating process while the cloud accounting infrastructure is being merged within the EGI production-grade APEL service. The integration of cloud resources within the EGI infrastructure is completed by making available two general-purpose OCCI clients that will allow every EGI user to access federated cloud resources in a transparent and standardised way. Two use cases have been successfully supported via the federated test bed and two more are in the pipeline. The work planned for the coming months include the set up of multiple demo for the upcoming EGI 2013 Community Forum in Manchester; the opening of the test bed to generic users; the use of the federation test bed as the back-end for multiple scientific portals

2.3. Issues and mitigation

Issue Description Mitigation Description
Two major power incidents at STFC RAL caused considerable disruption and in the second case hardware damage and severely impacted availability (SiRs available) All services were brought back up efficiently and the incident confirmed procurement was possible at very short timescales
Stability problems with the (EMI-2) top level BDII trying an upgrade to SL6 to see if that addresses the issue
Tarballs We are still waiting for suitable glexec and UI tar balls
(Fed Clouds) relative lack of capabilities exposed by the available implementations of the OCCI management interfaces establishing a close relationship with the development communities of the OCCI implementations
(Fed Clouds) supporting established user communities with a federation test bed as opposed to a production-grade federation of clouds managing the user expectations and, more importantly, by involving the EGI technical support unit within the task force operations
(Glasgow) Ongoing issues with damaged Air Conditioning units Full engineering review of data rooms 141 and 243d to redesign power delivery and air conditioning flows
