Job Code	IT139

Description	A world-wide federation of hardware resources must be used for physics data analysis in the LHC experiments because of their huge processing and storage capacity requirements. The new foundation for computing for High Energy Physics will be based on GRID middleware which is currently being developed in the context of EGEE and LCG projects at CERN. Hundreds of end-user physicists will run analysis jobs at the same time, processing large amounts of data (up to several hundreds TB) replicated over several tens GRID sites. Used in this way, GRID will become a highly dynamic, large-scale environment exhibiting chaotic access patterns. The primary difficulty with Interactive Data Processing Applications is the constrained response-time. Typical jobs in a batch mode may take hours or days to complete. The typical turnaround time for an effective interactive analysis should be few minutes at most (first feedback available for the researcher): in contrast with the batch model, the researcher should be provided a light procedure to interrupt the current analysis, change parameters and repeat the procedure on a very fast cycle. In addition, the data access patterns, physical data replication, meta-data catalog mappings are extremely complex. As today, the GRID middleware is primarily oriented towards batch job processing and even the simplest operations (such as job submission) may not have acceptable turnaround time. To cope with this complex environment special techniques based on customizable scheduling and resource allocation policies must be studied, which would exploit the intrinsic parallelism of the data analysis jobs. Greedy resource allocation policies, such as redundant execution of slowest tasks and pre-allocation of worker nodes, may improve the response-time but it may also reduce the overall processing capacity for other users. Optimization of job execution on a per-user basis must be harmonized with the performance of the entire GRID infrastructure and mapped correctly to local site policies. The integration of the parallel task execution model into the generic GRID middleware architecture must be studied. The CERN ARDA project (http://cern.ch/arda) offers a possibility to study, implement and optimize the interactive analysis prototype for the real-life analysis applications of LHC experiments. The work will be based on the experience gained during the implementation of a Distributed Analysis Prototype for one of the LHC Experiments: ALICE, ATLAS, CMS or LHCb. The actual experience and measurements should be reconciled with the modeling of the computing system which will be part of the research activity. At the same time the study will offer the possibility to generalize the experience and results to cover full range of HEP applications as well as applications in other scientific contexts such as biomedical and other sciences.
Special Requirements	Linux, Web Services, C++, Python, Perl
Training Value	The trainee will gain valuable experience in Grid technology and distributed computing with strong emphasis on HEP application.
