Common use of MPI Clause in Contracts

MPI. Support for parallel computing (MPI) applications are critical for many user communities but the integration of this capability into the general infrastructure has been difficult. This task will focus on the improvement of the core services and software needed to support MPI, while engaging with two representative user communities (CCMST & Fusion) to ensure that the offered support meets their requirements. TSA3.3: Services for High Energy Physics (HEP) The HEP VO specific services are devoted to the support of the Grid interfaces of the 4 LHC experiments and are of particular importance now as we enter the exploitation phase of the world’s largest scientific machine – the Large Hadron Collider at CERN. They will ensure the LHC experiments can rely on the Grid for their data handling, as planned in the LCG Technical Design Report . All LHC VOs require optimizations and improvements in a number of common areas: workload management, data management, monitoring, service deployment and operation. These optimisations – of which specific details are provided in the task description below – are an essential part of the move to sustainable operations, as well as handling additional load and complexity expecting from LHC data acquisition, (re-)processing and analysis. An agile structure will be used to organise this work allowing the team to react quickly to high-priority needs of the LHC VOs as experience of the accelerator grows.
