Abstract (English)

The complexity of today's engineering simulations demands the use of many HPCN and engineering simulation tools by end-users. All of these tools need to be accessible to the engineer and, ideally, in a seamless environment. Simultaneously, issues such as 'time to market' demand significant reductions in design time as product complexity increases. Consequently the end-user engineer has an extremely complex simulation system to control, both the hardware and the software, and the human productivity needs to increase to achieve order of magnitude reductions in design time for many applications.Increased performance at reduced cost of HPCN platforms enables the required growth in simulation across many industrial sectors to help addressing the above issues. However, the full benefit of such HPCN systems can only be realised if greater efficiency is introduced into the end-user interfaces for the whole simulation process. The multitude of tools needed for a single complex simulation brings a number of bottlenecks and limitations associated with the tools, how well they work together and transferring data between them. These bottlenecks have been prioritised and addressed in this project in order to develop an integrated functional HPCN environment for multi-disciplinary simulations, to provide and demonstrate HPCN tools and engineering simulation tools that will efficiently work together in this environment, and to put developments in place to remove the main limitations and bottlenecks in engineering simulation.The entire system working with embedded applications software for real industrial problems including multi-site co-operative working was demonstrated by means of an industrial test case suite, agreed to by the industrial end-users. The test case suite was used to steer the technical developments and enable the end-user industries to evaluate the developments and to provide feedback to the developers throughout the project.SMR has contributed to the Julius project in two different realms simultaneously (1) Data management of HPC simulations and (2) CAD-mesh interfacing of large FEM-based simulations. The HPC data management system MemCom and associated tools, like data browsers and 3D viewing tools, were integrated in the Julius environment. A parallel data access library based on the SPMD (Single Program Multiple Data) programming model was developed and implemented by SMR. In addition, a CORBA based client-server version of the MemCom data manager was implemented and demonstrated within the object factory environment of the Julius project. Import/export filters for reading and writing proprietary mesh file formats as well as for reading HAEDB (Hypersonic Aerothermal European Database) computational CFD data were developed and demonstrated.
