CEE Large-scale Engineering Projects

Large-scale Engineering Projects

Highly data intensive and computational demanding

Highly multidisciplinary, requiring the cooperation of different specialists

Involve large distributed teamsof researchers working together on a single complex problem

Each team of specialists has its own model of the engineering artifacts to be designed

Specialists have limited ability to understand each other's model

They proceed by successive refinement of the models.

LSEP example – Offshore Engineering

Integrated Visualization of production systems Sea Floor arrangement. Mooring and riser systems

Simulation of Structural Behaviors

LSEP Requirements

LSEP Requirements: Remote Collaboration Virtual Reality Visualization High Performance Computing (HPC)

LSEP main characteristics: Multidisciplinary, requiring cooperation of different specialists

organized in large distributed teams using distributed and heterogeneous resources;

Private partial models, with limited ability to understand each other’s model. Due to their huge complexity, LSEP are divided into smaller interrelated subprojects where each one have an equivalent representation of the others.

Data intensive & computational demanding;

LSEP Requirements

Virtual Reality Visualization and Remote Collaboration Understanding the output of large-scale computational science

runs is typically a group task, often with experts geographically distributed;

Analysis takes place over several days to weeks; Complex multi person problem solving strategies often are

required to understand and validate the simulation output. Data exploration through visualization provides new insights to

the users by comparing results from multiple simulations with distinct points of view in a 3D world.

HPC Large-scale computing work naturally fits into campaigns of

multiple weeks per problem with breathers in between

CPSE - Collaborative Problem Solving Environment

Problem Solving Environment (PSE) is a specialized software system that provides all the computational facilities needed to solve a target class of problems

Collaborative Problem Solving Environments (CPSE) focus on the development of a PSE coupled with collaborative environments to support the modeling and simulation of complex scientific and engineering problems

LSEP Requirements Remote Collaboration Massive Visualization High Performance Computing (HPC)

CEE Conclusion

38

From the offshore engineering viewpoint, the proposal of using a Scientific Workflow in their project life cycle

allows them to have a more structured way to solve their problems the idea of a CPSE conduces to the creation of engineering tools that

can be used by a wider group of users;

From the visualization viewpoint, the integration of a VRV and Remote Collaboration in the PSE

facilitates the information exchange and common understanding of complex problems. Users are compelled to think the overall solution of an engineering problem, using the visualization as a first class tool;

Contributions

39

From the CPSE viewpoint (cont.) Using an SOA architecture with an ESB and a MOM for dealing with

distributed applications and allowing then to cooperate using different technologies and with an asynchronous paradigm is also a valuable contribution for constructing a CEE;
