Background to the workshop
The International Exascale Software Project (IESP) recognised the importance of co-design vehicles within the exascale software design and development process .They noted that "Co-Design Vehicles (CDVs) are applications that provide targets for, and feedback to, the software research, design and development efforts in the IESP. Although the IESP has now concluded it is more important than ever that we continue to discuss, share and develop our joint knowledge around the exascale challenge. CDVs are required because there are several possible paths to exascale with many associated design choices along the way." One of the most successful examples of co-design is from Quantum Chromodynamics (QCD), with projects/systems such as QCDSP, QCDOC (with the resulting influence on IBM's BlueGene), APE and CP-PACS demonstrating this success. However the breadth of communities engaged in co-design activities has increased with the move towards exascale and now include communities such as fusion, computational fluid dynamics and climate. The workshop proposers are partners in the EC funded Collaborative Research into Exascale Systemware, Tools and Applications project (CRESTA), which focuses on the use of six applications with exascale potential and uses them as co-design vehicles to develop the appropriate underlying exascale software. The project has focused on developing a novel integrated co-design process, the co-design applications providing guidance and feedback to the exascale software development process and integrating and benefitting from this development.
By bringing together application scientists, software developers, hardware designers and numerical experts engaged in co-design, the workshop organisers wish to share research and practical experiences in this area and highlight best practice techniques.
Expected outcomes from the workshop
On completion of the workshop the organisers anticipate the following outcomes for the attendees from the international exascale community:
• A knowledge of the breadth of application area participating in co-design for exascale;
• An understanding of the challenges and benefits of the co-design approach;
• An overview of latest research and best practice in the implementation and execution of co-design.
In addition, the organisers anticipate that the workshop will increase the visibility and provide insight into the co-design process for the whole HPC community, not just those who can attend the workshop, mainly through the publication of the workshop proceedings.
