10th IEEE International Scalable Computing Challenge (SCALE 2017)

Co-located with IEEE/ACM CCGrid, 2017.


The 10th IEEE International Scalable Computing Challenge (SCALE 2017) is sponsored by the IEEE Computer Society Technical Committee on Scalable Computing (TCSC). The objective of the SCALE Challenge is to highlight and showcase real-world problem solving using computing that scales. Effective solutions to many scientific and engineering problems require applications that can scale. There are different dimensions to application scalability. For example, applications can scale-up to a large number of cores on a compute unit, scale-out to utilize multiple distinct compute units, or exhibit elastic scaling to acquire and release resources on-demand, based on current need. The result may be an application that can solve a larger problem, increase throughput, and/or reduce execution time. In order to scale, applications need to be supported by tools, middleware, software cyber-infrastructure, programming frameworks, computing infrastructure, etc. The SCALE Challenge is concerned with advances in application development and their supporting infrastructure to enable scaling.

All papers presented at the SCALE challenge and selected by the Scale Challenge Committee of IEEE/ACM CCGrid 2017 will be submitted to IEEE Xplore for publication and EI indexing.


Competitors should submit proposals as white papers that outline the nature of the problem being solved, the solution technique, and document the scalability achieved. The technical committee will select finalists from these proposals, to present their work and demonstrate their system and/or software solution in action at the CCGrid 2017 conference. The judges will select a first prize winner at the conference. The white papers of the finalists will also appear in the proceedings of the CCGrid 2017 Conference.


The 10th IEEE International Scalable Computing Challenge (SCALE 2017) contest will focus on end-to-end problem solving using concepts, technologies and architectures (including Clusters, Grids and Clouds) that facilitate scaling. Participants in the challenge will be expected to identify significant current real-world problems where scalable computing techniques can be effectively used, and design, implement, evaluate and demonstrate solutions. Problems with social impact are of particular interest for the SCALE 2017 challenge. SCALE 2017 will be held in conjunction with the 17th CCGrid Conference in Madrid, Spain, May 14-17, 2017.

We invite teams to submit white papers outlining the problem addressed, and the technologies employed to enable the application to scale. Proposals may be up to 6 pages long in the standard IEEE paper format. In addition to listing team members and contact information, the proposals should clearly outline:

  • An overview of the problem being solved and the techniques employed
  • The application scenario and its requirements
  • Performance metrics (number of cores, computational throughput, I/O bandwidth, metadata operations, etc.), supporting data, and a qualitative description of how the application scales – scale-up, scale-out or any other type of scaling
  • The solution – architecture, underlying concepts and technologies used, highlighting the innovative aspects of the solution
  • Impact of the solution, including its extensibility, the uniqueness of the solutions and the results, and the extent to which the presented solution pushes the envelope in scalable computing
  • Analysis of the solution and technology employed with a comparison to related approaches

Papers will be shortlisted by a technical committee using the above criteria. Up to 5 papers will be invited to compete in a final round at CCGrid 2017. At least one member from each selected team must register, present and demonstrate their project at CCGrid 2017. Participation from students and early-career researchers, especially in leadership roles, is strongly encouraged.

Submissions of SCALE 2017 proposals should made through EasyChair selecting “Scale challenge”


The finalists will be judged on the quality of their presentation and demonstration, as well as their responses to questions by a technical committee, and a first prize awarded.
