The 7th International Workshop on Feedback Computing San Jose, California, USA September 17, 2012 Feedback Computing 2012

Group Discussion Feedback Computing 2012

Research (Seed Topics) –New scope Broader perspective on feedback in computing systems More complex computing systems Feedback based design patterns and integrated applications –Growing community Multiple disciplines: Automatic control, machine learning, mathematical optimization, cyber-physical systems, autonomic computing –Name change vs. paper change –White paper: main problem, things not addressed before, research agenda –Book: how many parts, how many chapters Feedback Computing 2012

Research (Discussion Summary) –Growing community (Yixin Diao) 2012 workshop participant profile: Automatic control (8), machine learning (2), mathematical optimization (1), cyber-physical systems (0), autonomic computing (10), N/A (7) –Paper scope Increase the role of learning, grow the scope (as large as autonomic computing or not), make deeper the goal for broadening (Jeffrey Kephart, Yixin Diao) Focus on feedback, dealing with the dynamics of the systems (Sharad Signhal) –Cloud computing A very important area to link with and have impact (Evangelia Kalyvianaki,..) –Consumability Design patterns, open source package (as in machine learning), … (Jeff, …) –Topics Performance such as response time and throughput is important, but not necessarily the pain points of the computing systems. Would be nice to address the problems such as availability and reliability. (Zhikui, …) Feedback Computing 2012

Education (Seed Topics) –Testbed –Curriculum (class module, seminar, tutorial) –Interdisciplinary –Internship Feedback Computing 2012

Education (Discussion Summary) –Testbed Have a target problem that is challenging and interesting enough for the different research teams who can work on the same problems and share the solutions on the workshop (Martina) The challenge is to have a large scale testbed system that can be shared by the community, for which we may leverage similar work done in other domains. Tarek is working on similar thoughts, not one but a small set of testbed/problems to address the diversity of applications, … (Martina, Jeff, Zhikui, Xiaoyun, Anders, …) Even a simulator that represent the typical dynamics of the large scale systems for the community can help but challenging too. (Zhikui, Sharad) Open Cirrus is one Open Cloud Computing Research Testbed that can be leveraged. See the link (Dejan) Feedback Computing 2012

Education (Discussion Summary) –Curriculum Language gap exists between different communities; not easy to push control related courses to the computer science/engineering students; can be part of the curriculum building effort in the cyber-physical system community; module to be embedded, special topic series, online courses (Mike, Bonnie, Ming, Chris, Ole…) An archive for the related references in feedback computing can be a good resource for the interested parties. (Martina, Xiaoyun) –Workshop Proceedings: Put it in the digital library to increase impact, … (Dejan, …) Reaching out message: emphasize the aspect of model-based, … (Sherif,...) Feedback Computing 2012

Collaboration (Seed Topics) –Workshop: why submit, why participate, move around –Social network: LinkedIn –Encourage research/funding –Joint proposal –Joint papers Feedback Computing 2012

Collaboration (Discussion Summary) –Impact of workshop locations 2012 workshop participant poll: come to the workshop because of the workshop (8), come to the workshop because of the conference (8), N/A (12) –LinkedIn A large set of members, need active members and more discussion messages, … (Xiaoyun, …) –Blog Create a community blog to contain interesting and relevant topics (Martina) –Funding Collaboration among different universities and between academia and industry (Yixin, …) Feedback Computing 2012
