15th Cloud Control Workshop, June 11-13, 2019

Program and abstracts

The 15th Cloud Control Workshop, to be held at Sandhamn, Sweden, is a high-profile workshop targeting academic and industrial technology researchers and leaders from all around the world. Participation is by invitation only.

The workshop will be held just before The 16th IEEE International Conference on Autonomic Computing (ICAC 2019) and The 13th IEEE International Conference on Self-Adaptive and Self-Organizing Systems (SASO 2019), also being held in Sweden. As always, the aim of the 15th Cloud Control Workshop is to foster multidisciplinary research in cloud management, leveraging expertise in areas such as autonomic computing, control theory, distributed systems, energy management, machine learning, mathematical statistics, performance modeling, systems management, etc.

By providing an understanding of the research challenges ahead and by fostering multi-disciplinary research collaborations. The ambition is to shape the future of resource management for any type of resources important for the cloud, from single servers to mega-scale datecenters, including, e.g.,  mobile edge clouds, fog infrastructure, and disaggregated and software-definied infrastructures on any scale, from rack-scale to datacenter-scale. The workshop targets leading industrial and academic researchers from any scientific discipline with potential to contribute to this multidisciplinary topic.

The ambition
The ambition is to create the type of event where people come, not to publish and extend their CV:s, but to discuss and learn, and most importantly, to establish or strengthen connections to interesting people with varying backgrounds, but all highly relevant to solving our problems in cloud control. To facilitate this we, in addition to a very discussion-oriented program, host the event on a small, relaxing, and inspiring location, with many opportunities to interact during the three days of the workshop.

Workshop format
The workshop format will be to mainly focus on multi-disciplinary research discussions in parallel sessions but also include some keynotes and some short scientific presentations on planned, ongoing, or completed research. The 15th edition will strive for a strong focus on cloud management using the techniques listed above, rather than on cloud in general.

Measuring and Optimizing Tail latency
Interactive web services require careful engineering to optimize tail latencies (99th percentile or higher) or users abandon the service. Optimizing these systems is challenging because tail latency is hard to measure and because non-deterministic root causes span networking, software, and hardware. We describe Shim, a new tool and application profiling methodology, that reads out hardware and software signals at 1000 cycle granularities without instrumenting applications at 1% overheads, which is orders-of-magnitude more frequent than interrupt based sampling. We also describe Google’s kernel trace scheduling framework. These tools divide tail latency into long requests and non-deterministic events, inspiring different optimizations and challenges.

After technical questions, I will show how myths, such as the sole genius, are counter productive to science and innovation. In contrast, social science shows diverse teams achieve better outcomes in controlled and uncontrolled studies. I will put these results in the context of my personal research experiences. I challenge you to build diverse research teams and mentor the next generation, so that your team will produce more innovative work

Speaker Biography
Kathryn S. McKinley is a Senior Staff Research Scientist at Google (2017-present). She received her BA, MS, and PhD from Rice University. Her research interests span programming languages, compilers, runtime systems, operating systems, cloud systems, and architecture with a focus on performance, parallelism, and memory systems. She and her collaborators have produced software systems widely used in industry and academia: the DaCapo Java Benchmarks (31,800+ downloads), the TRIPS Compiler, the Hoard memory manager (used by OS X), the MMTk memory management toolkit, the Immix garbage collector (in Jikes RVM, Haxe, Rubinius, and Scala), incremental parallelism in Bing, and the SHIM profiler. Her research papers have garnered five historical impact awards and ten were recognized with best conference and best in area awards. She has graduated 22 PhD students. She and her husband have three sons. Dr. McKinley is an IEEE Fellow and ACM Fellow.

Workshop Details


The venue is located on an island, quite far out in the Stockholm archipelago.
We will get there by a 50 minutes bus ride from Arlanda airport to Vaxholm followed by a 1 hour boat ride to Sandhamn. This will be done using chartered buses and a chartered boat before the start and after the end of the workshop. (There are also public transport available on a different route but that takes a bit longer time.)

The important times for local transport are:

  • Bus leaves Arlanda Airport at 9.00 on June 11 (from Terminal 4’s bus stops). Gathering immediately outside the exit of Terminal 4 at 8.45.
  • Bus arrives Arlanda Airport (Terminal 4) no later than 16.30 on June 13.

Registration fee
The workshop registration fee covers not only participation but also hotel room for two nights from June 11 to June 13, all meals and coffees during the workshop, some drinks for dinners, as well as bus and boat transportation from Arlanda airport to the workshop venue and back.

  • Total workshop and hotel fee for 3 days and 2 nights in single room: 5500 SEK + tax (6538 SEK incl tax), incl. all meals, coffees, some dinner drinks, boat and bus transportation, etc.

To register please use the link provided in your invitation email. Since participation is by invitation only, the link for registration is provided only in your invitation email.
