16th International Workshop

on High Performance Transaction Systems (HPTS)

September 27-30, 2015

Asilomar Conference Grounds

Pacific Grove, CA

Every two years, HPTS brings together a lively and opinionated group of participants to discuss and debate the pressing topics that affect today's systems and their design and implementation, especially where scalability is concerned. The workshop includes position paper presentations, panels, moderated discussions, and significant time for casual interaction. The only publications are slide decks by presenters who choose to post them.

Since its inception in 1985, HPTS has always been about large-scale systems --- systems that extend the state-of-the-art. Over the years the focus has expanded from scalable transaction processing to very large databases to cloud computing. Today, scalability is also about big data --- capturing it, storing it, and analyzing it. Here are some of the questions we hope 2015 participants will address:

• What are today's most challenging workloads and how is technology changing to handle them?
• What interesting but out-of-the-spotlight large-scale applications are challenging current technologies?
• What new applications will be driving system requirements in the next five years?
• What are the biggest technology problems faced by large enterprises, and how are those enterprises addressing them?
• What is being done to reduce the skill level and level-of-effort required to develop, test, deploy, evolve and manage large-scale applications?
• What challenges arise from supporting applications that span multiple software systems and datacenters?
• What effect do multi-tenancy, containerization, and the proliferation of micro-services have on infrastructure to support large-scale applications?
• How are networking, storage and computing changing to support large-scale applications?
• How are application design and administration affected by the range of available storage and interconnect technologies?
• What new software technologies are being developed to support large-scale applications, and what new apps do those technologies enable?
• How is heterogeneity of software, databases, and infrastructure affecting the implementation of large-scale applications?
• What are systems doing to ensure security and privacy, and to avoid abuse and fraud?
• How do large-scale systems handle, fault injection, failure management, and recovery from byzantine outages?
• What system challenges are arising from large-scale data analytics and machine learning?
• What is the relative importance of throughput, response time, capacity, and availability when designing large-scale systems for different application domains?
• How are systems implemented, configured, and managed to meet a range of response-time SLOs (from real-time to batch) and data lifetimes (from current state to archival)?

Others topics are welcome, as long as they are likely to be of interest to people building large-scale systems.

If you would like to attend, please submit a one-page technical position paper that presents a viewpoint on a controversial topic, a summary of lessons learned, experience with a large or unusual system, an innovative mechanism, an enormous problem looming on the horizon, or anything else that convinces the program committee that you have something interesting to say to builders of large-scale systems. The submission process is very lightweight, in part to attract systems developers who can't set aside time to write a paper. Each submission can have many authors. However, if the submission is accepted, only the corresponding author will receive an invitation to attend. At most one submission per corresponding author, please.

The workshop is by invitation only and will have under 100 participants. The submissions drive both the invitation process and the workshop agenda. Participants may be asked to give a presentation at the workshop. Students are particularly encouraged to submit and will enjoy a discounted workshop fee.

What to submit:

• A one-page position statement in .pdf, in 10pt font or larger.
• Optionally, a short summary of the corresponding author's current work, such as a link to the author's homepage or Linked-In page, or a short bio added to the position statement (beyond the one page).
• Optionally, a link to one or both of the following:
• Maximum of 3 PowerPoint-type slides, augmenting your position statement.
• Maximum 2-minute video illustrating your position statement, such as a demo or a presentation of you speaking (with or without slides).

The length limits will be strictly enforced. We won't consider submissions that exceed the maximum length.

The workshop begins with dinner on Sunday, September 27 and ends with lunch on Wednesday, September 30.
