  1. The Future Of Research Clouds Dan Reed Scalable and Multicore Computing Strategist Managing Director, Data Center Futures Microsoft Corporation

  2. Sapir–Whorf: Context And Research • Sapir–Whorf Hypothesis (SWH) • Language influences the habitual thought of its speakers • Scientific computing analog • Available systems shape research agendas • Consider some past examples • VAX 11/780 and UNIX • Workstations and Ethernet • PCs and web • Inexpensive clusters and web services • Today’s examples • Multicore, sensors, clouds and services …

  3. Today’s Truisms (2008) • Bulk computing is almost free • …but software and power are not • Inexpensive sensors are ubiquitous • …but data fusion remains difficult • Moving lots of data is {still} hard • …we’re missing trans-terabit/second networks • People are really expensive! • …and robust software remains labor intensive • Scientific challenges are complex • …and social engineering is not our forte

  4. The Transductive Continuum • Dynamic adaptation • Computing, data and bandwidth • Deep integration and software services • Edge devices and large centers • Context-aware information • The right information at the right time • The cloud follows you everywhere • Business, home, play …

  5. Economics Drive Change • Moore’s “Law” favored consumer commodities • Economics drove enormous improvements • Specialized processors and mainframes faltered • The commodity software industry was born • Implications • Consumer product space defines outcomes • Follow the money • Clouds are a consequence of commodity exponentials • Inexpensive storage, broadband networks and multicore processors Source: Jim Larus

  9. Embarrassingly Parallel Processing • When applications are hosted • Even sequential ones are embarrassingly parallel • Few dependencies among users • Moore’s benefits accrue to platform owner • 2x processors → • ½ servers (+ ½ power, space, cooling …) • Or 2x service at the same cost • Tradeoffs not entirely one-sided due to • latency, bandwidth, privacy, off-line considerations • capital investment, security, programming problems Source: Jim Larus

  16. The Data Explosion Simulations Archives Literature Experiments From petabytes to Exabytes

  17. Data and Information What information consumes is rather obvious: it consumes the attention of its recipients. Hence a wealth of information creates a poverty of attention, and a need to allocate that attention efficiently among the overabundance of information sources that might consume it. ~Herbert Simon

  18. Data Distribution Data Convergence Our Data Models Are In Rapid Flux Irregular Local Analysis Research Questions Limited Data Internet Traditional Databases Regular Fusion Unstructured Structured Many Petabytes Distributed Analysis

  34. Memex: Still Prescient “Consider a future device for individual use, which is a sort of mechanized private file and library. It needs a name, and to coin one at random, “memex” will do. A memex is a device in which an individual stores all his books, records, and communications, and which is mechanized so that it may be consulted with exceeding speed and flexibility. It is an enlarged intimate supplement to his memory.” ~Vannevar Bush “As We May Think,” Atlantic Monthly, 1945

  35. Research In The Cloud Visualization and analysis services Scholarly communications A Future Research Environmentwith both Software + Services Domain-specific services Searchbooks & citations Blogs & social networking Instant messaging Reference management Identity Mail Projectmanagement Notification Document store Storage/data services Knowledge management The Microsoft Technical Computing mission to reduce time to scientific insights is exemplified by the June 13, 2007 release of a set of four free software tools designed to advance AIDS vaccine research. The code for the tools is available now via CodePlex, an online portal created by Microsoft in 2006 to foster collaborative software development projects and host shared source code. Microsoft researchers hope that the tools will help the worldwide scientific community take new strides toward an AIDS vaccine. See more.

  36. Academic Research Implications • Consider integrated, holistic designs • Integrative and reductionist approaches • Consider data centers and clouds • Take the long term view • Ten years horizons and new applications • Think about appropriate scales • Much larger than normally considered • Investigate the hard problems • Technically and politically

  37. Microsoft, Academia and Clouds • What would make a difference? • Software access • Hosted services • Hosted data • Hardware and software • We want to hear from you

  38. The Cambrian Explosion • Most phyla appear • Sponges, archaeocyathids, brachiopods • Trilobites, primitive mollusks, echinoderms • Indeed, most appeared quickly! • Tommotian and Atdbanian • … as little as five million years • Lessons for computing writ large • It doesn’t take long when conditions are right • raw materials and environment • Leave fossil records if you want to be remembered!
