    29. 31. Nov 17 - 19 PDC09 LA CC <ul><li>Manycore and the Microsoft .NET Framework 4: A Match Made in Microsoft Visual Studio 2010 </li></ul><ul><li>Stephen Toub </li></ul><ul><li>The Microsoft .NET Framework 4 and Visual Studio 2010 include new technologies for expressing, debugging, and tuning parallelism in managed applications. Dive into key areas of support, including the new System.Threading.Tasks and System.Collections.Concurrent namespaces, cutting-edge concurrency views in the Visual Studio profiler, and debugger tool windows for analyzing the state of concurrent code. </li></ul>
    30. 32. <ul><li>Effective Concurrency: Design for Manycore Systems </li></ul><ul><li>August 11 , 2009 by Herb Sutter </li></ul><ul><li>Why worry about “manycore” today ? </li></ul><ul><li>… building a typical mainstream application right now? …, &quot;many-core&quot; systems still feel fairly remote, not an immediate issue to think about as developers are working on their current product. </li></ul><ul><li>… why it’s time right now for most of us to think about systems with lots of cores. </li></ul><ul><li>In short: Software is the (only) gating factor ; as that gate falls, hardware parallelism is coming more and sooner than many people yet believe. … </li></ul>
    31. 33. The Problem with Threads, Edward A. Lee Intel, for example, has embarked on an active campaign to get leading computer science academic programs to put more emphasis on multi-threaded programming. If they are successful , and the next generation of programmers makes more intensive use of multithreading, then the next generation of computers will become nearly un usable .   EECS Department, University of California, Berkeley Technical Report No. UCB/EECS-2006-1, January 10, 2006 http://www.eecs.berkeley.edu/Pubs/TechRpts/2006/EECS-2006-1.pdf Threads are a seemingly straightforward adaptation of the dominant sequential model of computation to concurrent systems. Languages require little or no syntactic changes to support threads, and operating systems and architectures have evolved to efficiently support them.
    32. 34. F# Async/Parallel
    33. 35. In Praise of Immutability <ul><li>Immutable objects can be relied upon </li></ul><ul><li>Immutable objects can transfer between threads </li></ul><ul><li>Immutable objects can be aliased safely </li></ul><ul><li>Immutable objects lead to (different) optimization opportunities </li></ul>
    34. 36. The Solution <ul><li>Good Architecture </li></ul><ul><ul><li>Know your techniques </li></ul></ul><ul><ul><li>Know your requirements </li></ul></ul><ul><ul><li>Know your limits (CPU, disk, network, latency) </li></ul></ul><ul><li>Translate Good Architecture into Good Code with F# </li></ul><ul><ul><li>A great platform </li></ul></ul><ul><ul><li>A massive increase in isolation and immutability </li></ul></ul><ul><ul><li>A massive reduction in mutation </li></ul></ul>In parallel programming, F# is a power tool for good architects and good developers

    37. 39. Luca Bolognese’s Blog <ul><li>All functional languages are enjoying a renaissance of sort (Erlang anyone?). </li></ul><ul><li>A strong reason is the multicore revolution that is upon us. </li></ul><ul><li>Functional languages, with their lack of side effects, are good for parallelization . </li></ul><ul><li>Also, with LINQ we brought functional concepts in a mainstream programming language. We made them a bit more familiar to people. </li></ul><ul><li>When you put all these things together you get a lollapalooza effect. </li></ul><ul><li>Sunday, November 09, 2008 9:33 AM by lucabol </li></ul>

    39. 41. Why inventing another language? <ul><li>Programs today are hard to parallelize </li></ul><ul><ul><li>Using threads leads to nondeterministic behavior </li></ul></ul><ul><li>Some ideas are difficult to express </li></ul><ul><ul><li>Declarative programming is easier to understand </li></ul></ul><ul><li>In OOP you can easily write reusable type </li></ul><ul><ul><li>But writing reusable function/algorithm isn’t that simple </li></ul></ul><ul><li>Sometimes you need to target multiple “runtimes” </li></ul><ul><ul><li>For example CLR, SQL and JavaScript hosted in browser </li></ul></ul><ul><ul><li>In F# it is possible to “compile” F# code to other languages </li></ul></ul>

Future computational semasiographic technology has the possibility of initiating a revolution in the development of semasiographic writing systems by making it far easier to write semasiographic motion pictures. </li></ul><ul><ul><li>see ref. : http://slcreativity.org/wiki/index.php?title=Garage_cinema_and_the_future_media_technology_by_Marc_Davis </li></ul></ul>SEMASIOGRAPHIC
    58. 61. <ul><li>The first two levels of Geoffrey Sampson’s taxonomy of writing systems divides writing systems into semasiographic which represents “ meanings ” (from the Greek semasi “meaning”), and glottographic which represents “sounds” (from the Greek glotto “tongue” or “language”). </li></ul>

How can we use its ability to record and construct events in the world in a way analogous to how computational writing captures processes as objects and uses them to build new processes? </li></ul><ul><li>As with the invention of writing (or even language) itself, the deep integration of motion pictures and computation will bring about entirely new possibilities for human expression and communication. </li></ul>
    65. 68. <ul><li>ALTHOUGH WE ARE LIVING IN THE “COMPUTER AGE,” THE FULL IMPLICATIONS of computational ideas have not been realized in our century. We are at the early apparatus phase of computational development—the profound ideas of computation have not yet affected all other fields of human inquiry, especially our thinking about media . As computational ideas transform our thinking about media, new apparatuses and new ideas will emerge that will change our relationships to media and to each other. The ways we create, communicate, and play will become computationally revisioned, transforming us in the process. </li></ul>
