Summary
In this presentation from the JVM Languages Summit 2009, Cliff Click discusses the Von Neumann architecture, CISC vs RISC, the rise of multicore, Instruction-Level Parallelism (ILP), pipelining, out-of-order dispatch, static vs dynamic ILP, performance impact of cache misses, memory performance, memory vs CPU caching, examples of memory/CPU cache interaction, and tips for improving performance.

Bio
With more than twenty-five years experience developing compilers, Cliff serves as Azul Systems' Chief JVM Architect. Cliff joined Azul in 2002 from Sun Microsystems where he was the architect and lead developer of the HotSpot Server Compiler, a technology that has delivered dramatic improvements in Java performance since its inception.

About the conference
The 2009 JVM Language Summit is an open technical collaboration among language designers, compiler writers, tool builders, runtime engineers, and VM architects. The talks inform the audience, in detail, about the state of the art of language design and implementation on the JVM, and the present and future capabilities of the JVM itself.

    A Crash Course in Modern Hardware

    Like the presenter, I started programming in the days when you could calculate the execution time of your program by getting out the pocket-sized folding instruction set card and adding up the numbers of cycles for the instructions involved.

    Times have changed!

    This presentation is essential viewing for anyone who doesn't appreciate how much indirection there is between their program - even as machine instructions - and the runtime behaviour of mainstream processors.

    As usual, Cliff gives a great talk. I always learn new things, but end up feeling "there's so much more to learn".

    thanks

    Hi Sverre,

    Our video server appears to be down at the moment - our operations team is looking into it, and we'll get this back up and running ASAP.

    Thanks,

    do you have a transcript of the video ? Human are very effective at reading, you know ? Adding a transcript would spare a lot of bandwidth and is a lot more user and ecology friendly. It is also handicap friendly (for deaf people).

    This is a great talk. I haven't done any assembly programming for many years and have forgotten a lot of it. Interesting to hear the current state of play in terms of hardware.

    Your video link is unusable. Perhaps you are slashdotted. I would really like to see it!

    Very interesting topic - unfortunately, the video is choppy (bandwidth issues?) and fairly long. Wouldn't it be better to allow users to "skip to the next page" through the slides to see what the presentation is all about before investing 54 minutes on it? (e.g. slides a la slideshare.net, for instance). Once we get an overall picture of the presentation, sufficiently motivated users could then decide to invest their time on the choppy video.
    Right now I'm twiddling around with the video stream to see what the slides ahead are about ...
    This is a comment not on this specific video, but to the general usability (or lack thereof) of the video presentations.
