Adaptive algorithms are an important technique to achieve portable high performance. They choose among solution methods and optimizations according to expected performance on a particular machine. Grid environments make the adaptation problem harder, because the optimal decision may change across runs and even during runtime. Therefore, the performance model used by an adaptive algorithm must be able to change decisions without high overhead. In this paper, we present work that is modifying previous research into rapid performance modeling to support adaptive grid applications through sampling and high granularity modeling. We also outline preliminary results that show the ability to predict differences in performance among algorithms in the same program.

In general, developing fast applications for Intel Architecture (IA) processors is not difficult. An understanding of the architecture and good development practices make the difference between a fast application and one that runs significantly slower than its full potential. Of course, applications developed for the 8086/8088, 80286, Intel386™ (DX or SX), and Intel486™ processors will execute on the Pentium ®, Pentium Pro and Pentium II processors without any modification or recompilation. However, the following code optimization techniques and architectural information will help you tune your application to its greatest potential.

Keynote Systems (Keynote) has been busy preparing for several fall launches covering mobile, voice over IP (VoIP), Web site and user experience test and measurement services. To add fuel to the already fast-paced momentum, the company just announced end of fiscal year 2007 revenues that were the strongest in the company’s history—a 22% jump from its respective 2006 results! The thread across all of Keynote’s announcements is its “loud and clear” support for measuring the responsiveness, reliability and customer experience of Web sites using Web 2.0 technologies from the end user perspective.

Under the term “Web 2.0” the Internet is currently going through a new growth phase where end users create content and communities are built for user interaction. One of these Web 2.0 services is Flickr, a photo-sharing platform that allows users to upload photos, tag, comment and add them to favourite lists and build a personal social network.

ResolveRT’s deconvolution provides powerful algorithms for improving the quality of microscopic images recorded by 3D widefield and confocal microscopes. Two different methods are supported, namely a so-called non-blind and a blind deconvolution method, both based on iterative maximum- likelihood image restoration. In the first case a measured or computed point spread function (PSF) is required. In the second case the PSF is estimated along with the data itself.

The capabilities of seven dynamic buffer overflow detection tools (Chaperon, Valgrind, CCured, CRED, Insure++, ProPolice and TinyCC) are evaluated in this paper. These tools employ different approaches to runtime buffer overflow detection and range from commercial products to opensource gcc-enhancements. A comprehensive testsuite was developed consisting of speci?cally-designed test cases and model programs containing real-world vulnerabilities.
