Using  the Transport Layer Security (TLS), Intel AMT supports the encryption of communications between the management console and clients.  Enabling TLS communications requires the creation of Intel AMT security certificates.  While developers may not be aware of this process, it is a straightforward process. 

Gael Hofemeier and Matt Gillespie have written a very thorough guide that gives developers the background and step-by-step procedures to create Intel AMT security certificates.   Read their guide to discover the step-by-step process.

Yet, there are some key differences you have to consider when using Intel Active Management Technology features on a virtualized client.  Whether you are an IT manager or even, a software consultant working with a major business client, it is important to know the differences and any other Best Known Methods to allow adjustments to the IT processes for managing virtualized clients with Intel Active Management Technology.  A recent white paper on the vPro Developer Community website describes the expected behavior and these Best Known Methods for IT managers.  Read the white paper to learn more.

This is an area that continues to gain attention by IT managers and software developers that are trying to address the needs of efficiently managing PC's, addressing malware/viruses and the security of data on PC's.  Intel has been addressing these concerns for some years with its Intel vPro technology that has been built into various Intel processor-based desktops and laptops.  So, if you are a software developer of IT manageability and security software and you want to learn more about vPro technology and how to enable your software to take advantage of it, recently a new community has been launched to provide you with the information that you may want.  This is the Intel vPro Developer Community.  Check out this new community and discover more about Intel vPro technology.

"Tips and Tricks for Kernel Development".  I don't know how I missed this article before, but with all the recent interest in OpenCL, I thought this would be a great article for programmers to review if they are doing kernel development within OpenCL.  This article has great advice for the programmer that is working on kernel development.  Starting with info on "Why optimizing kernel code is important" to "Avoiding Handling Edge Conditions in Kernels" to "Avoid Extracting Vector Components", there are "Tips and Tricks" that I think will come in handy for those programmers focusing on kernel development.  Read the article  "Tips and Tricks for Kernal Development".

On March 21,  Alex Wells (Intel) posted the Kernel Template Library to the article page of the Parallel Programming Community. This library set of headers defines a methodology for defining High Level helper objects for using them to express the algorithm of a Kernel.  Alex explains breifly how this kernal template library can then apply that kernel to each element of its data streams in a data parallel manner.  Alex explains more in his article and has posted the Kernal Template Library for developers to download.  Check this out yourself and download the Kernal Template Library for your own use.

Intel AVX significantly increases the floating-point performance density with improved power efficiency over previous 128-bit SIMD instruction set extensions.

Recently, I found an interesting whitepaper, "Benefits of Intel AVX for Small Matrices",  written by Pallavi Mehrotra and Richard Hubbard that examines how some of the Intel AVX architecture features such as wider 256-bit registers, new data manipulation and arithmetic primitives can benefit operations on matrices of small sizes. Their whitepaper examines simple operations such as matrix addition and multiplication, as well as more complex ones like computing the determinant of a matrix. Read their whitepaper to get the full details.

Stan's article, "3D Vector Normalization Using 256-Bit Intel Advanced Vector Extensions (Intel AVX)" outlines how developers can improve the performance of geometry computations by transposing packed 3D data on-the-fly to take advantage of 8-wide SIMD processing.  Stan details how to exploit 256-bit Intel AVX to normalize an array of 3D vectors.  In his article, he describes a shuffle approach to convert between AOS and SOA on-the-fly in order to make data ready for up to 8-wide single instruction multiple data (SIMD) processing.  Read Stan Melax article to get the details of this use of Intel AVX.

You may need to get a parallel program to sync both lifetime of- and access to- an object in shared memory.

Known methods suffer from either limitation of scalability or additional synchronization overhead.  Anton Malakhov has written a detailed blog that examines this situation and presents a new synchronization algorithm for shared dynamic objects.  Read Anton's blog and share with us what you think of this new synchronization algorithm.

Think of such examples as the cache-blocking factors in matrix computations, the task granularity in Threading Building Blocks, and the scheduling policy of OpenMP parallel constructs. The output is a tuned version of the program based on the searching results. This tool is easy to use with no compiler dependency.  You can learn more and download the Intel Software Autotuning Tool on Intel's Parallel Programming Community.  Check it out and let us know how it performs for you.

He takes this algorithm and showcases the common method for parallelizing this algorithm and then he outlines several different approaches  to parallelizing this algorithm.  The final method produces a fully cache sensitized approach to parallelizing this algorithm.  Jim's article is very detailed with some great code examples that I think you will find very useful.  He has gotten some good reviews by developers that have read this article.  I'd like to recommend reading this multi-part article.

Let me know what you think of Jim's article, Superscalar Programming 101 (Matrix Multiply).
