Acknowledgements: Special thanks to Ajith Illendula and Sudeepti Balepur for sending this guide to me in order to share with our vPro Developers Community. Objectives: 1. Create certificates for Intel AMT TLS encryption using the Intel AMT SDK and OpenSSL 2. Using the TLS.ps1 script, configure non TLS configured Intel AMT systems to use TLS communication [...] Read more
Nearly 11 years ago (!) I wrote an item for the Visual Fortran Newsletter on explicit interfaces in Fortran. In recent weeks, I have had to refer quite a few customers to this article, suggesting that many Fortran programmers don’t understand the role and rules of explicit interfaces. However, when I reread the item, I [...] Read more
In some of my earlier posts I’ve discussed new features in the Fortran language that might be unfamiliar to some. But this time I’m going to go the other way and describe some really old language features – so old that many newer Fortran programmers are mystified when they see them – but these features [...] Read more

The dust of SC’11 starts to settle and several announcements around OpenMP have been made in Seattle. There has been a change in the OpenMP Architecture Review Board and Language Committee. Several new members have joined the committee and started to actively participate in the development of future OpenMP versions. Also, Michael Wong (IBM) has [...] Read more
I ran into Mike Dewar at SC11 today as the exhibition draws to a close. Mike is the CTO of NAG Ltd. – a company we’ve had the good fortune to work with for years. NAG is one of a handful of companies that have been providing feedback on our Knights Ferry (prototype MIC architecture). [...] Read more
I’ve known this day was coming – but when I saw Knights Corner clearly sustaining a TeraFlop (DGEMM, wide range of block sizes) – I was surprised by my emotional reaction inside. Hard to describe; it was a good feeling. Tuesday November 15, 2011, we showed a Knights Corner co-processor for the first time outside [...] Read more
Open Parallel is a research and development company that focuses on parallel programming and multicore development. We are a bunch of highly skilled geeks from various backgrounds that work together on problems in parallel programming and software development for multicore and manycore platforms. At LinuxConf (LCA2010) James Reinders gave a talk about the Threading Building [...] Read more
Intel® Inspector XE is often recommended as a great tool for verifying the correctness and security of C++ applications, but it is important to note that this tool works just as well on Fortran and C# programs. If you develop in one of these languages, Intel Inspector XE can be a very valuable tool in [...] Read more
Program analysis tools can be valuable for debugging program correctness and performance issues, even more so for multi-threaded programs. Some of these tools need to know about certain events in the program. For example, race detection for Intel® Cilk™ Plus programs requires knowing precisely when spawn and sync events happen. Similar events are necessary to analyze [...] Read more
While Moore’s Law continues to double transistor count every 18 months, the translation into performance of the Top 500 computers in the world is resulting in a much faster pace. Helping software development keep pace requires great tools. Read more

This is not to say that compilers can automatically parallelize code. I would however really like to see that happen and here is an interesting and reliable way to parallelize operations. If a compiler can use this method of thinking then it can also be used as hints for developers writing code today. C and [...] Read more
I have been using a program called Xfrog for more reasons than it has a great name. Many years ago I was told about it by several people, and one of them was Saty Raghavachary, a programmer and educator at DreamWorks Animation. I only regret it has taken me so many years to start using the [...] Read more

DreamWorks Animation seeks to thread complex rendering applications that were written before threading was commonplace. This article shows a technique to find and fix thread safety issues by executing legacy code in a threaded test harness and monitoring execution with Intel developer tools. Our engineering engagement with DreamWorks Animation involved introducing thread parallelism in performance [...] Read more
