Hello , I am not Linux and Unix expert so maybe this is a simple question to be answered , I am just not sure. I have a sever with 8 cores (running CENTOS) that executes a batch job once a day for few minutes . I tried to monitor the CPU usage foreach core when the batch is executed using the top command and then pressing '1'. There I saw something really strange (for me). Initially I saw that job being executed in Cpu5 (it was obvious because it is a job that needs almost 100% of the CPU …

I have read about how multicore processing works of the Intel. The manual that I read had left out a part that would of been useful how to actually use multiple cores. It just explained how all the different parts of the CPUs interact with each other, so could someone show me how to use them in assembly. If someone could give me some code in simplest form as possible (for me to understand), to help me that would be very helpful. The assembler I use is Nasm and I'm not to good at switching to protected mode so I …

[ATTACH=left]17191[/ATTACH]Today at Intel's IDF 2010 was the official launch of the 2011 version of Intel Parallel Studio. Parallel Studio is a set of tools that enhance Visual Studio to support full parallel programming. This is more than just a simple plug-in for Visual Studio. It's an entire set of tools covering the entire development workflow. In terms of parallel development, these steps are design, build and debug, verify, and tune. For designing, you have the Intel Parallel Advisor, which sismplifies the process of adding parallelism to your application. For the build and debug phase, you have the Parallel Composer. Together …

[ATTACH=RIGHT]17350[/ATTACH]Since the release of the second edition of Parallel Studio this month, I've spent a good amount of time with it, trying out the new features. First, what's Parallel Studio? It's an add-in for Microsoft Visual Studio that gives you a large set of features for writing parallel code that targets multiple processor cores. It includes a new C++ compiler that gets run instead of the built-in Visual C++ compiler, allowing you to take advantage of several new features. Parallel Studio integrates with all the recent versions of Visual Studio: 2005, 2008, and 2010. Parallel Studio 2011, which is the …

While most reporters and bloggers today are trumpeting the fine showing by chip-maker AMD in the semi-annual list of the world's [Top 500 Supercompting Sites](http://www.top500.org/list/2009/11/100), for me the real news is what AMD has planned for next year. In the first quarter of 2010, AMD is scheduled to begin shipping a processor that will include not only 12 cores, but also the vastly expanded memory bandwidth to support them. Code-named Magny-Cours, the processors will offer four channels for DDR3 memory, twice that of its 6-core Opteron top-performer, which by the way powers what is today considered [the fastest supercomputer in …

Thought you were bleeding edge with your quad-core PC? Think again. A company called Tilera today announced that it's working on a chip containing 100 processor cores, which it says could be seen by 2011. It's part of its new TILE-Gx line of 64-bit multi-core processors, the first of which--a 36-core chip--will be sampling by the end of 2010, the company said today in a [url=http://www.tilera.com/news_&_events/press_release_091026.php]statement[/url]. With its top-end TILE-Gx100, Tilera claims to outstrip Intel's next-generation Westmere processor in performance-per-watt by a factor of 10. Other models will contain 16 and 64 cores, and will sample in early 2011. But …
