Intel Threading Building Blocks

In addition to the Black Belt, Brown Belt and Green Belt Software Developer titles, I am going be updating the Hall of Fame Page periodically with the objective of recognizing members of our communities who go above and beyond, help other members and ... [More] strengthen our communities through their high-quality contributions. Browse through the recently updated [...] [Less]

We have often stated the three main points of parallelism are: Correctness, Scalability, and Maintainability.    We are working to provide better tools to improve all three aspects of software development.  The other month I wrote about Intel ... [More] Threading Building Blocks which helps provide an abstraction that helps with both maintainability and scalability.    I wonder how [...] [Less]

The ever-expanding Intel Architecture instruction set offers performance improvements for a wide number of application segments.  With that comes the need to ‘code path’ – i.e. run the particular code that utilizes the full potential of the ... [More] particular processor its running on.  Of course, there are practical limits on the number of code paths supported [...] [Less]

I thought my tools were in order to dig inside the TBB task scheduler, but rethought the approach to come up with a new and improved way to look at my nested parallel_for concurrency by seeing how task stealing partitions the work

In discussing the ins and outs of parallel programming, we need to distinguish between the terms processor, processor core and hardware threads. It is easy to be imprecise and say 'processors' sometimes when we mean 'processor cores' - but with ... [More] multicore processors being everywhere it seems that more and more we are getting used to talking about processors [...] [Less]

Here at Microsoft's Professional Developers Conference, I'm busy attending every session they have on parallelism.  Microsoft engineers deserve high marks for talking about parallelism at PDC very well - not hyping it, not ducking it - very good presentations.  I suspect much of it will end up on Channel 9 and will be worth watching [...]

In my previous post I've tried to explain why TBB containers are so different from the STL ones, and claimed “efficiency” and “performance” considerations to be important reasons. For the starter let me to clarify what exactly did I mean when I talked about them. The meaning of performance in general is intuitively obvious - the [...]

How TBB concurrent containers differ from the STL ones, why the particular design decisions were made, and what the efficiency of both approaches depends on...

A number of new features and improvements went live on Intel Software Network last week. My personal favorite is how easy it is going to be from now on to contribute & share articles, videos and blogs. One of the new features is also a ranking system and community recognition. While the Intel Black Belt Software [...]

In my first blog that I said I would blog mostly about threading and performance.    This time I am writing about TBB or Intel® Threading Building Blocks.  But let me begin by discussing the multi-core transition.   Several years ago Intel began shifting to multi-core platforms.   This was a shift for Intel (you may remember we [...]
