Deterministic Reduction: a new Community Preview Feature in Intel® Threading Building Blocks
By Alexei Katranov (Intel) (1 posts) on May 11, 2012 at 2:22 am

Computer Arithmetic has a lot of peculiarities [1]. One of these pitfalls is associativity failure in floating point arithmetic. For example, the two sums of fractions calculations below will not produce the same result when using floats: In a sequential program, it is not a big problem since the calculation order is exactly specified so [...]

Digital Logic Simulation with the Intel® TBB Flow Graph, Part 3: Putting together a simulation
By Terry Wilmarth (Intel) (10 posts) on May 5, 2012 at 9:00 am
Comments (0)
In Part 2 of this blog, I described a four-bit adder circuit built from components discussed in Part 1. In this last installment, I’ll continue using Intel®TBB’s flow graph to put together some signal input and output devices, and then use those to make a small simulation featuring the four-bit adder from Part 2. Let’s [...]

Digital Logic Simulation with the Intel® TBB Flow Graph, Part 2: Building bigger components
By Terry Wilmarth (Intel) (10 posts) on May 4, 2012 at 9:00 am

In Part 1, I described how to put together a basic logic gate using the Intel® Threading Building Blocks flow graph nodes or_node and multifunction_node. In this blog, I will assume the basic logic gates and_gate, or_gate and xor_gate exist, and use them to construct a four-bit adder. To begin with, I’ll first construct a [...]

In this multi-part blog, I’m going to show you how to put together a simple logic simulation program using the Intel® Threading Building Blocks flow graph feature. Please note that this example does NOT demonstrate a practical approach to digital logic simulation. The purpose of the example is to demonstrate the use of several types [...]

Aggregator: a new Community Preview Feature in Intel® Threading Building Blocks
By Terry Wilmarth (Intel) (10 posts) on May 2, 2012 at 9:00 am
Comments (0)
Intel® Threading Building Blocks (Intel® TBB) 4.0 Update 4 introduces a new Community Preview feature, the aggregator. An internal version of the aggregator has been in use in Intel® TBB for some time, appearing in the flow graph and concurrent priority queue implementations. An aggregator is like a mutex in that it enforces mutually exclusive [...]

Scalable Memory Pools: community preview feature
By Anton Malakhov (Intel) (6 posts) on December 19, 2011 at 5:05 am
Comments (3)
In TBB 4.0, we introduced new community preview feature (CPF) – the scalable memory pools. See the TBB Reference Manual (D.4) for formal and detailed description. In this blog, we will present them less formally and discuss what changes can be made. Motivation We had vague requests from customers to implement a memory pool (Wikipedia [...]

It's been a big year for us in the Intel Developer Products Division. We released Intel® Cluster Studio XE and Intel® Parallel Studio XE Service Pack 1. We continued to plan and design our products to provide support for the compute continuum. And of course we worked to grow our community of developers. Throughout the [...]

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 [...]

How to make a pipeline with an Intel® Threading Building Blocks flow graph
By Michael Voss (Intel) (10 posts) on September 14, 2011 at 8:20 am
Comments (0)
The Intel® Threading Building Blocks ( Intel® TBB ) flow graph is fully supported in Intel TBB 4.0. If you are unfamiliar with the flow graph, you can read an introduction here. A question was recently submitted about an implementation of a pipeline using a flow graph. That question made me realize that pointing out some of [...]

Using Intel® TBB 4.0 features to simplify Dining Philosophers
By Christopher Huson (Intel) (2 posts) on September 13, 2011 at 8:00 am
Comments (0)
Intel recently released the 4.0 version of Intel® Threading Building Blocks (Intel® TBB), in which most of the flow::graph Community Preview features from 3.0 have been made standard features, and some new nodes have been added as Community Preview features. The time has come to revisit the Dining Philosophers program. One of the new Community [...]

Using Buffering Nodes in Graphs in Intel® Threading Building Blocks
By Terry Wilmarth (Intel) (10 posts) on September 12, 2011 at 7:59 am
Comments (1)
When using the new flow graph in Intel® Threading Building Blocks (Intel® TBB), we often encounter a situation where a sending node is ready to output a data item, but no receiving nodes are ready to receive that data item. Sending nodes have differing semantics in this regard, but they often just throw data away [...]

Do you have a face for parallelism?

It's never nice to tell someone that they have "a face for radio." But, if you're going to be at IDF 2011, you should attend the "Faces of Parallelism" lab to show off your parallel face.
