Doctor Fortran in "I Can C Clearly Now, Part I"

Spend any time in the comp.lang.fortran newsgroup, or other places where programming languages are discussed, and you’ll soon see a new “Which is better, Fortran or C?” thread show up. These never fail to produce heated comments from people who should know better. My answer is that neither is “better” – each has its strengths [...]

Deterministic Reduction: a new Community Preview Feature in Intel® Threading Building Blocks

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

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

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 [...]

Why you should use Procedural and OOP in every application

Almost everyone wants to do architecture and almost everyone wants to do the UI. It means that every programmer has an opinion about the architecture and infrastructures in use. When you export an API for your system you get more opinions and when your product is an infrastructure (ex. Microsoft) you have too many opinions about [...]

one presenter exclaimed “Time spent optimizing for MIC is time well spent because it optimizes your code for non-MIC processors at the same time.”

Serial Equivalence of Cilk Plus programs
By Robert Geva (Intel) (2 posts) on April 7, 2012 at 7:01 am
Comments (2)
The serial equivalence of a Cilk™ Plus parallel program There is a trend in the C++ community to grow capabilities thru more libraries and as much as possible, avoid adding language keywords. Consistent with these trends are Intel’s Threading Building Blocks and Microsoft’s Parallel Patterns Library. The question arises, then, why implement Intel’s Cilk™ Plus as [...]

Minimize frustration and maximize tuning effort with Amdahl's Law

I recently had a question from a customer who had introduced a succesful optimization to a hot function in his application, but did not see as much improvement in the overall application as he expected. This is a fairly common occurence in the iterative process of performance tuning. Usually it happens for one of two [...]

The Windows 8 Consumer Preview ISO image became public a few days ago, which is available here, so I am sure a lot of people are interested in trying it out on their development systems without replacing their current Windows 7 installation. If you've ever dual booted a system before, the procedure for doing it [...]

It is with the utmost pleasure, I'd like to call your attention to the Dr. David Valentine's "Making Parallleism Nifty" video series. Dr. Valentine said at SIGCSE 2011 in Dallas that "good instructional materials begin with a brilliant, engaging assignment." Dr, Valentine received his grant in 2011 for his work applying an investigative model used [...]

Vectorization Series, Part 3 - What are the Benefits?

This will be the final post in my planned short vectorization series. Although I reserve the right to post more on vectorization in the future! In the first post on this topic, I explained that vectorization was parallelism inside a single CPU core, achieved by applying a CPU instruction to multiple data elements at once. [...]
