C++ Memory Model and Low-level Atomic Operations
This article and code examples are based on chapter 5 of C++ Concurrency in Action book by Anthony Williams. Chapter 4 is described here. You can download the code here. We will look at low-level details of the C++11 memory model and atomic operations that provide the basis for synchronization between threads through specializations of […]
C++ Events using Condition Variables
This code is from the chapter 4 of the C++ Concurrency in Action book by Anthony Williams and can be downloaded directly from the book companion site. I made some minor changes and compiled it in Visual Studio 2013. Making the code available on MSDN may help many who learn multithreading in C++. Code to chapter […]
Basic thread synchronization in C++
This code is from the chapter 3 of the C++ Concurrency in Action book by Anthony Williams and can be downloaded directly from the book companion site. I made some minor changes and compiled it in Visual Studio 2013. Making the code available on MSDN may help many who learn multithreading in C++. Solution has […]
Ripple Effect in Windows 8.1 Store Applications (C++/CLI)
The sample is a Windows 8.1 application demonstrating simple DirectX effect. This effect will produce a sinusoidal wave across a loaded image, like in a picture below. The code is from the patterns & practices DirectXRipple sample where I upgraded it to VS13, removed deprecated code, and cleaned it up a little. Here’s the solution […]
Histogram on GPU using CUDA
The following sample demonstrates how to compute a histogram on a GPU. CUDA SDK has a histogram sample which works for 64 and 256 bins with code both running on GPU and CPU. SDK CPU code is using bit-manipulation which should be replaced with SSE2 instructions. This article demonstrates 3 simple, entry-level, examples showing the […]
Matrix Transpose on GPU using CUDA
The following sample demonstrates matrix transpose on GPU. It starts with sequential code on the CPU and progresses towards more advanced optimizations, first a parallel transformation on the CPU, then several transformations on the GPU. In real life, it is impractical to do just a single matrix operation on the GPU due to the cost […]
Red-eye Removal with CUDA
This code demonstrates basic steps for red-eye correction in pictures. It requires a picture of someone with red eyes and a small template file which is a picture of a red eye to help us find eyes in the original picture. While the sample works with the picture that I tested it with, it requires […]
Sockets with Adaptive Communication Environment (ACE) Framework
Adaptive Communication Environment, or ACE for short, is a C++ framework to develop portable, high-performance networked multithreaded applications. References below introduce in greater detail to the history of the framework. ACE provides abstractions for sockets, demultiplexing loops, threads, synchronization primitives and can be used in high-performance, distributed real-time and embedded systems. ACE customers are Boeing and NASA, […]
Dining Philosophers in C++ 11
I have previously shown how to solve the problem using c#. I have to say that C++ 11 is officially awesome! Here’s my offering using that language. There are numerous solutions to the dining philosophers problem on the internet and I will not be reciting the story. You can find it at one of the following two […]
Dining Philosophers in C#
There are numerous solutions to the dining philosophers problem on the internet and I will not be reciting the story. You can find it at one of the following two links: MSDN Magazine Rosetta Code A few notes. Each philosopher is marked with a circle and can pick a chopstick on the left and on […]
