Learn about Intel thread building blocks open Source libraries
Brief introduction
We have found a powerful alternative to POSIX threads and windows-based threads, the Intel thread building block, which is a C + + based framework designed for parallel programming.

Win7opencv2.3.1vs2008: there is no error in compiling a small program in the Chinese version of opencv. when running the program, the error "Computer loss tbb_debug.dll" is reported ". The reason is that the dynamic library withtbb of opencv2.3.1 is used, but tbb is not installed in the system, so an error is reported. Sort out the collected solutions: 1. the simplest method:... opencvbuild

Intel TBB Open Source
Intel threading building blocks is a C ++ concurrent library mainly used for high-performance C ++ program development.
The main advantage is that it does not have compiler requirements like OpenMP and supports more concurrent models.
TBB is currently open-source under the GPL protocol and can be downloaded from the website to the source code and compiled
Add Intel TBB and Python support under Windows using VS2008 compilation OpenCV2.1Steps:1. Read the installguide:http://opencv.willowgarage.com/wiki/installguide on the OPENCV website carefully2. In the "2" Install prerequisite Libraries and Tools, it is mentioned that Python 2.6 or 2.7 is required if you want to support Python calls, and you also need numpy and scipy libraries. To upgrade Python to 2.7, refer to the article "Upgrading Python 2.5 to Py

The open-source TBB library developed by Intel cleverly utilizes the idea of pipeline, an Adaptive High-performance software pipeline TBB: pipeline is implemented.

In the last article (TBB: Pipeline, the power of the software pipeline), we finally raised several questions. Let's take a look at how TBB: Pipeline solves them one by one.
Why can pipeline ensure the sequence of Data Execution? Since TBB executes tasks through multiple threads in the final analysis, why is the string read after reading two strings first proces
TBB 2.2 provides a uniform header file: TBB. H. You can use all the TBB libraries as long as the file is included. You can use the following commands to create a static library for ease of use:

Who knows the performance and advantages and disadvantages of the program designed with OpenMP, Cuda, Mpi, and TBB. Please kindly advise me ~
I hope you can have a better understanding of this after learning it!
This problem is too big. It may not be clear to say three or two sentences.
Let's take a look at the parallel programming mode. There are shared memory and distributed, pure Data Parallel and task parall
Before we start the TBB journey, let's take a look at how to initialize and terminate the TBB library, after all, this is a basis for using TBB ~ ~ ~

Memory Allocation Problems
Memory distributor
Use a distributor in an STL container
Memory allocation is not only the basic task of programming, but also a major challenge affecting efficiency in multi-core programming. In C ++, we can use a custom memory distributor to replace std: allocator. Threading Building Blocks provides a Scalable Memory distributor compatible with std: allocator. Copyright 52bc.net
Each memory distributor has its own characteristics. The extens
