Intel Threading Building Blocks (also known as TBB) is an open-source portable C++ template library for writing software programs that take advantage of multi-core processors.

From Wikipedia:

Intel Threading Building Blocks (also known as TBB) is a C++ template library developed by Intel Corporation for writing software programs that take advantage of multi-core processors. The library consists of data structures and algorithms that allow a programmer to avoid some complications arising from the use of native threading packages such as POSIX threads, Windows threads, or the portable Boost Threads in which individual threads of execution are created, synchronized, and terminated manually.

Instead the library abstracts access to the multiple processors by allowing the operations to be treated as "tasks", which are allocated to individual cores dynamically.

Multithreading in LLVM

I need to generate LLVM code that will serve a lot of threads/tasks (hundreds of thousands). These threads should be lightweight like Intel TBB's tasks, golang gorutines or other. Of course they can be implemented with external C++ libraries like…

Using C++11 thread_local with other parallel libraries

I have a simple question, can C++11 thread_local be used with other parallel models. For example, can I use it within a function while using OpenMP or Intel TBB to parallel the tasks. Most such parallel programming models hide hardware threads…

Homegrown workqueue vs Intel TBB

We are considering which parallel framework for C/C++ to use. We have some very special conditions and are not 100% sure, that e.g. TBB can add something "more". There are N running threads and one synchronized workqueue (using pthread mutex). Our…
