Intel announced today that they're open-sourcing their cross-platform Thread Building Blocks 2.0 (TBB) template library. While the company contributes code to open-source project like the Linux kernel and drivers, the opening of TBB marks the first time that Intel has taken a commercial tool and open-sourced it, making it Intel's largest open-source commitment to date.
The aim of TBB, which I've described in previous coverage of Intel's multicore compilers, is to make it easier for coders in C++ to express task-level parallelism. TBB works by abstracting parallelism above the level that most programmers are currently used to, especially those coders who use POSIX or Windows threads. Coders can use the TBB template library in conjunction with the platform's native threads, and the different pieces of the project (task scheduler, mutex locks, atomic operations, containers, etc.) can be used independently of one another.
