Intel Threading building blocks

Overview - Intel Threading Building Blocks (IntelTBB) is a C++ library that simplifies threading for performance - Move the level at which you program from threads to tasks - Let the run-time library worry about how many threads to use, scheduling, cache etc. - Committed to: compiler independence, processor independence, OS independence

Benefits of TBB - Intel Threading Building Blocks enables you to specify a task instead of threads - Intel Threading Building Blocks targets threading performance - Intel Threading Building Blocks is compatible with other threading packages - Intel Threading Building Blocks emphasizes scalable data parallel programming - Intel Threading Building Blocks relies on generic programming

TBB is a collection of components for parallel programming: - Basic algorithms: parallel_for, parallel_reduce, parallel_scan - Advanced algorithms: parallel_while, parallel_do, parallel_pipeline, parallel_sort - Containers: concurrent_queue, concurrent_priority_queue, concurrent_vector, concurrent_hash_map - Memory allocation: scalable_malloc, scalable_free, scalable_realloc, scalable_calloc, scalable_allocator, cache_aligned_allocator - Mutual exclusion: mutex, spin_mutex, queuing_mutex, spin_rw_mutex, queuing_rw_mutex, recursive_mutex - Atomic operations: fetch_and_add, fetch_and_increment, fetch_and_decrement, compare_and_swap, fetch_and_store
