oneTBB is happy to introduce 2023.1.0 release!

What's New

[Preview] NUMA Optimization: Use new interleaved memory allocation APIs to explicitly control memory placement across NUMA nodes. The allocate_numa_interleaved and deallocate_numa_interleaved functions allocate and deallocate memory across multiple NUMA nodes, helping increase bandwidth and avoid bottlenecks from single-node allocation.

[Preview] C++20 Modules: This release adds experimental support for C++20 modules with the introduction of include/oneapi/tbb.cppm. Developers can use this instead of traditional headers to reduce compilation times and improve encapsulation.

oneTBB repository now contains Thread Composability Manager (TCM) source code - a project that helps in limiting oversubscription that can arise when multiple parallel runtimes are used within an application.

oneTBB is happy to introduce 2023.0.0 release!

What's New

[Preview] Introduced ability to wait for a single task in a task_group instead of waiting for all tasks to finish. This increases reactivity and decreases latency in key user workloads.
[Preview] Introduced flow::resource_limited_node and flow::resource_limiter classes. These nodes only execute when they can successfully acquire the necessary resources from the resource limiters associated with the node. This feature is used to guard access to shared resources, while maximizing available parallelism in the graph.
[Preview] Introduced task_arena core type selector to better support hybrid architectures with several core types. Users use this new flexible API to more tightly constrain execution to set preferences for the specific core types that match their workload.
[Preview] Added global control parameter to set default block time behavior on server HW. This allows developers to revert to older blocking behavior if their applications are not able to fully utilize all cores, thereby reducing idle spinning.
Added new API to create a set of NUMA bound task arenas, simplifying common patterns used to optimize for NUMA architectures.
Extended Flow Graph functional node deduction guides to support non-static member function and member object pointers as a node bodies.
The Flow Graph join_node and indexer_node now support 10 or more input ports.
Explicit deduction guides for blocked_nd_range are now a fully supported feature.
Added native WASM exception handling support.

2022.3.022 Oct 2025

oneTBB is happy to introduce 2022.3.0 release!

What's New

[Preview] Introduced API for setting dynamic task dependencies in task_group. This allows successor tasks to execute only after all their predecessors have completed.
Extended task_arena with API support for enqueuing functions into a task_group and waiting for the task_group to complete.
Introduced API for setting and getting the assertion handler. This allows applications to set their own assertion handling functions.

What's New

2021.6.027 Apr 2022

oneTBB is happy to introduce 2021.6.0 release!

What's New

:white_check_mark: New Features

Improved support and use of the latest C++ standards for parallel_sort that allows using this algorithm with user-defined and standard library-defined objects with modern semantics.
The following features are now fully functional: task_arena extensions, collaborative_call_once, adaptive mutexes, heterogeneous overloads for concurrent_hash_map, and task_scheduler_handle.
Added support for Windows* Server 2022 and Python 3.10.

:hammer: Fixed Issues

Memory allocator crash on a system with an incomplete /proc/meminfo (GitHub* #584).
Incorrect blocking of task stealing (GitHub* #478).
Hang due to incorrect decrement of a limiter_node (GitHub* #634).
Memory corruption in some rare cases when passing big messages in a flow graph (GitHub* #639).
Possible deadlock in a throwable flow graph node with a lightweight policy. The lightweight policy is now ignored for functors that can throw exceptions (GitHub* #420).
Crash when obtaining a range from empty ordered and unordered containers (GitHub* #641).
Deadlock in a concurrent_vector resize() that could happen when the new size is less than the previous size (GitHub* #733).

See our Release Notes to learn more about known limitations and new features.
