![]() The frontend acts as a caching layer, holding objects inside two storage types viz. OneTBB memory allocator consists of two distinct layers: frontend and backend ( Figure 1). General architecture of oneTBB memory allocator Supported for Windows*, Linux*, macOS*, and Android* applications, oneTBB can handle several tedious tasks such as adding parallelism to complex loop structures, memory allocation, and task scheduling. OneTBB is a flexible yet performant threading library that simplifies parallel programming in C++ across accelerated hardware. It introduces two similar templates, scalable_allocator and cache_aligned_allocator, to address the critical issues in parallel programming listed above. OneTBB's approach maintains and expands on the API of the Standard Template Library (STL) template class std::allocator. This blog focuses on one such memory allocator provided by the IntelĀ® oneAPI Threading Building Blocks (oneTBB) library. ![]() Numerous memory managers exhibit different efficiencies for different applications. Preventing false sharing and thread contention.Avoiding the reaching of cache-associativity limits.Keeping allocated memory hot in the CPU cache.Faster memory allocation and deallocation among threads.It is an even tougher task in parallel applications, which have challenging demands, including: Dynamic memory allocation is a primary consideration when developing and optimizing any software application.
