Nettet12. jan. 2024 · Hoard allocator — A Fast, Scalable, and Memory-efficient Malloc for Linux, Windows, and Mac. kmalloc – выделение памяти для объектов, меньших размера страницы в ядре Linux. CAMA – предсказуемый cache-aware аллокатор. NettetThis memory management library sees the malloc heap as an array of blocks, and uses block numbers to keep track of locations. The block numbers are 15 bits - which allows for up to 32767 blocks of memory. The high order bit marks a block as being either free or in use, which will be explained later.

http://locklessinc.com/benchmarks_allocator.shtml NettetHoard will always improve the performance of multithreaded programs running on multiprocessors that make frequent use of the heap (calls to malloc/free or new/delete, as well as many STL functions). Because Hoard avoids false sharing, Hoard also speeds up programs that only occasionally call heap functions but access these objects frequently.
