Microsoft Research releases mimalloc high-performance memory allocator

By PulseAugur Editorial · [1 sources] ·

Microsoft Research has released mimalloc, an open-source memory allocator designed for modern, high-concurrency applications and large memory footprints, particularly those involving large language models. This drop-in replacement for malloc and free offers bounded allocation times, low fragmentation, and minimal contention through atomic operations. Initially developed for Microsoft's Lean and Koka programming languages, mimalloc has since been integrated into various Microsoft services like Bing, as well as external projects such as CPython 3.13+ and Unreal Engine.
