Microsoft's mimalloc: A Scalable Memory Allocator

Microsoft Research has developed mimalloc, a scalable memory allocator designed to replace traditional malloc and free functions. With a compact codebase of around 12,000 lines, mimalloc efficiently handles memory allocation across multiple threads, reducing synchronization needs. It has been adopted in major services like Bing and integrated into platforms such as Unreal Engine. This allocator is particularly effective for applications with large memory demands, offering improved performance and reduced contention. Mimalloc's open-source nature and widespread use underscore its impact on modern memory management.
