  3. Hoard

    The Hoard Memory Allocator: A Fast, Scalable, and Memory-efficient Malloc for Linux, Windows, and Mac.

  4. Heap-Layers

    Heap Layers: An Extensible Memory Allocation Infrastructure

  5. o1heap

    Constant-complexity, deterministic, very fast memory allocator (heap) for hard real-time high-integrity embedded systems. Allocation takes ≈165 cycles on Cortex M4. There is little activity because the project is finished and does not require further changes.

  6. memorymanager

    A simple, thread-safe memory manager for 64bit C++ applications and games. Focus is on preventing heap fragmentation in the absence of good virtual memory management, at the cost of wasting some memory. It works by globally overriding the new and delete operators.

  7. RTSHA

    Real Time Safety Heap Allocator
