摘要
In one embodiment a memory management method uses a third finger fetching pointer thread operating on memory objects distributed in a second memory space between a scan pointer thread and an allocation pointer thread to fetch objects in the second memory space prior to them being scanned. The fetching thread is moved to a next memory slot in the second memory space when the scanned memory slot does not hold a pointer to an object in the first memory space. The memory object is prefetched into a cache shared with an allocation pointer thread when the scanned memory slot holds a pointer to an object in the first space.
