An object storage system comprises one or more computer processors or threads that can concurrently access a shared memory, the shared memory comprising an array of equally-sized cells. In one embodiment, each cell is of the size used by the processors to represent a pointer, e.g., 64 bits. Using an algorithm performing only one memory write, and using a hardware-provided transactional operation, such as a compare-and-swap instruction, to implement the memory write, concurrent access is safely accommodated in a lock-free manner.
