A method of accessing data in a shared-memory, parallel-processing computing system, comprises, on a first processing unit, receiving a reference for a data structure stored in a memory and a first value of a generation attribute associated with the data structure, waiting to receive an exclusive lock on the data structure, obtaining an exclusive lock on the data structure, receiving a second value of a second generation attribute associated with the data structure; and accessing the data structure only if the first generation attribute value and the second generation attribute value are identical. |
