METHOD FOR BUILDING A RANKED REGISTER AND A COMPARE-AND-SWAP OBJECT, A RANKED REGISTER AND COMPARE-AND-SWAP-OBJECTS

摘要

A method is used to build a concurrent data structure in the form of a ranked register based on a Compare-And-Swap (CAS) functionality and an according ranked register, to allow reliable access of shared data within a storage by multiple clients. Read and write operations are defined within the ranked register. The read operation takes a rank as argument and returns a rank-value pair. The write operation takes a rank-value pair as argument and returns either commit or abort. The read operation returns a rank-value pair that was written in a previous write operation.
