Transactions on Mergeable Objects

  title={Transactions on Mergeable Objects},

Destructible updates on shared objects require careful handling of concurrent accesses in multi-threaded programs. Paradigms such as Transactional Memory support the programmer in correctly synchronizing access to mutable shared data by serializing the transactional reads and writes. But under high contention, serializable transactions incur frequent aborts and limit parallelism. This can lead to a severe performance degradation. In this paper, we propose mergeable transactions which provide a… CONTINUE READING
