Abstract--Many shared-memory parallel systems use lockbased synchronization mechanisms to provide mutual exclusion or reader-writer access to memory locations. Software locks are i...

We argue that traditional synchronization objects, such as locks, conditions, and atomic/volatile variables, should be defined in terms of transactions, rather than the other way ...

Many programs exploit shared-memory parallelism using multithreading. Threaded codes typically use locks to coordinate access to shared data. In many cases, contention for locks r...
