xCalls: safe I/O in memory transactions
Memory transactions, similar to database transactions, allow a programmer to focus on the logic of their program and let the system ensure that transactions are atomic and isolate...

A Trace Semantics for Long-Running Transactions
Abstract. A long-running transaction is an interactive component of a distributed system which must be executed as if it were a single atomic action. In principle, it should not be...
