Hyder - A Transactional Record Manager for Shared Flash
Hyder supports reads and writes on indexed records within classical multi-step transactions. It is designed to run on a cluster of servers that have shared access to a large pool ...

Model checking transactional memories
Model checking software transactional memories (STMs) is difficult because of the unbounded number, length, and delay of concurrent transactions and the unbounded size of the memo...

Experimental Evaluation of Real-Time Optimistic Concurrency Control Schemes
Due to its potential for a high degree of parallelism, optimistic concurrency control is expected to perform better than two-phase locking when integrated with priority-driven CPU...

Dynamic Real-Time Optimistic Concurrency Control
In a recent study, we have shown that in real-time database systems that discard late transactions, optimistic concurrency control outperforms locking. Although the optimistic alg...

Using Dynamic Adjustment of Serialization Order for Real-Time Database Systems
Studies in [7,8, 91 concluded that for a variety of reasons, optimistic concurrency control appears well-suited to real-time database systems. Especially, they showed that in a re...
