Transactions in software components: Container-interposed transactions

The paper focuses on transaction context propagation in component-based software architectures, where every component is deployed into a container and client requests may be performed in the scope of a container-interposed transaction. In the existing commercial architectures such as EJB and COM+, the “single attribute approach” is used to specify the transaction context propagation. Being diff...

Toxic Transactions ∗

In Transactional Memory workloads, conflicts among transactions necessitate that some transactions either block, or else abort. The more common approach, aborting, is under-studied. Much effort has explored the use of schedulers and gatekeepers when the global abort rate is high. Handling short spikes in the abort rate, especially due to a single transaction with a high likelihood of conflict, ...

Elastic Transactions

This paper presents elastic transactions, a variant of the transactional model. Upon conflict detection, an elastic transaction might drop what it did so far within a separate transaction that immediately commits, and initiate a new transaction which might itself be elastic. Elastic transactions are a complementary alternative to traditional transactions, particularly appealing when implementin...

Geochemical Transactions

Background: Proteins of various compositions are required by organisms inhabiting different environments. The energetic demands for protein formation are a function of the compositions of proteins as well as geochemical variables including temperature, pressure, oxygen fugacity and pH. The purpose of this study was to explore the dependence of metastable equilibrium states of protein systems on...
