Prompt Application-Transparent Transaction Revalidation in Software Transactional Memory
A Non‑blocking Global Virtual Time Algorithm with Logarithmic Number of Memory Operations

The increasing diffusion of shared-memory multi-core machines has given rise to a change in the design of Parallel Discrete Event Simulation (PDES) platforms. In particular, the possibility to share large amounts of memory by many worker threads has lead to a boost in the adoption of non-blocking...
Preemptive Software Transactional Memory
A Wait-Free Multi-word Atomic (1,N) Register for Large-Scale Data Sharing on Multi-core Machines

We present a multi-word atomic (1,N) register for multi-core machines exploiting Read-Modify-Write (RMW) instructions to coordinate the writer and the readers in a wait-free manner. Our proposal, called Anonymous Readers Counting (ARC), enables large-scale data sharing by admitting up to 2^(32) - 2...
ORCHESTRA: An Asynchronous Wait-Free Distributed GVT Algorithm
A Conflict-Resilient Lock-Free Calendar Queue for Scalable Share-Everything PDES Platforms

Emerging share-everything Parallel Discrete Event Simulation (PDES) platforms rely on worker threads fully sharing the workload of events to be processed. These platforms require efficient event pool data structures enabling high concurrency of extraction/insertion operations. Non-blocking event...
