Fast General Distributed Transactions with Opacity
Aleksandar Dragojevic, Stanko Novakovic, Georgios Chatzopoulos
Transactions can simplify distributed applications by hiding data distribution, concurrency, and failures from the application developer. Ideally the developer would see the abstraction of a single large machine that runs transactions sequentially and neve ...
ASSOC COMPUTING MACHINERY2019Scalable Synchronization in Shared-Memory Systems: Extrapolating, Adapting, Tuning
As hardware evolves, so do the needs of applications. To increase the performance of an application,
there exist two well-known approaches. These are scaling up an application, using a larger multi-core
platform, or scaling out, by distributing work to mul ...
EPFL2018SPADE: Tuning scale-out OLTP on modern RDMA clusters
Rachid Guerraoui, Aleksandar Dragojevic, Georgios Chatzopoulos
Distributed transactions on modern RDMA clusters promise high throughput and low latency for scale-out workloads. As such, they can be particularly beneficial to large OLTP workloads, which require both. However, achieving good performance requires tuning ...
Association for Computing Machinery2018Abstracting Multi-Core Topologies with MCTOP
Rachid Guerraoui, Vasileios Trigonakis, Georgios Chatzopoulos
Portability and efficiency are usually antagonists in multi-core computing. In order to develop efficient code, one needs to take into account the topology of the target multi-cores (e.g., for locality). This clearly hampers code portability. In this paper ...
