Value-cognizant Speculative Concurrency Control
We describe SCC-kS, a Speculative Concurrency Control (SCC) algorithm that allows a DBMS to use efficiently the extra computing resources available in the system to increase the l...

Timeliness via Speculation for Real-Time Databases
Various concurrency control algorithms di er in the time when con icts are detected, and in the way they are resolved. In that respect, the Pessimistic and Optimistic Concurrency ...

Using Incorrect Speculation to Prefetch Data in a Concurrent Multithreaded Processor
Concurrent multithreaded architectures exploit both instruction-level and thread-level parallelism through a combination of branch prediction and thread-level control speculation. ...

Low overhead concurrency control for partitioned main memory databases
Database partitioning is a technique for improving the performance of distributed OLTP databases, since “single partition” transactions that access data on one partition do no...

Value Prediction for Speculative Multithreaded Architectures
The speculative multithreading paradigm (speculative threadlevel parallelism) is based on the concurrent execution of control-speculative threads. The efficiency of microarchitect...
