Dryad: Distributed Data-Parallel Programs From Sequential Building Blocks

Dryad is a general-purpose distributed execution engine for coarse-grain data-parallel applications. A Dryad application combines computational "Vertices" with communication "Channels" to form a dataflow graph. Dryad runs the application by executing the vertices of this graph on a set of available computers, communicating as appropriate through files, TCP pipes, and...

Locking Key Ranges With Unbundled Transaction Services

To adapt database technology to new environments like cloud platforms or multi-core hardware, or to try anew to provide an extensible database platform, it is useful to separate transaction services from data management elements that need close physical proximity to data. With "Generic" transactional services of concurrency control and recovery...

Taking the Heat Off Transactions: Dynamic Selection of Pessimistic Concurrency Control

This paper investigates feedback-directed dynamic selection between different implementations of atomic blocks. The paper initially executes atomic blocks using STM with optimistic concurrency control. At runtime, one identifies "Hot" variables that cause large numbers of transactions to abort. For these variables one selectively switches to using pessimistic concurrency control, in...
