Improving OLTP Concurrency through Early Lock Release

Anastasia Ailamaki, Frederick Ryan Johnson, Manoussos Gavriil Athanassoulis, Radu Ioan Stoica

Since the beginning of the multi-core era, database systems research has restarted focusing on increasing concurrency. Even though database systems have been able to accommodate concurrent requests, the exploding number of available cores per chip has surf ...

Precise Velocity Control of a Hard Disk Drive

The ramp technology was integrated in the Hard Disk Drive a couple of years ago, this technology allows a safer parking position for the heads, but also allow the heads to fly closer from the media, increasing the data density. The Load and Unload operatio ...

Tashkent: Uniting Durability with Transaction Ordering for High-Performance Scalable Database Replication

Sameh Mohamed Elnikety, Fernando Pedone

In stand-alone databases, the functions of ordering the transaction commits and making the effects of transactions durable are performed in one single action, namely the writing of the commit record to disk. For efficiency many of these writes are grouped ...

Consistent Main-Memory Database Federations under Deferred Disk Writes

Rodrigo Malta Schmidt, Fernando Pedone

Current cluster architectures provide the ideal environment to run federations of main-memory database systems (FMMDBs). In FMMDBs, data resides in the main memory of the federation servers. FMMDBs significantly improve performance by avoiding I/O during t ...

On Multidimensional Data and Modern Disks

Anastasia Ailamaki

With the deeply-ingrained notion that disks can efficiently access only one dimensional data, current approaches for mapping multidimensional data to disk blocks either allow efficient accesses in only one dimension, trading off the efficiency of accesses ...

Walking Four Machines By The Shore

Anastasia Ailamaki

Recent studies have shown that the hardware behavior of database workloads is suboptimal when compared to scientific workloads, and have identified the processor and memory subsystem as the true performance bottlenecks, when running decision-support worklo ...

Dynamic power management for portable systems

Giovanni De Micheli, Luca Benini

Portable systems require long battery lifetime while still delivering high performance. Dynamic power management (DPM) policies trade off the performance for the power consumption at the system level in portable devices. In this work we present the time-in ...

3-Dimensional Disk-Based Optical Correlator

Demetri Psaltis

A total of 300 templates were stored as angularly multiplexed transmission holograms at multiple spots on a photopolymer disk. A novel correlator architecture is described and demonstrated that correlates all the templates against an input image within one ...

Benefits of an image-oriented parallel file system

Roger Hersch

Professionals in various fields such as medical imaging, biology, and civil engineering require rapid access to huge amounts of uncompressed pixmap image data. In order to fulfill these requirements, a parallel image server architecture is proposed, based ...
