Flashing up the storage hierarchy
The focus of this thesis is on systems that employ both flash and magnetic disks as storage media. Considering the widely disparate I/O costs of flash disks currently on the market, our approach is a cost-aware one: we explore techniques that exploit the I/O costs of the underlying storage devices to improve I/O performance. We also study the asymmetric I/O properties of magnetic and flash disk...
متن کاملSecure Software Flashing
An increasing number of vehicular electronic control units (ECU) are equipped with reprogrammable flash memory. The software program in the flash memory determines the behavior of the ECU. The program code usually can be updated via a bootloader, e.g., for a firmware update, a bug fix, or an update enabling additional functionality. The download might be performed over a diagnostic channel or i...
متن کاملRemarks about the Flashing Rachet
The flashing rachet is the simplest example of diffusion mediated transport as well as the suggested mechanism for a class of protein motors. Here we briefly explain these concepts and give an entropy based argument for existence and uniqueness of a model problem. We also examine the features of the system that lead to transport
متن کاملFlashing up the storage layer
In the near future, commodity hardware is expected to incorporate both flash and magnetic disks. In this paper we study how the storage layer of a database system can benefit from the presence of both kinds of disk. We propose using the flash and the magnetic disk at the same level of the memory hierarchy and placing a data page to only one of these disks according to the workload of the page. ...
متن کاملDiffusion mediated transport and the flashing ratchet
Diffusion mediated transport is a phenomenon in which a unidirectional motion of particles is achieved as a result of two opposing tendencies: diffusion, which spreads the particles uniformly through the medium and transport, which concentrates the particles at some special sites. The flashing ratchet version of the Brownian motor, a simple model for protein motors, where the switching between ...
