Distributed file systems in an authentication system
Typescript (photocopy).

The Jade File System.
File systems have long been the most important and most widely used form of shared permanent storage. File systems in traditional time-sharing systems such as Unix support a coherent sharing model for multiple users. Distributed file systems implement this sharing model in local area networks. …

FlexGP : a scalable system for factored learning in the cloud
… data-parallel approach to cloud-based distributed learning using existing single-machine algorithms, without any dependence on distributed file systems or shared memory between instances. We design and implement asynchronous and decentralized launch and peer discovery protocols to start …

Dynamic resource provisioning for data center workloads with data constraints
… of stateless behaviors no longer holds for subsystems that subject to data constraints, as a request may depend on a certain dataset stored on a small subset of servers. Routing a request to a server without the required dataset violates data locality or data availability properties, which may …

ClusterRAID: Architecture and Prototype of a Distributed Fault-Tolerant Mass Storage System for Clusters
… have replaced the traditionally used integrated systems due to their better price/performance ratio. As paradigms shift from mere computing intensive to I/O intensive applications, mass storage solutions for cluster installations become a more and more crucial aspect of these systems. The …

Towards a worldwide storage infrastructure
Peer-to-peer systems have recently gained a lot of attention in the academic community especially through the design of KBR (Key-Based Routing) algorithms and DHT (Distributed Hash Table)s. On top of these constructs were built promising applications such as video streaming applications but also …

Content-aware compression for big textual data analysis
… to support text-based big data analysis in distributed environments. The novel contributions of this work include the following. Firstly, a Content-aware Partial Compression (CaPC) scheme is developed. CaPC makes a distinction between informational and functional content in which only the …

High Performance Inter-kernel Communication and Networking in a Replicated-kernel Operating System
… four contributions. First, it introduces a filesystem for Popcorn, which is a vital part to provide a SSI. Popcorn supports thread/process migration that requires migration of file descriptors which is not provided by traditional filesystems as well as popular distributed file systems, this …

Improving capacity-performance tradeoffs in the storage tier
… with these new techniques, large sequential file accesses. The trend toward bigger files exists to help amortize the cost of data accesses from the storage layer, as many workloads are recognized to be I/O bound. The storage layer is widely recognized as the slowest layer in the system. This …

Coherencia de Cache en Sistemas de Ficheros para Entornos Distribuidos y Paralelos
… in processors, memories and communication subsystems, has led the I/O subsystems to become a bottleneck in many computer systems. This problem, defined as the I/O crisis, has been mainly addressed using parallelism and caching in the I/O subsystem. Caching improves I/O performance, both for …

DecaFS: A Modular Distributed File System to Facilitate Distributed Systems Education
… factors encourage industry developers to build distributed systems and use distributed services. Software engineers are therefore exposed to distributed systems and services daily in the workplace. However, distributed computing is hard to teach in Computer Science courses due to the complexity …
