Bloom Filters for Filesystem Forensics
Digital forensics investigations become more time consuming as the amount of data to be investigated grows. Secular growth trends between hard drive and memory capacity just exacerbate the problem. Bloom filters are space-efficient, probabilistic data structures that can represent data sets with …

Certifying checksum-based logging in the RapidFSCQ crash-safe filesystem
… underlying RapidFSCQ, a certified crash-safe filesystem, to support formally verified checksums. An evaluation of RapidFSCQ shows that it enables end-to-end verification of application and filesystem crash safety, and that RapidFSCQ's optimizations, including checksumming, achieve I/O …

VM2Docker : automating the conversion from virtual machine to docker container
… the past year and provides a powerful layered filesystem to improve deployability and provide space savings for those containers that share many layers in common. As of this writing, there is no system for automatically converting VMs to containers, as all configuration must be done manually. …

Exploring the Boundaries of Operating System in the Era of Ultra-fast Storage Technologies
… the OS storage stack particularly the Virtual Filesystem (VFS) and filesystem layer are increasingly becoming a scalability bottleneck. Applications bypass the kernel (kernel-bypass storage stack) completely to eliminate the storage stack from becoming a performance and scalability bottleneck. …

Octavio: A Distributed System for the Sensing, Storing, and Retrieval of Piano Playing Data
… campus, constructed a matching database and filesystem of all playing sessions across time, and established a public API for the retrieval of this data. The collected data will later be used to power a publicly accessible webpage of real-time and historical visualizations, as well as serve to …

Automated Rehosting and Instrumentation of Embedded Firmware
… applying various failure-oblivious, network, and filesystem fixes necessary to enable web service operation. On successfully emulated systems, ARI further instruments and tests embedded web servers using the popular dynamic analysis tool, Valgrind. On a corpus of 1709 Linux-based firmware samples, …

Optimizing SigmaOS for Efficient Orchestration of Fault-Tolerant, Burst-Parallel Workloads
… where resources are accessed through a Unix-like filesystem interface, and supports applications built from procs—lightweight, rapidly-spawnable programs that can be both short-lived for bursty tasks or long-running and stateful for persistent services. However, the current prototype exhibits …

Storage system design for non-volatile byte-addressable memory using consistent and durable data structures
… the file interface which provides access to a filesystem, which in turn uses the block layer to provide access to hard disk drives or solid state disks. With the advent of non-volatile byte-addressable memory (NVBM), buffered I/O systems designed primarily for hard disks are no longer the most …

Privacy engineering for social networks
… It is the foundation for a practical shared filesystem, a perfectly unobservable communications channel and a distributed application platform. The Footlights application platform allows third-party developers to write social applications without direct access to users' private data. …

A hierarchical group model for programming sensor networks
… FUSN, provides a set of methods for constructing filesystem-based interfaces for sensor networks. This demonstrates the general applicability of the model as applied to sensor network programming and management interfaces. Finally, the model is applied to a novel privacy algorithm to demonstrate …

Environment for Large Data Processing and Visualization Using MongoDB
… to record file paths and stored files in a filesystem to manage data. By using this method, we do not need to create different schemas for different files. The system offers users basic data processing methods, such as distribution frequency histograms. It also provides scientific models for …
-
Partial Replica Location And Selection For Spatial Datasets
… a model for disk access performance that takes filesystem prefetching into account and is sufficiently accurate for spatial replica selection. Making a few simplifying assumptions, we present a fast replica selection algorithm for partial spatial replicas. The algorithm uses a greedy approach …
-
Scalability Analysis and Optimization for Large-Scale Deep Learning
… This includes data movement needed from the filesystem, within the network subsystem, and even within the node itself, all of which limit the scalability of DL frameworks on large systems. Even after data is moved to the computational units, managing this data is not easy. Modern DL …

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 …

Exploring a resource allocation security protocol for secure service migration in commercial cloud environments
… This service was used as the backend of a FUSE filesystem. The results show that this approach can be safely implemented and should perform well in real environments.

Analyzing & designing the security of shared resources on smartphone operating systems
… mobile application adversary exploiting shared filesystem and permission resources; and shows how a mobile app adversary can exploit shared communication mediums to compromise the confidentiality of the data collected by external devices (e.g. fitness and medical accessories, NFC tags etc.). …
