Virtualization is becoming widely deployed in servers to efficiently provide many logically separate execution environments by reducing the demand for physical servers, so this approach reserves physical CPU resources. Nevertheless, it still consumes large amounts of storage because each virtual machine (VM) instance, needs its own multi-gigabyte disk image. Existing systems take efforts to red...

in recent years, routing has been the most focused area in ad hoc networks research. on-demand routing in particular, is widely developed in bandwidth constrained mobile wireless ad hoc networks because of its effectiveness and efficiency. most proposed on-demand routing protocols are built and relied on single route for each data session. whenever there is a link disconnection on the active ro...

Digital piracy, the sharing files of music on peer-to-peer (P2P) networks has been cited as the key threat to the music industry by distorting promoting plans of albums (Billboard.biz, 2009). To combat widespread digital piracy on file-sharing networks, the content industries have employed diverse anti-piracy strategies including pollution technologies and stronger copyright legislation for mus...

Enabling search alleviates the need for manual file management, allowing users to find files by the features that are most relevant to them. Despite the need for a comprehensive file system search, most file system indexing work has focused on adapting existing solutions such as the RDBMS or spatial trees to index files. Although a step in the right direction these approaches have focused their...

Distributed file systems benefit greatly from optimistic replication that allows clients to update any replica at any site. However, such systems face a new dilemma: Once data is updated at a replica site, when should it be shipped to others? In conventional file system workloads, most data is read by its writer, so it needs to be shipped only for administrative reasons. Unfortunately, shipping...

To support massive parallel threads context, GPGPUs use a huge register file. Due to their size, register file is one of the most power hungry logic in GPGPU. However, the current trends indicate that GPGPU register file size will continue to get even bigger as the demand for higher single instruction multiple thread (SIMT) parallelism increases, particularly in high performance application dom...

With BitTorrent-like protocols a client may download a file from a large and changing set of peers, using connections of heterogeneous and timevarying bandwidths. This flexibility is achieved by breaking the file into many small pieces, each of which may be downloaded from different peers. This paper considers an approach to peer-assisted on-demand delivery of stored media that is based on the ...

Dual spacization of publishing means emergence of digital publishing in online and offline virtual environments along with analogue publishing. Analogue publishing is a kind of publishing that is produced in the form of physical printed writings as they appear in a single paper, single or many pages newspapers and magazines and books, writings on leaves and pieces of trees, natural skin and lea...

The Log-structured File System (LFS) transforms random writes to a huge sequential one to provide superior write performance on storage devices. However, LFS inherently suffers from overhead incurred by cleaning segments. Specifically, when file system utilization is high and the system is busy, write performance of LFS degenerates significantly due to high cleaning cost. Also, in the newer fla...

0272-1732/00/$10.00  2000 IEEE The need to access anything from anywhere has increased the role of distributed file servers in computing. Distributed file systems provide local file system semantics for access to remote storage. This allows network clients to incorporate the remote storage into their local file system. File semantics are well understood by users and applications, making distri...
