Pathway Analyst (Path-A) is a publicly available web server (http://path-a.cs.ualberta.ca) that predicts metabolic pathways. It takes a FASTA format file containing a set of query protein sequences from a single organism (a partial or complete proteome) and identifies those sequences that are likely to participate in any of its supported metabolic pathways (currently 10). Path-A uses a number o...

In order to ensure the effect of network data transmission in scientific research institutions and avoid information from being attacked damaged, a secure sharing method based on multi-layer encryption technology is proposed. Combined with technology, security protocol constructed integrity initial file. The evaluation system further constructed. path tracked, evaluated tested real time. platfo...

Recent GPUs enable Peer-to-Peer Direct Memory Access (P2P) from fast peripheral devices like NVMe SSDs to exclude the CPU from the data path between them for efficiency. Unfortunately, using P2P to access files is challenging because of the subtleties of low-level nonstandard interfaces, which bypass the OS file I/O layers and may hurt system performance. SPIN integrates P2P into the standard O...

Device scaling and large integration increase the vulnerability of microprocessors to transient errors. One of the structures where errors can be most harmful is the register file, because it is part of the architectural state. Moreover, because the register file is frequently read, an error can quickly propagate to other parts of the processor. This paper presents Shield, a novel, cost-effecti...

Peer-to-Peer (P2P) overlay networks and Mobile Ad-hoc Networks (MANETs) share many key characteristics such as self-organization and decentralization; they also face the crucial challenge of providing connectivity in a decentralized, dynamic environment. However, when considering ad-hoc networks composed by mobile devices such as smartphones, we cannot rely on the continuous end-to-end path bet...

This paper proposes using file system custom metadata as a bidirectional communication channel between applications and the storage middleware. This channel can be used to pass hints that enable cross-layer optimizations, an option hindered today by the ossified file-system interface. We study this approach in the context of storage system support for large-scale workflow execution systems: Our...

We present a new file system that combines name-based and content-based access to files at the same time. Our design allows both methods to be used at any time, thus preserving the benefits of both. Users can create their own name spaces based on queries, on explicit path names, or on any combination interleaved arbitrarily. All regular file opemtions such as adding, deleting, or moving files a...
