The Tor network is probably one of the most popular online anonymity systems in the world. It has been built based on the volunteer relays from all around the world. It has a strong scientific basis which is structured very well to work in low latency mode that makes it suitable for tasks such as web browsing. Despite the advantages, the low latency also makes Tor insecure against timing and tr...

Observational determinism has been proposed in the literature as a way to ensure confidentiality for multi-threaded programs. Intuitively, a program is observationally deterministic if the behavior of the public variables is deterministic, i.e., independent of the private variables. Several formal definitions of observational determinism exist, but all of them have shortcomings; for example the...

The proliferation of information technology produces a huge amount data called big that cannot be processed by traditional database systems. These Various types come from different sources. However, stragglers are major bottleneck in processing, and hence the early detection accurate identification can have important impacts on performance processing. This work aims to assess five methods: Hado...

The rapid development of wearable computing technologies has led to an increased involvement devices in the daily lives people. main power sources are batteries; so, researchers must ensure high performance while reducing consumption and improving battery life devices. purpose this study is analyze new features Energy-Aware Scheduler (EAS) Android 7.1.2 operating system scarcity EAS schedulers ...

Efficient resource scheduling is essential for maximal utilization of expensive deep learning (DL) clusters. Existing cluster schedulers either are agnostic to machine (ML) workload characteristics, or use heuristics based on operators' understanding particular ML framework and workload, which less efficient not general enough. In this article, we show that DL techniques can be adopted design a...

The SCSI or the fibre channel (FC) disk drive, called SCSI-FC disk drive has its own internal queue and internal scheduler which maximize its own throughput. The request service order scheduled by the block device drive in Linux is changed by the disk internal scheduler (DIS) and we call this reordering. The conventional real-time disk schedulers are based on Linux block device driver, and the ...

In this paper, we consider the problem of determining a cyclic (or loop) scheduler that allocates slots to flows as periodically as possible. We use the second moment of the inter-allocation distance for each flow as its periodicity metric. We establish the optimality of a Weighted-Round Robin with spreading (WRR-sp2) scheduler for a two-flow scenario. We consider a class-based scheduling scena...
