PURPOSE The aim of the study is to define the impact of exercise on a treadmill on static balance and stability of posture in a group of patients after cerebral stroke rehabilitated in a late period, with an application of a treadmill with the function of visual biofeedback. METHODS The examination was carried out in a group of 46 people in a late period after ischemic cerebral stroke. The pa...

High performance clusters are being configured specially to give data centers that require extreme performance and the processing power they need. When the data is accessed across clusters the data latency time has significant impact on the performance. In the literature it is given that memory and I/O have become the new bottleneck, instead of processing power in achieving efficient load balan...

This paper considers policies for distributing requests in clustered Web servers, wherein multiple server machines are conngured to function as a single high(er) performance Web server. We evaluate various load distribution policies with respect to both their ability to achieve good load balance (the primary goal) and also to their impact on the eeec-tiveness of per-machine caching. Trace-drive...

A parallel scheduling algorithm for N-cube networks is presented in this paper. This algorithm can fully balance the load and maximize locality by using global load information. Communication costs are significantly reduced compared to other existing algorithms.

Coupled model development presents a set of challenges broadly called the coupling problem; message-passing parallelism complicates matters, resulting in the parallel coupling problem. Performance tuning of parallel coupled systems is complex and performed largely in an ad hoc fashion; from the domain scientist’s perspective the figure of merit is throughput, which is the amount of simulation a...

The CPU processing speed and disk capacity are increasing tremendously during the past decade. However, the even faster increasing number of users generates higher requirements for high performance and huge capacity computer systems. More and more applications are now running on distributed systems. Load balance is an important issue in distributed storage systems. Currently, very few of them h...

The efficiency of MapReduce is closely related to its load balance. Existing works on MapReduce load balance focus on coarse-grained scheduling. This study concerns finegrained scheduling on MapReduce operations, with each operation representing one invocation of the Map or Reduce function. By default, MapReduce adopts the hash-based method to schedule Reduce operations, which often leads to po...

Abstract—This work considers secure transmission protocol for flexible load-balance control in two-hop relay wireless networks without the information of both eavesdropper channels and locations. The available secure transmission protocols via relay cooperation in physical layer secrecy framework cannot provide a flexible load-balance control, which may significantly limit their application sco...
