Abstract This paper deals with the neglected issue of central banks’ social responsibility. Since banks exert “structural power” on economies as well societies, their power should be regulated and controlled by society through a reliable framework To that aim, this article sheds light ‘why’ ‘how’ bank’s responsibility: I suggest reforms in order to increase legitimacy, while being consistent ma...

The CELESTE experiment will be an Atmospheric Cherenkov detector designed to bridge the gap in energy sensitivity between current satellite and ground-based gamma-ray telescopes, 20 to 300 GeV. We present test results made at the former solar power plant, Themis, in the French Pyrenees. The tests confirm the viability of using a central tower heliostat array for Cherenkov wavefront sampling. 1 ...

— Dynamic virtual machine migration is a key technique technology in the cloud computing, an algorithm is proposed in this thesis, which is a dynamic resource scheduling based on minimum load imbalancing measurement. First of all, load balancer in scheduler judges the overload phenomenon; we need to migrate VM (Virtual Machine) on physical machine. Then, according to the records in load balanc...

During its melt cycle, an arc furnace causes disturbances of the electrical supply. Existing measurement techniques for this application lead to corrective rather than predictive compensation. The use of neural networks to control the compensation is being considered, in particular reinforcement learning strategies which require no pre-training and which can adapt to a dynamically changing envi...

Load balancing is an important issue in parallel numerical simulations. However, state-of-the-art libraries addressing this problem show several deficiencies: they are hard to parallelize, focus on small edgecuts rather than few boundary vertices, and often produce disconnected partitions. We present a distributed implementation of a load balancing heuristic for parallel adaptive FEM simulation...

We develop a novel load-balancing packet scheduler for parallel forwarding systems. By investigating flow level characteristics of Internet traffic, we are able to trace the root for load imbalance in hash-based loadsplitting schemes. Our scheduler capitalizes on the non-uniform flow reference pattern and especially the presence of a few high-rate flows in typical Internet traffic mix. We show ...

An increasing number of high-performance distributed systems are written in garbage collected languages. This removes a large class of harmful bugs from these systems. However, it also introduces high tail-latency do to garbage collection pause times. We address this problem through a new technique of garbage collection avoidance which we call BLADE. BLADE is an API between the collector and ap...

The Adaptive Parallelism Environment is introduced as a means of effectively utilizing MPP processing resources in a multi-programmed MIMD or distributed system. It achieves this by dynamically calculating the optimal number of threads for a given program at runtime. The optimality calculation considers both the number of processing elements available to handle additional workloads and the esti...

The number of internet users rapidly increases as the business relies more on the internet and intranet. Accordingly, the traffic on the Internet is increasing dramatically. The workload on the servers is also increasing rapidly so that servers will be easily overloaded for a short time. To overcome the overloading problem of the servers, it is necessary to increase system performance and avail...

Many scientific applications involve grids that lack a uniform underlying structure. These applications are often also dynamic in nature in that the grid structure significantly changes between successive phases of execution. In parallel computing environments, mesh adaptation of unstructured grids ti_rough selective refinemcnttcoarsening has proven to be an effective approach. However, achievi...
