The increasing complexity of modern and future multi-core/multithreaded processors rises the question of how to best utilize processor resources. On one side, Amdahl’s Law limits the maximum theoretical speedup of parallel applications while, on the other side, the increasing complexity of runtime programming language may introduce implicit serialization points. Several studies demonstrated tha...

The management of scarce groundwater resources involves numerous complex challenges, not least developing appropriate allocation limits for extraction and establishing efficient and equitable allocation between competing uses at various interacting scales. Practitioners, lawmakers and scholars continue to struggle with designing water governance approaches that adequately address these challeng...

this research presents a mathematical model for oil and gas optimal allocation to different sectors in iran using operations research techniques. sectors are residential and commercial, transportation, industries, agriculture, exports, injection to oil reservoirs and power plans as a secondary energy producer. optimal allocation of energy resources to end-uses from 2011 to 2021 has been done us...

The inter-cell interference (ICI) problem in OFDMA wireless systems is a major impediment to attain high rates particularly for cell-edge users in reuse-1 systems. Using centralized resource allocation to combat ICI is not practical, particularly in heterogeneous networks (HetNets), as they require intensive signalling about interference and channel state information that may not always be prac...

We develop an approach for the automatic and elastic management of memory in shared clusters executing data analytics applications. Our approach, called ElasticMem, comprises a technique for dynamically changing memory limits in Java virtual machines, models to predict memory usage and garbage collection cost, and a scheduling algorithm that dynamically reallocates memory between applications. ...

This paper highlights the need for adaptive resource management within the endsystem, in addition to the provision of basic QoS guarantees, in order to maximize the users’ perceived performance of their applications at any given time within the limits of the physical resources available. A prototype system developed within the Nemesis multimedia operating system [7] is described. The system pro...

This paper presents a monetary-theoretic model to study the implications of networks’ collection of personal identifying data and data security on each other’s incidence and costs of identity theft. To facilitate trade, agents join clubs (networks) that compile and secure data. Too much data collection and too little security arise in equilibrium with noncooperative networks compared with the e...

A general allometric model has been derived to predict intraspecific and interspecific scaling relationships among seed plant leaf, stem, and root biomass. Analysis of a large compendium of standing organ biomass sampled across a broad sampling of taxa inhabiting diverse ecological habitats supports the relations predicted by the model and defines the boundary conditions for above- and below-gr...

We study the implementation of dense linear algebra computations, such as matrix multiplication and linear system solvers, on two-dimensional (2D) grids of heterogeneous processors. For these operations, 2D-grids are the key to scalability and eÆciency. The uniform block-cyclic data distribution scheme commonly used for homogeneous collections of processors limits the performance of these opera...

The generalized Pólya urn has been extensively studied and is widely applied in many disciplines. An important application of urn models is in the development of randomized treatment allocation schemes in clinical studies. The randomly reinforced urn was recently proposed, but, although the model has some intuitively desirable properties, it lacks theoretical justification. In this paper we obt...
