A technique for workload balancing on distributed visualization clusters is suggested. The round-robin scheduling of partial object geometry “chunks” avoids render node starvation and balances the data backlog in the send buffers of the geometry nodes. Because frame synchronization requires that all send buffers drain, balancing these send buffer backlogs is seen to substantially improve frame ...

Three-body effects play an important role for obtaining quantitatively high accuracy in a variety of molecular simulation applications. However, evaluation of three-body potentials is computationally costly, generally of O(N3) where N is the number of particles in a system. In this paper, we present a loadbalancing workload distribution scheme for calculating three-body interactions by taking a...

Real-time visualization is an important tool for immediately inspecting results for scientific simulations. Graphics Processing Units (GPUs) as commodity computing devices offer massive parallelism that can greatly improve performance for data-parallel applications. However, a single GPU provides limited support which is only suitable for smaller scale simulations. Multi-GPU computing, on the o...

Workload and resource management are two essential functions provided at the service level of the grid software infrastructure. To improve the global throughput of these software environments, workloads have to be evenly scheduled among the available resources. To realize this goal several load balancing strategies and algorithms have been proposed. Most strategies were developed in mind, assum...

Nursing workload in hospitals has an impact on the quality of care and on job satisfaction. Understandably there has been much recent research on improving the staffing and nurse-patient assignment decisions in increasingly realistic settings. On a version of the nursepatient assignment problem given a fixed staffing of neonatal intensive care units, constraint programming (CP) was shown to per...

Recent advancement in computer graphics and inter-networking technologies enable researchers to experiment and build the distributed virtual environment (DVE) system. In general, a DVE system allows many clients to simultaneously explore a virtual world (which is a high resolution 3D environment representing a real life community) and at the same time, users in this virtual environment can inte...

Cell planning has been a long-standing problem since the very starting commercialization of mobile communications, ofwhich power coverage and capacity coverage are twomajor objectives. In this paper, we develop a novel cell planning scheme that is effective and efficient for both the conventional cellular systems and the arising heterogeneous networks, e.g., the long term evolution advanced (LT...

Virtual Reality (VR) has grown to become state-of-theart technology in many businessand consumer oriented E-Commerce applications. One of the major design challenges of VR environments is the placement of the rendering process. The rendering process converts the abstract description of a scene as contained in an object database to an image. This process is usually done at the client side like i...

This paper addresses the issue of dynamic load imbalance in a class of synchronous iterative applications, and develops a model to represent their workload dynamics. Such models of application load dynamics help in more accurate performance prediction and in the design of efficient load balancing algorithms. Our model captures the workload dynamics across iterations, and predicts the workload d...
