Adaptative Partitioning and Dynamic
نویسنده
چکیده
Dynamic load balancing and migration are two main mechanisms to increase system throughput and to reduce application response time. These mechanisms become very complex (and time consuming) to manage, when the computing system increases in scale and heterogeneity. We have proposed the Territory Model in 14] that separates the system in Computational Domains, where each domains manage its resources by means of Resource Territories, and its application by means of Execution Territories. This paper presents performance evaluations of our model, applied to parallel machines management. The load balancing algorithm associated to each Execution Territory is based on force computation between processes and nodes. Measures are compared with random and diiusion algorithms , and show that our model is eecient, adaptable and scalable with a low system overhead.

متن کاملDesign and Evaluation of a Method for Partitioning and Offloading Web-based Applications in Mobile Systems with Bandwidth Constraints
Computation offloading is known to be among the effective solutions of running heavy applications on smart mobile devices. However, irregular changes of a mobile data rate have direct impacts on code partitioning when offloading is in progress. It is believed that once a rate-adaptive partitioning performed, the replication of such substantial processes due to bandwidth fluctuation can be avoid...

This research focuses on proposing an optimal trajectory planning and control method of two link rigid-flexible manipulators (TLRFM) for Dynamic Object Manipulation (DOM) missions. For the first time, achievement of DOM task using a rotating one flexible link robot was taken into account in [20]. The authors do not aim to contribute on either trajectory tracking or vibration control of the End-...
