A Dynamic Migration Algorithm for a Distributed Memory-Based File Managementsystem
نویسندگان
چکیده
Conventional migration strategies attempt to evenly balance the load across all available server machines. This paper discusses why conventional migration approaches are not necessarily appropriate for distributed memorybased file systems and presents and alternative approach that spreads data (possibly unevenly) across as few machines as possible and involves other available machines only as needed. The main advantage of our approach is that it keeps the system minimally distributed thereby reducing the failure rate among servers, the communication overhead among servers, the time needed to compute data relocation, distributed addressing costs, and the probability of unanticipated migrations (e.g., caused by, and an inconvenience to,

Adaptive Dynamic Data Placement Algorithm for Hadoop in Heterogeneous Environments
Hadoop MapReduce framework is an important distributed processing model for large-scale data intensive applications. The current Hadoop and the existing Hadoop distributed file system’s rack-aware data placement strategy in MapReduce in the homogeneous Hadoop cluster assume that each node in a cluster has the same computing capacity and a same workload is assigned to each node. Default Hadoop d...
متن کاملChaotic Genetic Algorithm based on Explicit Memory with a new Strategy for Updating and Retrieval of Memory in Dynamic Environments
Many of the problems considered in optimization and learning assume that solutions exist in a dynamic. Hence, algorithms are required that dynamically adapt with the problem’s conditions and search new conditions. Mostly, utilization of information from the past allows to quickly adapting changes after. This is the idea underlining the use of memory in this field, what involves key design issue...
متن کاملClustering and Memory-based Parent-Child Swarm Meta-heuristic Algorithm for Dynamic Optimization
So far, various optimization methods have been proposed, and swarm intelligence algorithms have gathered a lot of attention by academia. However, most of the recent optimization problems in the real world have a dynamic nature. Thus, an optimization algorithm is required to solve the problems in dynamic environments well. In this paper, a novel collective optimization algorithm, namely the Clus...

متن کاملIntroducing a new meta-heuristic algorithm based on See-See Partridge Chicks Optimization to solve dynamic optimization problems
The SSPCO (See-See Particle Chicks Optimization) is a type of swarm intelligence algorithm derived from the behavior of See-See Partridge. Although efficiency of this algorithm has been proven for solving static optimization problems, it has not yet been tested to solve dynamic optimization problems. Due to the nature of NP-Hard dynamic problems, this algorithm alone is not able to solve such o...
