Network-Aware HEFT Scheduling for Grid
We present a network-aware HEFT. The original HEFT does not take care of parallel network flows while designing its schedule for a computational environment where computing nodes are physically at distant locations. In the proposed mechanism, such data transfers are stretched to their realistic completion time. A HEFT schedule with stretched data transfers exhibits the realistic makespan of the...
متن کاملNetwork-Aware Grid Scheduling
Network links, as the communication media for Grid transmissions, should be considered as a parameter to decide about the convenience of using other different resources, such as CPU. This is achieved by means of a scheduling algorithm, which decides which computing resource will execute each users’ jobs. This task (the scheduling of jobs to computing resources) is done by taking into account th...
متن کاملScheduling in Data Intensive and Network Aware (DIANA) Grid Environments
In Grids scheduling decisions are often made on the basis of jobs being either data or computation intensive: in data intensive situations jobs may be pushed to the data and in computation intensive situations data may be pulled to the jobs. This kind of scheduling, in which there is no consideration of network characteristics, can lead to performance degradation in a Grid environment and may r...
متن کاملNetwork-aware Peer-to-Peer Based Grid Inter-Domain Scheduling
Grid technologies have enabled the aggregation of geographically distributed resources, in the context of a particular application. The network remains an important requirement for any Grid application, as entities involved in a Grid system (such as users, services, and data) need to communicate with each other over a network. The performance of the network must therefore be considered when car...
متن کاملNetwork modeling issues for grid application scheduling
The dominant trend in scientific computing today is the establishment of platforms that span multiple institutions to support applications at unprecedented scales. On most distributed computing platforms a requirement to achieve high performance is the careful scheduling of distributed application components onto the available resources. While scheduling has been an active area of research for ...
