Dynamic Multi-Resource Load Balancing in Parallel Database Systems
Parallel database systems have to support the effective parallelization of complex queries in multi-user mode, i.e. in combination with inter-query/inter-transaction parallelism. For this purpose, dynamic scheduling and load balancing strategies are necessary that consider the current system state for determining the degree of intra-query parallelism and for selecting the processors for executi...
متن کاملDynamic Load Balancing in Parallel Database Systems
Parallel database systems have to support both inter-transaction as well as intra-transaction parallelism. Inter-transaction parallelism (multi-user mode) is required to achieve high throughput, in particular for OLTP transactions, and sufficient cost-effectiveness. Intratransaction parallelism is a prerequisite for reducing the response time of complex and dataintensive transactions (queries)....

متن کاملDynamic Load Balancing for Parallel
Adaptive mesh reenement is a key problem in large-scale numerical calculations. The need of adaptive mesh reenement could introduce load imbalance among processors, where the load measures the amount of work required by reenement itself as well as by numerical calculations thereafter. We present a dynamic load balancing algorithm to ensure that the work load are balanced while the communication...
متن کاملDynamic Load Balancing in Hierarchical Parallel Database Systems
We consider the execution of multi-join queries in a hierarchical parallel system, i.e., a shared-nothing system whose nodes are shared-memory multiprocessors. In this context, load balancing must be addressed at two levels, locally among the processors of each shared-memory node and globally among all nodes. In this paper, we propose a dynamic execution model that maximizes local load balancin...
