A Min-Min Average Algorithm for Scheduling Transaction-Intensive Grid Workflows
Liu, K., Chen, J., Jin, H. and Yang, Y.
Transaction-intensive grid workflows are attracting
more and more attentions with the prosperity of
e-business and e-government applications. They are
workflows normally with a huge number of relatively
simple concurrent instances, such as business
transactions, whilst some of which may involve
considerable communication overheads. However, there
are almost no specific scheduling algorithms which deal
with such workflows, and existing scheduling
algorithms are not efficient enough for such a scenario if
corresponding adjustments are not conducted. To
address this problem, we propose a novel
Min-Min-Average (MMA) algorithm for efficiently
scheduling transaction-intensive grid workflows
involving considerable communication overheads. The
MMA algorithm is based on the popular Min-Min
algorithm but uses a different strategy for
transaction-intensive grid workflows with the capability
of adapting to the change of network transmission speed
automatically. The comparison based on the simulation
performed on SwinDeW-G, our peer-to-peer based grid
workflow environment, demonstrates that the MMA
algorithm can improve the scheduling performance
significantly over the original Min-Min algorithm when
scheduling transaction-intensive grid workflows with
considerable communication overheads involved. |
