We are interested in making use of Multiclusters to execute parallel
applications. The present work is developed within the M-CISNE project. MCISNE
is a non-dedicated and heterogeneous Multicluster environment which
includes MetaLoRaS, a two-level MetaScheduler that manages the appropriate
job allocation to available resources.
In this paper, we present a new resource-matching model for MetaLoRaS,
which is aimed at mitigating the degraded turnaround time of co-allocated jobs,
caused by the contention on shared inter-cluster links. The model is linear programming
based and considers the availability of computational resources and
the contention of shared inter and intra-cluster links. Its goal is to minimize the
average turnaround time of the parallel applications without disturbing the local
applications excessively and maximize the prediction accuracy.
We also present a parallel job model that takes both computation and communication
characterizations into account. By doing this, greater accuracy is obtained
than in other models only focused on one of these characteristics.
Our preliminary performance results indicate that the linear programming
model for on-line resource matching is efficient in speed and accuracy and can be
successfully applied to co-allocate jobs across different clusters.
