Recently, Multicluster environments have become more important in
the high-performance computing world. However, less attention has been paid
to non-dedicated Multiclusters. We are developing MetaLoRaS, an efficient twolevel
MetaScheduler for non-dedicated environments, which assigns PVM and
MPI applications according to an estimation of the turnaround time in each particular
cluster.
The main MetaScheduler goal is to minimize the average job turnaround time
in a non-dedicated environment. The efficiency of MetaLoRaS depends on the
prediction accuracy of the system and its ability to take decisions according to
changes in local workload.
In this paper we present different Metascheduling techniques that take the
dynamics of the local workload into account and compare their effects on system
performance. We evaluate the prediction accuracy in relation to the low-level
queues sizes. Finally, we analyze the relationship between prediction accuracy
and system performance.
