High Utilization: the Wrong Thing to Measure?
In GridToday, Univa UD's Rich Wellner questions the merits of measuring utilization rates in cluster or grid. Instead, says Wellner, a factor like latency has far more impact on an organization's effectiveness and core business missions:
"If your clusters are running at 80 percent, that means that you have a lot of periods when work is being queued up and waiting. Think about the utilization pattern of your cluster. Almost every cluster out there is in one of two patterns: they are busy starting at nine in the morning when people start running work and the queue empties overnight, or they are busy starting at three in the afternoon when people have finished thinking about what they need to run overnight and the queue empties the next morning."
