Therefore, we argue that task adjustment should be always applied when the scheduler determines the per job slots' allocations.
Fig. 16 Detected frontiers for empirical workloads Fig. 17 Detected frontiers for empirical data with task adjustment enabled.
Finally, our proposed task adjustment optimization enhances the performance of the Pareto-based scheduler by minimizing further the workload's makespan.
While for the map/reduce task adjustment, we use a Hill climbing algorithm that gradually increases the number of map and reduce tasks used for the job, keeping the configuration that minimizes its execution time.
Finally, we conducted detailed experiments to illustrate the performance of our tuning adjustment techniques (i.e., Figs. 17, 18, and 19) and the improvements they offer in terms of makespan (i.e., the task adjustment) and budget (i.e., the buffer adjustment technique).
When the Pareto-search algorithm has reserved resources (using either the Slots' or the VMs' allocation technique) for a job it invokes the Task Adjustment component in Fig. 4 to tune the number of map/reduce tasks (i.e., mt j,rt j,∀j∈Jobs) for this job in order to minimize further the job's execution time (i.e., Algorithm 4 in Section 4.3).
For the Iowa Gambling Task, adjustment removed the significant patient control difference, t(40) = 1.07, P = 0.29.
If all tasks, adjustments, and adaptations can be specified ex ante and execution verified ex post, then I do not think a boss is needed for an organization (although a negotiator might be needed).
The contralateral inhibition would be an index of this limb involvement in motor-task adjustment and may be regarded as a tool to maintain a balance of motor output.
In both versions of the task the adjustment increments were reduced by 1/3 after each crossing until reaching the minimum permissible intensity adjustment set by the discrete monitor intensity values.
