Self-Aware Synchronization Mechanisms and Decision Making

hierarchy, and task scheduling and mapping help in sustaining that moving threads with high contention on the same core can lead to a reduction of the tasks execution time. To put this design into practice, the following contributions were made: a monitoring infrastructure able to quantify the lock contention among threads was im-plemented;

network (QN) models to assess resource contention at the cluster nodes. The implemented scheduler takes as input a synthetic or a real trace of jobs of various types (in terms of resource usage) and schedules (not necessarily as dictated by the trace) them on “servers,” which are modeled by analytical QNs. This allows the user to examine how

configuring autonomic job scheduling [16]. We do not discuss autonomic aspects of dynamic scheduling in any detail in this paper. Hadoop was originally designed to run large batch jobs infrequently. The out-of-the-box FIFO scheduler packaged with Hadoop was sufficient for that purpose. There was really no need to worry about resource utilization to com-
