Abstract

This paper presents our ongoing work on temperature management of many-core real-time systems. Tasks reallocation/migration approach has been proposed as one of the solutions for this problem in which tasks are migrated from a heated core to another less heated core in order to reduce the workload and temperature of the core. However, migrating tasks among cores increases on-chip communication within the processors which in turn increases the temperature of the processor. A naive task migration approach might not provide a good solution for these types of systems. We propose to bound the number of tasks migrations using server-based techniques. Further we propose to improve the admission control in each core by considering the memory usage of the migrating task in addition to the schedulability requirements.
