Title:

Lightweight task migration in multi-tiled architecture - Communication consistency

Abstract:

Multi-tiled architecture has come into play as a feasible and efficient architectural solution for MPSoC. Each tile contains at least one processor, one memory and associated peripherals with distributed network devices; the later provide necessary primitives for inter-tile communications on such a fully distributed memory architecture.
We present a solution for a lightweight task migration on such architectures. Task code replication is used wisely to achieve migration and to be deployed on simple embedded operating systems. We target data flow applications with a thorough emphasis on solving communication inconsistency issues. Applications on multi-tile architectures highlight the effectiveness of our approach. Beside the fact that this solution enables the system to remap its task at runtime, it indeed contributes to increasing reliability of the system by enabling responsiveness to temperature increase, or workload imbalance.
