MPI-Based Adaptive Task Migration Support on the HS-Scale System

Scalability of architecture, programming model and task control management will be a major challenge for future VLSI systems. In this context, homogeneous MPSOC is a seducing approach as it is intrinsically scalable. HS-Scale is a contribution in this domain and was already published in [1,2]. In this article, we present an original MPI-based adaptive task migration support for the HS-Scale system. Our previous communication API was modified in order to be MPI compliant. In order to enable task migration without any MMU, a Position Independent Code compilation technique is implemented. The self-adaptability is based on monitoring information collected at run-time by each processing element (PE). Each PE is endowed with the same decisional capability insuring the scalability of the solution. A MJPEG case study validated on a multi-FPGA prototyping platform is presented. The observation of the dynamic behavior of HS-Scale shows that the system is able to find itself a stable task placem...
