Such systems need to adapt task scheduling and mapping to optimise for performance and energy under varying workloads and, increasingly important, for thermal and fault management and are thus relevant targets for self-aware computing. In this chapter, we take up the generic reference architecture for designing self-aware and self-expressive computing systems and refine it for heterogeneous multi-cores. We present ReconOS, an architecture, programming model and execution environment for heterogeneous multi-cores, and show how the components of the reference architecture can be implemented on top of ReconOS. In particular, the unique feature of dynamic partial reconfiguration supports self-expression through starting and terminating reconfigurable hardware cores. We detail a case study that runs two applications on an architecture with one CPU and 12 reconfigurable hardware cores and present self-expression strategies for adapting under performance, temperature and even conflicting constraints. The case study demonstrates that the reference architecture as a model for self-aware computing is highly useful as it allows us to structure and simplify the design process, which will be essential for designing complex future compute nodes. Furthermore, ReconOS is used as a base technology for flexible protocol stacks in Chapter 10, an approach for self-aware computing at the networking level."}],"doi":"10.1007/978-3-319-39675-0_8","date_updated":"2023-09-26T13:27:44Z","has_accepted_license":"1","quality_controlled":"1","language":[{"iso":"eng"}],"title":"Self-aware Compute Nodes","project":[{"grant_number":"160364472","name":"SFB 901","_id":"1"},{"grant_number":"160364472","name":"SFB 901 - Subprojekt C2","_id":"14"},{"name":"SFB 901 - Project Area C","_id":"4"},{"grant_number":"257906","name":"Engineering Proprioception in Computing Systems","_id":"31"}],"department":[{"_id":"518"},{"_id":"27"},{"_id":"78"}],"user_id":"15278","publisher":"Springer International Publishing","citation":{"mla":"Agne, Andreas, et al. “Self-Aware Compute Nodes.” <i>Self-Aware Computing Systems</i>, Springer International Publishing, 2016, pp. 145–65, doi:<a href=\"https://doi.org/10.1007/978-3-319-39675-0_8\">10.1007/978-3-319-39675-0_8</a>.","ieee":"A.
