چکیده
In this paper we outline the Adaptive Resource Allocation Protocol (ARAP) as an improved resource synchronization algorithm for hierarchically scheduled real-time systems. ARAP exploits knowledge about task utilization, using a proportionalintegral-derivative (PID) controller, to estimate required resource bandwidth and improve scheduling decisions. Our analysis and experiments with RTSIM show that ARAP provides better temporal isolation and resource utilization during periods of transient overload compared to state-of-the-art resource synchronization algorithms. Implemented as part of VxWorks, the results are confirmed using an avionic system, for which ARAP substantially reduced the number of hard real-time deadline misses.

In this talk we will present recent developments in the design and analysis of numerical homogenization methods. Numerical methods for linear and nonlinear partial differential equations that combine multiscale methods with reduced order modeling techniques such as the reduced basis method will be discussed. The talk is based upon a series of joint works with various collaborators[1,2,3,4,5]. [...
