The ever-increasing performance and power demand of HPC systems requires sophisticated approaches that improve energy-efficient job execution. Targeted goals such as the 20-MW limit for an exascale system, set by the Department of Energy (DoE), are not achievable with advances at hardware level only. Instead, it is inevitable to establish new concepts at system-software level. We propose a system...
Sensor networks have successfully been used for wildlife monitoring and tracking of different species. When it comes to small animals such as smaller birds, mammals, or even insects, the current approach is to use extremely lightweight RF tags located using radio telemetry. A new quantum leap in technology is needed to overcome this limitation and enable new ways to observe larger numbers of small...
Energy has emerged to be the most important resource for computing systems. Despite the exceptional importance of energy, reducing its demand at application and system level remains a challenging task for programmers and engineers. This is aggravated by the fact that traditional energy-saving approaches are not only error-prone but even lead to adverse consequences (i.e. increased energy consumption)...
