As the number of processor cores and sockets on HPC compute nodes increase and
systems expose more hierarchical non-uniform memory access (NUMA) architectures …

Embedded systems in safety-critical domains, such as avionics, space, automotive, health-
care etc., require hard real-time and reliable application execution. As applications are …

In this Chapter, we focus on the concept of performance variation in digital systems and
discuss its sources, mainly the interdependence with certain phenomena manifesting in the …

In recent years, dependability of digital systems has been threatened partly due to highly
dynamic workloads, user input data, environment and hardware imperfections known as …

Modern computing systems strive to provide ever increasing performance levels despite
increasingly strict system-wide optimization objectives. This is a vast problem that spans …

Complexity of modern supercomputers is rising steadily, especially with the introduction of
heterogenous and distributed computing resources. This complexity also affects the …
