Today's Multi-Processor System-on-Chips incorporate advanced communication mechanisms, called Network-on-Chip, to interconnect multiple resources such as processors, memories and accelerators. The detailed evaluation of these communication networks calls for low-level tools that allow detailed performance analysis at the level of the network instead of the analysis at the Processing Elements. We present...
As researchers push for Exascale computing, one of the emerging challenges is system resilience. Unlike fault-tolerance which corrects errors, recent reports suggest that resilient systems will need to continue to make progress on an application despite faults. A first step in developing a resilient system is to have robust, scalable system monitoring. The work described here presents a novel, minimally-invasive...
Although many studies proved that it was possible to embed application servers on a chip with limited resources, security considerations were generally marginalized. Due to their frontal position, application servers are subject to an increasing number of threats. These vulnerabilities are actually ignored in most cases mainly because of cost constraints. This paper introduces the concept of Secure...
System dependability plays an important role in the realization of computer communication infrastructures and the everyday operations and maintenance of computer networks. Increased redundancy is used as a common practice to improve dependability, however in some cases duplication of a networking equipment is not desirable due to high cost or increased system complexity as a result of handling potentially...
With the growing needs for advanced functionalities in modern embedded systems, it is now necessary to integrate multiple processors in the system, preferably on a single chip, to support the required computing complexity. The problem is that such multiprocessor system-on-chip (MPSoC) architecture is very complex and its internal behavior is very difficult to track. An effective tool for profiling...
Embedded computing platforms have long incorporated non-traditional architectures (e.g., FPGAs, ASICs) to combat the diminishing returns of Moore's Law as applied to traditional processors. These specialized architectures can offer higher performance potential in a smaller space, higher power efficiency, and competitive costs. A price is paid, however, in development difficulty in determining functional...
Distributed generation (DG) from wind power becomes increasingly popular worldwide. However, the connection of large wind DGs onto existing radial distribution feeders cause challenges on proper operations of both DGs and their connected feeders. This paper proposes a new Network-enabled Adaptive Protection and Control (NAPC) strategy for properly interfacing wind DGs into distribution grids. The...
