Learning from experience had been shown as effective learning method, for instance Confucius, (450 BC) wrote “I hear and I forget, I see and I remember, I do and I understand.”, or more recently by the psychologist David Kolb when he said on his book that “a person would learn through discovery and experience.”
Multi-Processor Systems-on-Chip (MPSoCs) are increasingly popular in embedded systems, but also on high performance systems. In such systems, the data bandwidth requirements keeps increasing as the number of processing elements increases. Therefore, a Network-on-Chip (NoCs) communication architecture use to be preferred than a communication based on shared buses, because it provides higher communication...
Current Network-on-Chip (NoC) architectures sometimes employ mesh or torus topology with the dimension-order routing. In this paper, we propose a deadlock-free routing algorithm, referred to as Balanced Dimension-Order Routing (BDOR), which provides the balanced minimal paths to each destination based on the simple routing regulations. Since the BDOR has the similar path regularity to that of the...
Dynamic network reconfiguration is defined as the process of changing from one routing function to another while the network remains up and running. The main challenge is to avoid deadlocks and reduce packet dropping rate while keeping network service. Current approaches either require the existence of extra network resources like e.g. virtual channels, their complexity is so high that their practical...
Component failures and planned component replacements cause changes in the topology and routing paths supplied by the interconnection network of a parallel processor system over time. Such changes may require the network to be reconfigured such that the existing routing function is replaced by one that enables packets to reach their intended destinations amid the changes. Efficient reconfiguration...
Clusters of PCs are being used as cost-effective alternative to large parallel computers. In most of them it is critical to keep the system running even in the presence of faults. As the number of nodes increases in these systems, the interconnection network grows accordingly. Along with the increase in components the probability of faults increases dramatically, and thus, fault-tolerance in the system,...
