Algorithms in digital signal processing (DSP) impose tight timing constraints that the compiler has to respect while considering the limited capacity of the available register files in a target DSP processor. Traditional code generation methods that schedule spill code to satisfy storage capacity may take many iterations and are usually not capable of satisfying the timing constraints. In this ...

This contribution discusses the application of a fast and sloppy solution of the Eikonal equation – namely the dynamic distance potential field – for the simulation of the flow of a group of pedestrian agents through two bottlenecks with different capacity (width) but identical walking distance toward the destination. It is found that using the method leads to a better distribution of agents on...

The popularity of parallel platforms, such as general purpose graphics processing units (GPGPUs) for large-scale simulations is rapidly increasing, however the I/O bandwidth and storage capacity of these massively-parallel cards remain the major bottle necks. We propose a novel approach for post-processing of simulation data directly on GPGPUs by efficient data size reduction immediately after ...

Considering the advantage of interleave division multiple access (IDMA) technique and the existing technical bottlenecks in satellite systems, IDMA is introduced into satellite communication networks. In multi-beam IDMA satellite systems, combined with unique SINR evolution technology, the system interference value can be accurately estimated, and system capacity can be accurately calculated co...

Tandem queues with finite buffer capacity commonly exist in practical applications. By viewing a tandem queue as an integrated system, an innovative approach has been developed to analyze its performance through the insight from Friedman's reduction method. Fundamental properties of tandem queues with finite buffer capacity are examined. We show that in general system service rate of a dual tan...

Datacenters are at the heart of AI, Industry 4.0 and cloud revolution. A datacenter contains a large number computing nodes hosted in temperature-controlled room. Due to increasing total power density nodes, overall compute capacity is often capped by peak consumption temperature bottlenecks. To preserve homogeneous performance assumption between all complex cooling solution required, but they ...
