How to measure competition? The role of price dispersion in B2B supply markets

Since the formation of close relationships with suppliers requires a considerable amount of resources, the capacities for such relationships are limited. Thus, recently, research points into the direction that it might not be conducive to unconditionally engage in strategic buyer-supplier alliances. Specifically, in those cases where there is a vivid competition within the supply market, it might not be necessary to cooperate closely. However, a convenient measurement method for competition has been missing in the literature so far. Accordingly, this conceptual paper translates insights from the field of economics for an application in purchasing and supply management. It is recommended to evaluate the product price dispersion of supplier quotations in order to assess the intensity of competition in supply markets. As a consequence, this conceptual paper paves the way for future research on competition between suppliers. For managers, the proposed method could support the development of efficient purchasing strategies

A High-performance, Energy-efficient Modular DMA Engine Architecture

Data transfers are essential in today's computing systems as latency and complex memory access patterns are increasingly challenging to manage. Direct memory access engines (DMAEs) are critically needed to transfer data independently of the processing elements, hiding latency and achieving high throughput even for complex access patterns to high-latency memory. With the prevalence of heterogeneous systems, DMAEs must operate efficiently in increasingly diverse environments. This work proposes a modular and highly configurable open-source DMAE architecture called intelligent DMA (iDMA), split into three parts that can be composed and customized independently. The front-end implements the control plane binding to the surrounding system. The mid-end accelerates complex data transfer patterns such as multi-dimensional transfers, scattering, or gathering. The back-end interfaces with the on-chip communication fabric (data plane). We assess the efficiency of iDMA in various instantiations: In high-performance systems, we achieve speedups of up to 15.8x with only 1 % additional area compared to a base system without a DMAE. We achieve an area reduction of 10 % while improving ML inference performance by 23 % in ultra-low-energy edge AI systems over an existing DMAE solution. We provide area, timing, latency, and performance characterization to guide its instantiation in various systems.Comment: 14 pages, 14 figures, accepted by an IEEE journal for publicatio
