Case studies of data traffic management on a high-performance computing system based on multi-DSPs and Serial RapidIO interconnect

A massively parallel machine based on Serial RapidIO (SRIO) interconnect is presented in this paper. The proposed machine consists of multi digital signal processors (multi-DSPs) and multi-cores in one DSP. A core is the basic processing element and the SRIO is the inter-processors communication bus. This paper presents several cases studies of traffic management in the proposed parallel machine in order to make optimal choices and to maximize transfer performance by managing and by controlling the data flow. Experimental results of each case study of traffic management and flow control is presented.
