Scalable Coherent Interface

Recently, connecting thousands of processors via interconnection networks based on multiple (hierarchical) rings has an increased interest. This is due to the large acceptance and success of the Scalable Coherent Interface (SCI) technology. The inherently weak behavior of ring architecture has led interconnection designers to consider various choices to improve the overall network reliability. An interesting choice is to use braided rings instead of the single (basic) rings in the hierarchy. In this paper, we present new formulas for computing K-processor reliability of SCI ring-based hierarchical networks in the context of large-scale multiprocessor systems. The derived formulas are general and applicable to any given systems size consisting of an arbitrary number of levels. The reliability of hierarchical systems based on the basic and braided rings is evaluated and analyzed using the derived formulas. The results show that hierarchical systems based on braided rings significantly improve the reliability of hierarchies constructed of basic rings. The results are general and not limited to systems of SCI rings; the analysis is valid for any type of rings architecture such as token and slotted rings.

Scalable Coherent Interface

Abstract Multimedia technology has become widely available and it has tremendous potential. As computers getting faster every day, multimedia applications are reaching new ground constantly. However, a fundamental problem of multimedia systems is the interprocessor/intermachine communication speed. In this paper, we introduce a platform based on the Scalable Coherent Interface (SCI, ANSI/IEEE std 1596). The system can be physically distributed but logically closely coupled. All processors/machines in an SCI system shared physical memory and cache coherence is maintained even among remote processors. The interprocessor communication bandwidth can be as high as 1 Gbyte/sec. We will discuss the features of SCI-based systems when multimedia application is considered.
