A Host Interface Architecture for HPPI

Abstract

Outline: Talk about the Architecture of the host interface for HIPPI and the performance results achieved. The talk includes the following: 1. Very breifly describe the architecture of a Node in the Paragon Supercomputer to point out that an interface is needed to: (a) Handle the requirements of the low-level HIPPI protocol. (b) Transfer data between the input/output channels of HIPPI and the host memory at the aggregate peak rate of 1.6 Gb/s. 2. (a) Describe the architecture of the host interface. (b) Show the data flow between the host memory and the input and output channels (c) Point out software design considerations for high performance. of HIPPI. 3. Discuss the performance results.
