MADCAPP: measurement and analysis of high-level communications of asynchronous distributed algorithms on parallel processors

Article Abstract:

The issue of correctness of complex asynchronous distributed algorithms implemented on loosely coupled parallel processor systems is difficult to address given the lack of effective debugging tools. In such systems, messages propagate asynchronously over physical connections and precise knowledge of the state of every message in the system at any instant of time is difficult to obtain. For a particular class of asynchronous distributed algorithms (1,2,5) that may be characterized by independent models that execute asynchronously on the processors and interact with one another only through explicit messages, the following reasoning applies. Information on the flow and content of messages and the activity of the processors is significant towards understanding the functional correctness of the implementation.

Selection Criteria and Performance Evaluation Methods for Peripheral Array Processors

Article Abstract:

Peripheral array processors are a class of digital computing devices designed to serve as peripherals for large mainframe, minicomputers, and microcomputers. Through extensive parallelism and pipelining, peripheral array processors greatly enhance the capabilities of the host computer to process numerical data at a very high speed, particularly in simulation and signal processing applications. An overview of the peripheral array processing field is presented in this paper followed by a discussion of five different approaches to the performance specification and evaluation of these devices.
