Abstract

Describes input/output (I/O) system software that makes I/O on a massively parallel computer as scalable as computing. The analysis is centered around mapping functions, which form an intellectual framework from which to understand parallel I/O. The I/O system not only provides the raw capability of doing parallel I/O, but is also convenient to use and compatible with Unix. These features are in release 3 of the nCUBE system software. This system will transfer data in parallel between scalable programs and/or I/O devices with any number of units. The first test demonstrated heterogeneous programming, or parallel pipes. Results are provided for a parallel pipe using various mapping combinations. The second test demonstrated I/O between parallel programs and secondary storage. Performance figures are given.<>
