This project began in 1999 after completion of a feasibility study. The NERSC HPSS Storage System used HIPPI IPI3 capable disk and the HIPPI IPI-3 driver was not available on newer Cray computers (J90's and T3E). The purpose of the project was to develop a user-level implementation of the third party HIPPI IPI-3 capability, using the standard HIPPI driver. The Protocol is implemented in a portable library which can be linked with HPSS client applications such as HSI & PFTP.
The following slides are a presentation of the NERSC 3rd Party IPI-3 Project for HPSS/hsi. This work was done by Mike Gleicher for NERSC.
A brief document summarizing the modifications that were made to the HPSS source code in support of this project is available.
Michael Gleicher's presentation is available as a PowerPoint file.
