Abstract
In this paper we present the MPI-IO Interface kernel in the Vienna Parallel Input Output System (ViPIOS), which is a client-server based parallel I/O system. Compared to the already existing parallel I/O systems and libraries the concept of an independent distributed server promises to greatly enhance the usability and acceptance of the I/O system as well as the portability of client applications. The programmer of a client application does not have to deal with details like file layout on disk, sharing of filepointers etc. Instead high level MPI-IO requests may be issued and the server is expected to perform them in a (near) optimal way.
ViPIOS is based on MPI and is targeted (but not restricted) to MPP's using the SPMD paradigm. We describe the current system architecture in general and give a detailed overview of MPI-related design considerations.
This work was carried out as part of the research project ”Language, Compiler, and Advanced Data Structure Support for Parallel I/O Operations” supported by the Austrian Science Foundation (FWF Grant P11006-MAT)
