ROMIO

Abstract

ROMIO is optimized for noncontiguous access patterns, which are common in parallel applications. It has an optimized implementation of collective I/O, an important optimization in parallel I/O. ROMIO 1.0.0 includes everything defined in the MPI-2 I/O chapter except file info, shared file pointer functions, split collective data access routines, support for file interoperability, I/O error handling, and I/O error classes. Some limitations of this version are: it works only in homogeneous environments, file size must be less than 2Gbytes.
