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.

- TargetEnvironment
- ROMIO 1.0.1 runs on the following machines: IBM SP;
Intel Paragon; HP Exemplar; SGI Origin2000; NEC SX-4;
other symmetric multiprocessors from HP, SGI, DEC,
and IBM; and networks of workstations (Sun, SGI, HP,
IBM, DEC, Linux, and FreeBSD). Supported file systems
are IBM PIOFS, Intel PFS, HP/Convex HFS, SGI XFS, NEC
SFS, NFS, and any Unix file system (UFS). ROMIO 1.0.1
works with and is included in MPICH 1.1.1 and in HP
MPI 1.4. It also works with SGI MPI 3.1 and higher
and with NEC MPI.
