| Outline of Final Research Achievements |
ROMIO is well known as one of the representative MPI-IO implementations, and it provides high performance parallel I/O. However, it can not achieve enough I/O performance when we have multiple processes per node. In this research work, we have introduced topology-aware treatment in layout of processes that play file I/O and data aggregation task associated with the file I/O task in order to improve I/O performance of ROMIO.
Consequently, we have achieved high scalable parallel I/O in ROMIO using the proposed scheme with any kind of process layout.
