Abstract

Summary A flexible intermediate library named Stampi realizes seamless MPI operations on interconnected parallel computers. In message transfer of Stampi, a vendor-supplied MPI library and TCP sockets are used selectively among MPI processes. Its router process mechanism hides a complex network configuration in message transfer among computers. Besides, dynamic process creation and MPI-I/O are also available. With the help of its flexible communication mechanism, users can execute MPI functions without awareness of underlying communication and I/O mechanisms. To realize distributed I/O operations with high performance, a Parallel Virtual File System (PVFS) has been introduced in the MPI-I/O mechanism of Stampi. Collective MPI-I/O functions have been evaluated and sufficient performance has been achieved.
