PVFSを用いた計算機間MPI-I/O機能の最適化

概要

MPI (Message Passing Interface) is the de facto standard in parallel computation and many parallel computer vendors have provided own MPI library. Although a vendor-supplied MPI library provides high performance MPI-I/O operations inside a computer, such operations among computers which have different MPI libraries have not been provided yet. To realize seamless MPI-I/O operations among computers, Stampi-I/O was developed. To cope with recent data-intensive parallel computation, a parallel file system named PVFS was supported in Stampi. Although remote MPI-I/O operations to a PVFS file system were realized, its performance was not sufficient for data-intensive computation. To improve throughput of the operations, optimization of a circular buffer in the remote MPI-I/O operations has been carried out, and sufficient performance improvement has been observed.
