Abstract
This paper presents the design and implementation of an asynchronous data-staging strategy for file accesses based on ROMIO, the most popular MPI-IO distribution, and ZeptoOS, an open source operating system solution for Blue Gene systems. We describe and evaluate a two-level file write-back implementation and a one-level prefetching solution. The experimental results demonstrate that both solutions achieve high performance through a high degree of overlap between computation, communication, and file I/O. © 2009 Springer Berlin Heidelberg.
