In this paper, we describe an implementation of MPI-IO on top of the Direct Access File System (DAFS) standard. The implementation is realized by porting ROMIO on top of DAFS. We ...
MPI is the de-facto standard for message passing in parallel scientific applications. MPI-IO is a part of the MPI-2 specification defining file I/O operations in the MPI world....
Many parallel scientific applications need high-performance I/O. Unfortunately, end-to-end parallel-I/O performance has not been able to keep up with substantial improvements in p...
—Coordinated Checkpoint/Restart (C/R) is a widely deployed strategy to achieve fault-tolerance. However, C/R by itself is not capable enough to meet the demands of upcoming exasc...
