Abstract: As the computing power of supercomputers keeps increasing, the I/O subsystem of these machines has become one of the major bottlenecks of the overall performance. Towards solving this problem, the burst buffer storage architecture has been adopted in the next generation supercomputers. In this paper, we simulated the burst buffer storage architecture on an IBM BlueGene/Q supercomputer using the CODES/ROSS simulation framework to study the potential I/O performance improvement with burst buffers. These results are a stepping stone toward studying this new storage architecture on future dragon-fly network based supercomputers, including resource management covering both storage and job scheduling.
