Abstract: This talk will describe the anticipated DOE Exascale initiative, a prospective very large extreme scale supercomputing program being formulated by DOE Office of Science and DOE NNSA. Motivations for the program as well as how the program may proceed will be presented. Anticipated Exascale machine dimensions will be provided as well. An analysis of the costs of providing scalable file systems and I/O for these future very large supercomputers will be examined in detail.
