Segment file per process for better parallel access
Enable segmenting of file on per-process basis. Break up address space on a per-process basis. They want a group per process. Need mandate from ASCI people. Could do with independent open or flexible parallel. Flexible parallel might fix this too. Another description: "Windowing" on a file, where a group "owns" a section of the file and can operate on that section of the file independently of other parallel processes. It is also suggested that log-based I/O might help.
