Read ahead / prefetching
...elf on prefetching/readahead algorithm for
Lustre''s read. For a starter I only have two simple questions.
1 - Does Lustre detect linear or random I/O pattern or it always triggers
readahead?
2 - If readahead is triggered, how many pages are read in addition to what
is necessary?
Thanks,
Arifa.
