Hello, On our computing grid, we are running Son of Grid Engine version 8.1.8.
I'm doing some statistics on our grid usage. About IO usage (field 39), man 5 accounting says: "The amount of data transferred in input/output operations in GB (if available, otherwise 0). On Linux, this is summed over calls to read(2), pread(2), write(2), and pwrite(2); thus it includes i/o via cache, and may not reflect data actually written to filing system." Our scientists do mainly machine learning, video, audio recognition and such processing. I'd like to have an idea of how our IO infrastructure is used by the jobs. My concern is about separating what is local cache/tmp IO traffic and "real" disk IO traffic. Has someone defined something like a "typical usage ratio" between cache and data transfer ?
