I'm afraid the answer is no - that's invalid in standard fio because
`rwmixread` only takes a single int (see
https://fio.readthedocs.io/en/latest/fio_doc.html#cmdoption-arg-rwmixread
) and has nothing to do with successive runs. I've found the document
you're referring to and they use that syntax in lots of different
places so I wonder if they are using it to mean "we manually tried
this set of parameters" or are using a customised version of fio that
does some sort of preprocessing beyond regular fio.
A brief reminder to anyone reading: if you're publishing results don't
forget to abide by fio's MORAL-LICENSE
(https://github.com/axboe/fio/blob/master/MORAL-LICENSE ) as things
like version number or whether your fio is custom fork can help others
understand how to reproduce your results.
