hello Kulkarni & Alireza, Thanks for your attentions. tiobench-example.fio will spawn 16 processes, each job consumes 4 processes. But what i want is all things defined in the job description be done in one process. For example, executes below job description --cut-- [global] engine=sync filename=/data/test size=100m [job1] rw=write stonewall [job2] rw=read stonewall [job3] rw=randwrite stonewall [job4] rw=randread stonewall --cut-- This job description can satisfy the demand of sequential execute, but they will be done in 4 different processes. What i want is all things be done in the same process sequentilly. B.R.
