fio 2.1.3-1 (i386 binary) in ubuntu utopic

 fio is a tool that will spawn a number of threads or processes doing a
 particular type of I/O action as specified by the user. fio takes a
 number of global parameters, each inherited by the thread unless
 otherwise parameters given to them overriding that setting is given.
 The typical use of fio is to write a job file matching the I/O load
 one wants to simulate.
