     26 # RateLimCopyFiles.f uses the iopslimit flowop with the target attribute
     27 # set to the writewholefile flowop to limit the rate to one writewholefile
     28 # operation per event. Without the target attribute set, the limit will
     29 # be one writewholefile OR readwholefile operation per event, so in effect
     30 # it will run at half the rate. Without the target attribute, this workload
     31 # is identical to copyfiles.f. Set the event generator rate by setting
     32 # the $eventrate variable, for instance by typing:
     33 #     set $eventrate=20
     34 # at the go_filebench prompt to get twenty events per second.
     35 #
     36 
     37 # $dir - directory for datafiles
     38 # $eventrate - event generator rate (0 == free run)
     39 # $filesize - size of data file
     40 # $iosize - size of each I/O request
     41 # $nfiles - number of files in the fileset
     42 # $nthreads - number of worker threads
