# RateLimCopyFiles.f uses the iopslimit flowop with the target attribute
# set to the writewholefile flowop to limit the rate to one writewholefile
# operation per event. Without the target attribute set, the limit will
# be one writewholefile OR readwholefile operation per event, so in effect
# it will run at half the rate. Without the target attribute, this workload
# is identical to copyfiles.f. Set the event generator rate by setting
# the $eventrate variable, for instance by typing:
#     set $eventrate=20
# at the go_filebench prompt to get twenty events per second.
#

# $dir - directory for datafiles
# $eventrate - event generator rate (0 == free run)
# $filesize - size of data file
# $iosize - size of each I/O request
# $nfiles - number of files in the fileset
# $nthreads - number of worker threads
