It has two filesets, one of videos # being actively served, and one of videos availabe but currently inactive # (passive). However, one thread, vidwriter, is writing new videos to replace # no longer viewed videos in the passive set. Meanwhile $nthreads threads are # serving up videos from the activevids fileset. If the desired rate is R mb/s, # and $nthreads is set to T, then set the $srvbwrate to R * T to get the # desired rate per video stream. The video replacement rate of one video # file per replacement interval, is set by $repintval which defaults to # 10 seconds. Thus the write bandwidth will be set as $filesize/$repintval. set $dir=/tmp set $eventrate=96 set $filesize=10g set $nthreads=48 set $numactivevids=32 set $numpassivevids=194 set $reuseit=false set $readiosize=256k set $writeiosize=1m # set $passvidsname=passivevids set $actvidsname=activevids # set $repintval=10 eventgen rate=$eventrate define fileset name=$actvidsname,path=$dir,size=$filesize,entries=$numactivevids,dirwidth=4,prealloc,paralloc,reuse=$reuseit define fileset name=$passvidsname,path=$dir,size=$filesize,entries=$numpassivevids,dirwidth=20,prealloc=50,paralloc,reuse=$reuseit define process name=vidwriter,instances=1 { thread name=vidwriter,memsize=10m,instances=1 { flowop deletefile name=vidremover,filesetname=$passvidsname flowop createfile name=wrtopen,filesetname=$passvidsname,fd=1 flowop writewholefile name=newvid,iosize=$writeiosize,fd=1,srcfd=1 flowop closefile name=wrtclose, fd=1 flowop delay name=replaceinterval, value=$repintval } } define process name=vidreaders,instances=1 { thread name=vidreaders,memsize=10m,instances=$nthreads { flowop read name=vidreader,filesetname=$actvidsname,iosize=$readiosize flowop bwlimit name=serverlimit, target=vidreader } } echo "Video Server Version 1.1 personality successfully loaded" usage "Usage: set \$dir=<dir> defaults to $dir" usage " set \$eventrate=<value> defaults to $eventrate" usage " set \$filesize=<size> defaults to $filesize" usage " set \$nthreads=<value> defaults to $nthreads" usage " set \$writeiosize=<value> defaults to $writeiosize" usage " set \$readiosize=<value> defaults to $readiosize" usage " set \$numactivevids=<value> defaults to $numactivevids" usage " set \$numpassivevids=<value> defaults to $numpassivevids" usage " " usage " run runtime (e.g. run 60)"
