It has two filesets, one of videos 26 # being actively served, and one of videos availabe but currently inactive 27 # (passive). However, one thread, vidwriter, is writing new videos to replace 28 # no longer viewed videos in the passive set. Meanwhile $nthreads threads are 29 # serving up videos from the activevids fileset. If the desired rate is R mb/s, 30 # and $nthreads is set to T, then set the $srvbwrate to R * T to get the 31 # desired rate per video stream. The video replacement rate of one video 32 # file per replacement interval, is set by $repintval which defaults to 33 # 10 seconds. Thus the write bandwidth will be set as $filesize/$repintval. 34 35 set $dir=/tmp 36 set $eventrate=96 37 set $filesize=10g 38 set $nthreads=48 39 set $numactivevids=32 40 set $numpassivevids=194 41 set $reuseit=false 42 set $readiosize=256k 43 set $writeiosize=1m 44 # 45 set $passvidsname=passivevids 46 set $actvidsname=activevids 47 # 48 set $repintval=10 49 50 eventgen rate=$eventrate 51 52 define fileset name=$actvidsname,path=$dir,size=$filesize,entries=$numactivevids,dirwidth=4,prealloc,paralloc,reuse=$reuseit 53 define fileset name=$passvidsname,path=$dir,size=$filesize,entries=$numpassivevids,dirwidth=20,prealloc=50,paralloc,reuse=$reuseit 54 55 define process name=vidwriter,instances=1 56 { 57 thread name=vidwriter,memsize=10m,instances=1 58 { 59 flowop deletefile name=vidremover,filesetname=$passvidsname 60 flowop createfile name=wrtopen,filesetname=$passvidsname,fd=1 61 flowop writewholefile name=newvid,iosize=$writeiosize,fd=1,srcfd=1 62 flowop closefile name=wrtclose, fd=1 63 flowop delay name=replaceinterval, value=$repintval 64 } 65 } 66 67 define process name=vidreaders,instances=1 68 { 69 thread name=vidreaders,memsize=10m,instances=$nthreads 70 { 71 flowop read name=vidreader,filesetname=$actvidsname,iosize=$readiosize 72 flowop bwlimit name=serverlimit, target=vidreader 73 } 74 } 75 76 echo "Video Server Version 1.1 personality successfully loaded" 77 usage "Usage: set \$dir=<dir> defaults to $dir" 78 usage " set \$eventrate=<value> defaults to $eventrate" 79 usage " set \$filesize=<size> defaults to $filesize" 80 usage " set \$nthreads=<value> defaults to $nthreads" 81 usage " set \$writeiosize=<value> defaults to $writeiosize" 82 usage " set \$readiosize=<value> defaults to $readiosize" 83 usage " set \$numactivevids=<value> defaults to $numactivevids" 84 usage " set \$numpassivevids=<value> defaults to $numpassivevids" 85 usage " " 86 usage " run runtime (e.g. run 60)" 87
