• Print the userlist with time log

  19 janvier 2015, par Merlin Sundar

  I have two bash scripts. One which parallelises the other script with accompanied parameters(userlist:10,20,100...),Images :1,2,3..,Image sizes :320x240,640x480...,Virtual machines :1,2,3,4. etc. in a loop and
  the other script that has the executables and a counter for time(this is run in a loop).
  the first script s run on my localhost , after which the directory is changed and the rest is run on the remote server. Technically the entire second script is in the server and begins with the time counter and executables like ffmped, sr.out code. etc.
  Now i want the time log to also have the Userlist printed on it along side(which is so that computation gets easy after running the tests after 8-10 hours. I have written a line in the script but it instead runs the no. of times the user is and then prints time like

  this is 1
  
  0.20
  
  this is 50 
  
  this is 50
  
  this is 50
  
  this is 50
  
  this is 50
  
  this is 50....(50 times) then the time...
  
  2.98
  
  3.49(50 entries

  While all I want is

  This is 1
  
  0.24
  
  This is 50 
  
  2.41
  
  3.43
  
  5.64...(50 entries)
  
  This is 100 
  
  2.40(100 entries)

  How to do it ?

  here are the two codes.
  First code this runs on my end

  #!/bin/bash    
  
  
  
  # Variables are declared:    
  
  
  
  #50 100 200 300 400 500 600 700 800 900 1000    
  
  
  
  #FList=("input/flower1.jpg" "input/flower2.jpg" "input/flower3.jpg" "input/flower4.jpg")    
  
  
  
  #IList=("320X240"           "640X480"           "1280X960"          "1920X1200")    
  
  
  
  NList=(1 10 20)    
  
  
  
  # FList and IList have been aligned exactly below each other so that the variable "index"      
  
  
  
  # takes the order of each file and its corresponding size     
  
  
  
  FList=("input/flower2.jpg")  
  
  
  
  IList=("640X480")         
  
  
  
  SList=(2)           
  
  for (( index=0; $index < ${#FList[@]}; index++ )) do     
  
  
  
      echo "$index"         
  
  
  
      file=${FList[$index]}          
  
  
  
      image_size=${IList[$index]}         
  
  
  
      width=`echo $image_size|cut -d "X" -f1`         
  
  
  
      height=`echo $image_size|cut -d "X" -f2`         
  
  
  
      for scale_factor in ${SList[@]}; do          
  
  
  
              for users in ${NList[@]}; do           
  
  
  
                  echo "V: $VM, " "F: $file, " "S: $scale_factor, " "I: $width $height , " "N: $users"    
  
  
  
              for i in `seq 1 $users` ; do    
  
  
  
                  echo $users    
  
  
  
                  cd ~/Documents/Merlin_testing/     
  
  
  
                  echo This is $users exp >>out_put/Time_log.txt    
  
  
  
                  sh sr_run_once.sh $file $width $height $scale_factor &    
  
  
  
              done    
  
              wait
  
          done # for users            
  
      done # for scale_factor
  
  done # for index
  
  
  
  exit 0

  second script : runs on server

  #!/bin/bash
  
  
  
  output_file=out_put/Time_log.txt
  
  
  
  
  
  START=$(date +%s.%N)
  
  
  
  echo PID=$$
  
  
  
  #argumets : input_file.jpg width height scale_factor  
  
  
  
  ./ffmpeg -i $1  -s $2x$3 -pix_fmt yuv420p in_$$.yuv
  
  
  
      if (($? > 0)); then
  
  
  
  #       echo $? >$output_file
  
  
  
  #       printf '%s\n' 'Failure in first ffmpeg' > $output_file
  
  
  
          exit 1
  
  
  
      fi
  
  
  
  ./OUT_SR.out in_$$.yuv out_sr_$$.yuv  $2  $3 $4
  
  
  
  w=$(($2 * $4));
  
  
  
  h=$(($3 * $4));
  
  
  
  #   if (($? > 0)); then
  
  
  
  #       printf '%s\n' 'Failure in SR.out' >$output_file
  
  
  
  #       exit 1
  
  
  
  #   fi
  
  
  
  ./ffmpeg -s ${w}x${h} -pix_fmt yuv420p -i out_sr_$$.yuv out_put/out_sr_$$.jpg
  
  
  
  
  
  
  
  #   if (($? > 0)); then
  
  
  
  #       printf '%s\n' 'Failure in last ffmpeg' >$output_file
  
  
  
  #               exit 1
  
  
  
  #   fi
  
  
  
  rm -rf out_put/*.yuv
  
  
  
  rm -rf *.yuv
  
  
  
  rm -rf out_put/*.jpg
  
  
  
  END=$(date +%s.%N)
  
  
  
  DIFF=$(echo "$END - $START" | bc)
  
  
  
  echo "this is  $DIFF" | tee -a $output_file
  
  
  
  exit 0
