Format PPM

./format.sh

Code:

dt format -n NVPC k

Load metadata

./load.sh

Code:

set $cfgfile, $nodefile,  search file prefix($prefix).
echo 'Greppy system is starting.....'
tr '\n' from the $nodefile

function get_basic_info:
    get vpcs,space,ip,slot,filename, nf(how many parts one line divided by space) info from $nodefile, all vars are array var.

function make_link:
parameter: $file need to search
    if [ ! -f $file on $ip ] :
          echo '$file not on $ip" and exit
    else:
          make links with $file into  thinker stdin dir.

function gain_config() :
printf $space, $filesize, $dejavusize into $cfgfile

totalline = len of $nodefile

function gen_config()
mv vpc.$num and nrcs.$num to thinker runtime dir.

for i in range(0,totalline):
    get_basic_info()
    $host[i] = $ip
    if [ $nf -eq 2 ]  ##means file need to search
      make_link
      gain_config
   else
      print $space, 0, 0, 'n' to $cfgfile
      
gen_config()
call make datacfg to run size prog
call make read to run read prog

Start service

./start.sh

Code:

trap ctrl_c

if type ctrl_c; then
    echo "You type ctrl_c to terminate program"
    kill DT
    clean all object files and exit

if the 1st parameter  == 'nohup'; then
    nohup do_start &
else
    do_start

function do_start() {
    make run
}

Stop service

./stop.sh

Code:

dt slay -n NVPC k

Show status

./status.h

Code:

dexer --ips=$ips "ps aux" | grep -E 'vpc|nrc|scheduler|mem_home|atpd|auntie|ncat' | grep 'sage' | grep -v 'dexer' | grep -v 'grep'
