CO>operating system is layered on the top of the native OS

When a graph is executed it has to be deployed in host settings and connection method like rexec, telnet, rsh, rlogin This is what the graph interacts with the co>op.

hi sunitha

when ever you press Run button on your GDE,the GDE genarates a script

and the genarated script will be transfered to your host which is specified in to your GDE run settings. then the Co>operating system interprets this script and executes the script on different mechins(if required) as a sub process(threads),after compleation of each sub process,these sub_processes will  return status code to main process this main process in tern returns error or sucess code of the job to GDE

hope this helps you

cheers

when you run gde the co-op sys converts the gde into local langg of unix.

co-op sys acts like interpretator to operating system.
