This is simple single job submitting example with data management. In this case, WN will download source code and executing script from SE and after successful ending of job, result will be uploaded on SE.


Content of uploaded files:


#include <stdio.h>

int main()
 printf ("hello world!!\n");
 return 0;

#Compile C file

gcc hello.c -o hello

#Execute hello program


1. Extract files

[ngrkic@ui jobovi]$ tar xvzf hello.SE.tgz

2. Enter directory hello.SE

[ngrkic@ui jobovi]$ cd hello.SE

3. List directory

[ngrkic@ui jobovi]$ ll hello.SE

4. See content of files

[ngrkic@ui hello.SE]$ cat hello.jdl 
Executable = "";
Arguments = "";
StdOutput = "std.out";
StdError = "std.err";
InputSandbox = {""};
OutputSandbox = {"std.out", "std.err"};
Requirements =  RegExp("*",other.GlueCEUniqueID);
[ngrkic@ui hello.SE]$ cat 
#Downloading source code from SE
lcg-cp lfn:/grid/aegis/nikola/hello.SE/hello.c 'pwd'

#Downloading script that compiles source code and execute program
lcg-cp lfn:/grid/aegis/nikola/hello.SE/ 'pwd'

#runing compile & execute script

#Uploads output to SE
lcg-cr -l lfn:/grid/aegis/nikola/hello.SE/std.out file:`pwd`/std.out
