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:

hello.c

#include <stdio.h>

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


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 hello.SE]$ ll hello.SE

4. See content of files

[ngrkic@ui hello.SE]$ cat hello.jdl 
Executable = "run.sh";
Arguments = "";
StdOutput = "std.out";
StdError = "std.err";
InputSandbox = {"run.sh"};
OutputSandbox = {"std.out", "std.err"};
Requirements =  RegExp("ce64.ipb.ac.rs*",other.GlueCEUniqueID);
[ngrkic@ui hello.SE]$ cat run.sh 

#Downloading source code from SE
lcg-cp lfn:/grid/aegis/power/src.tgz 'src.tgz'

#Extract code 
tar xvzf src.tgz

#Compile C file

gcc hello.c -o hello

#Execute hello program

./hello >> output

#Make tgz arhive of output 
tar cvzf output.tgz output

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


5. Creating VOMS proxy:

[ngrkic@ui hello.SE]$ voms-proxy-init -voms aegis
