This is DAG job submiting example. For demonstration use attached file.

DAG.zip

1.Extract file with:

[ngrkic@ui ~]$ unzip DAG.zip

2.Enter directory single with:

[ngrkic@ui ~]$ cd DAG

3.List directory:

[ngrkic@ui DAG]$ ll

-rwxr-xr-x  1 ngrkic ngrkic   92 Oct  1 15:54 job.sh

[
Type = "dag";
InputSandbox = {"job.sh"};

Nodes = [
 nodeA = [
           Description = [
            JobType = "Normal";
            Executable = "job.sh";
            Arguments = "A";
            StdOutput = "std.out";

            InputSandbox = {root.InputSandbox[0]};
            OutputSandbox = {"std.out","std.err"};
           ];
         ];
 nodeB = [
           Description = [
            JobType = "Normal";
            Executable = "job.sh";
            Arguments = "B";

Dependencies = {
                {nodeA,nodeB},{nodeA,nodeC},{{nodeB,nodeC},nodeD}
};
]

This is content of file job.sh

#!/bin/bash 

echo "Job $1 - `date` - BEGIN"
hostname
sleep 100
echo "Job $1 - `date` - END"

In this case job is splited on 4 independent jobs.First C job will be executed, then B job, and finaly A and D

4.Creating VOMS proxy:

[ngrkic@ui DAG]$ voms-proxy-init -voms aegis
Cannot find file or dir: /home/ngrkic/.glite/vomses
Enter GRID pass phrase:
Your identity: /C=RS/O=AEGIS/OU=Institute of Physics Belgrade/CN=Nikola Grkic
Creating temporary proxy ......................... Done
Contacting  voms.ipb.ac.rs:15001 [/C=RS/O=AEGIS/OU=Institute of Physics Belgrade/CN=host/voms.ipb.ac.rs] "aegis" Done
Creating proxy ..................................................... Done
Your proxy is valid until Fri Oct  2 01:11:00 2009


Now we are ready to submit job.


5.Submiting DAG job:

[ngrkic@ui DAG]$ glite-wms-job-submit -a jobDAG.jdl 
Connecting to the service https://wms-aegis.ipb.ac.rs:7443/glite_wms_wmproxy_server


====================== glite-wms-job-submit Success ======================

The job has been successfully submitted to the WMProxy
Your job identifier is:

https://wms-aegis.ipb.ac.rs:9000/O3Bxi2I9DoE2Lltmcoe0eQ

==========================================================================


Copy the job ID.Job is running now, and it should finish in few moments...


6.Requesting Job status:

[ngrkic@ui DAG]$ glite-wms-job-status https://wms-aegis.ipb.ac.rs:9000/O3Bxi2I9DoE2Lltmcoe0eQ

7.Requesting Job output:

[ngrkic@ui DAG]$ glite-wms-job-output --dir /home/ngrkic/test https://wms-aegis.ipb.ac.rs:9000/O3Bxi2I9DoE2Lltmcoe0eQ
Connecting to the service https://wms-aegis.ipb.ac.rs:7443/glite_wms_wmproxy_server

================================================================================

			JOB GET OUTPUT OUTCOME

Output sandbox files for the DAG/Collection :
https://wms-aegis.ipb.ac.rs:9000/O3Bxi2I9DoE2Lltmcoe0eQ
have been successfully retrieved and stored in the directory:
/home/ngrkic/test

================================================================================


8.Go to test directory and see output with commands:

[ngrkic@ui ~]$ cd 
[ngrkic@ui ~]$ cd test
[ngrkic@ui test]$ ll

drwxr-xr-x  2 ngrkic ngrkic 4096 Oct  1 17:31 nodeA
drwxr-xr-x  2 ngrkic ngrkic 4096 Oct  1 17:31 nodeB
drwxr-xr-x  2 ngrkic ngrkic 4096 Oct  1 17:31 nodeC
drwxr-xr-x  2 ngrkic ngrkic 4096 Oct  1 17:31 nodeD
[ngrkic@ui test]$ cd nodeA
[ngrkic@ui nodeA]$ ll
-rw-rw-r--  1 ngrkic ngrkic   0 Oct 12 17:31 std.err
-rw-rw-r--  1 ngrkic ngrkic 112 Oct 12 17:31 std.out

[ngrkic@ui nodeA]$ cat std.out 
Job A - Thu Oct 1 17:14:14 CEST 2009 - BEGIN
grid10.elfak.ni.ac.rs
Job A - Thu Oct 1 17:14:54 CEST 2009 - END

For each node there is simular output.
