Job command line tools

In order to submit a job, it should be described in a form of JDL. An example JDL for a simple job is presented below:

Executable = "/bin/cp";
Arguments = "my.file my.copy";
InputSandbox = {"my.file"};
StdOutput = "std.out";
StdError = "std.err";
OutputSandbox = {"std.out","std.err","my.copy"};
CPUTime = 10;

This job will take a local file “my.file”, put it into the Input Sandbox and then copy it to the “my.copy” file on the Grid. In the Output Sandbox the new copy will be returned together with the job standard output and error files. To submit the job one should execute:

$ dirac-wms-job-submit job.jdl
JobID = 11758

where the job.jdl file contains the job JDL description. The command returns the JobID which is a unique job identifier within the DIRAC Workload Management System. You can now follow the status of the job by giving:

$ dirac-wms-job-status 11758
JobID=11758 Status=Waiting; MinorStatus=Pilot Agent Submission;;

In the output of the command you get the job Status, Minor Status with more details, and the site to which the job is destinated.

Once the job in its final Status ( Done or Failed ), you can retrieve the job outputs by:

$  dirac-wms-job-get-output 11702
Job output sandbox retrieved in 11702/

This will retrieve all the files specified in the job Output Sandbox into the directory named after the job identifier.
