DIRAC quick start
Run first job in DIRAC
One needs to create as minimum 2 files. In this example test.jdl and script testJob.sh
Please put folling content to test.jdl (without line $ cat test.jdl)
$ cat test.jdl
Executable = "testJob.sh";
JobName = "%n_parametric";
Arguments = "%s";
Parameters = {"first","second","third","fourth","fifth"};
StdOutput = "StdOut_%s";
StdError = "StdErr_%s";
InputSandbox = {"testJob.sh"};
OutputSandbox = {"StdOut_%s","StdErr_%s"};
and folling content to testJob.sh (without line $ cat testJob.sh)
$ cat testJob.sh
#!/bin/bash
export
hostname
uptime
date
echo "Args: $*"
When these files are creted one can run job in grid
$ dirac-wms-job-submit test.jdl
JobID = [1467086, 1467087, 1467088, 1467089, 1467090]
One can see that 5 jobs were submited with ids 1467086, 1467087, 1467088, 1467089, 1467090. To check job status for first job (1467086) one can run following command
