Hi Hrabri, we discussed this issue at some length at GGF13 and were unsure as to how to proceed. We would like to be able to reference labeled attributes, but, I think we're still discussing how to implement this issue in the xsd schema depending on current tooling! I think, unfortunately, our choice of how we implement this in xsd will influence how we specify how to do this in the spec. Clearly this is not ideal and should be the other way round! Watch the JSDL space and let us know how you do this in the end. Cheers and take care, Ali On Tue, 5 Apr 2005, Rajic, Hrabri wrote:
Hi Ali,
Placeholders would be special variables like home directory or job id ($ sign prefixed below), which DRMAA could substitute in job attributes like the output path:
drmaa_set_attribute( $jt, DRMAA_OUTPUT_PATH, $DRMAA_HOME_DIR/MY_APP/my_job_output.$DRMAA_JOB_ID.out"

Hi Guys,
If you could give me a quick synopsis of what you consider placeholders and in what context, perhaps I can help from the JSDL perspective.
Cheers,
Ali

Andreas,
I would suggest we approach the question as two issues:
1) what are the global placeholders in DRMAA 2) in which (string typed) job attributes the placeholders could be used
Here are few questions that go with the above:
How is JDSL handling placeholders - nice to know? Do all major DRM systems support placeholders well? Do we need a new error code indicating failure in resolving a placeholder? Any other errors needed?

Hi Tim,
I fully agree there is a need for this. Please see
http://forge.gridforum.org/tracker/?aid=805
I raised it's priority to P2. I believe that issue must be solved with resubitted DRMAA spec.
Regards, Andreas

I'm sorry I wasn't clear. I guess the heart of my question is: How can create an arbitrarty template for the file and path name? Specifically what constant tells the DRM to insert job id into that filename template.
Said in Perl psuedo form:
drmaa_set_attribute( $jt, $DRMAA_OUTPUT_PATH + ":/tmp/my_job_output.$DRMAA_JOB_ID.out" );
# with that code job outputs look like /tmp/my_job_output.1.out /tmp/my_job_output.2.out /tmp/my_job_output.3.out
# without that code job outputs look like /home/harsch/script_name.o1 /home/harsch/script_name.o2 /home/harsch/script_name.o3
Is there a DRMAA_JOB_ID constant?

There is a simple solution, provided it works for you: to rely on the shell to supply the home directory path instead of DRMAA.

Hi all, I have a requirement for the app I'm writing ( using Schedule::DRMAAc ) which I'm trying to implement.
Normally the output files from jobs go to home directory and are of the form <jobname>.o<jobid>
I want to move the jobs to a subdir in /tmp, but retain the <jobid> in the filename. I tried this:
( $job_error, $diagnosis ) = drmaa_set_attribute( $jt, $DRMAA_OUTPUT_PATH, ":" . $tmpdir . '/' . __PACKAGE__ . '.' . $DRMAA_PLACEHOLDER_INCR . ".out" );
... but PLACEHOLDER is only for parametric jobs, I've been scanning the docs and have not found a placeholder for job id. Any ideas on how I could accomplish this task?
A similar task would be to move the job output path without changing the filename format at all. How could I do that?
